Cannot execute xxforms:get-request-parameter in XPL - XSLT processor
by software developer 31 Dec '10

31 Dec '10

Hi, I get the error: XPath syntax error at ... in {...get-request-parameter('quer...}: Cannot find a matching 1-argument function named { http://orbeon.org/oxf/xml/xforms}get-request-parameter(). *Note: external function calls have been disabled* when I attempt to execute a pipeline with: <p:processor name="oxf:xslt"> <p:input name="config"> <xsl:stylesheet version="2.0"> <xsl:template match="/"> <TargetURL> <xsl:variable name="location" select="/Configuration/XMLDB/Location/text()"/> <xsl:variable name="name" select="/Configuration/XMLDB/Name/text()"/> <xsl:variable name="query" select="xxforms:get-request-parameter('query')"/> <xsl:value-of select="fn:concat($location,'/',$name,'?',$query)"/> </TargetURL> </xsl:template> </xsl:stylesheet> </p:input> <p:input name="data" href="#configuration"/> <p:output name="data" id="Target"/> </p:processor> Is XPL not the correct location to retrieve the HTTP request params (should I be doing it in page-flow.xml instead?)

Multiple producers/writers for one collection and concurrency
by Jan Vlčinský (CAD) 31 Dec '10

31 Dec '10

Hi This topic was mentioned few times before, but it is key aspect of my application, so I will try anyway. *Question*: What is recommended approach for application, where exists multiple document producers which shall store/modify documents in one, share collection. *Background* - Having *feeds*, which might deliver some new messages. - *Multiple preprocessing processes* - preprocessing the messages before storing them in collection (Python, celery and RabbitMQ to be ready for processing bigger amount of incoming messages in parallel) - Having *single process for write access to my BaseX collection*(arranging this is not very easy for me so far) - There are some read only queries for stored messages, there are no problems with this as it shall be easy to run multiple read-only queries concurrently. *Assumptions* If I am wrong here, please, correct me. - one collection can be written/modified only by one process at given moment, other attempts to write are rejected and these attempts will fail. In other words - one collection can be opened only by one process (or are multiple opening clients allowed as long as the do not modify database concurrently?) - read only queries are easy as they can be run concurrently without blocking/rejecting *Current approach* 1. Multiple preprocessing processes are concurrently sending documents into single basex-storage queue in RabbitMQ 2. There is single one-process worker, consuming documents from queue basex-storage which does all the work with adding documents for given collection. *Wishes* Managing single write process adds quite complexity to whole solution. It would be nice, if I can write to single collection by multiple processes at once and could expect success. Any comments are welcome Best regards Jan

Big recursive XQueries
by Charles F. Munat 31 Dec '10

31 Dec '10

I have a BaseX backed website which stores all the pieces of the page in the DB. There is a significant amount of processing to be done. Pretty much any piece of the page can have effective or expiration dates (so that page parts can come and go on schedule). Some pages have dynamic elements, such as a Twitter feed. The page is build from objects which are wrapped in frames (for adding temporal and styling parameters), which are inserted into columns, which go into rows, which make up a page (which itself is wrapped in a template). So there is a lot of recursion. I do the recursion using local functions. It works well, but the page-building query is getting enormous, most of which is all these functions to insert parts of the page, often recursively. I am wondering what the best practice would be for this. I'm working in Scala, and I could break the process up into repeated passes hitting the db with a different query for each, but it seems to me one big query will almost certainly be faster. But including all the local functions in the query makes it huge. Is there some way to compile and load the functions once on startup, and then just run a small XQuery that calls functions which call functions, etc.? Any ideas (or resources) for ways to optimize the query? Everything gets reused, so there is very little nesting -- mostly references are passed. For example: <pages> <page> <id>1</id> <rows> <row id="2"/> <row id="3"/> </rows> </page> </pages> <rows> <row> <id>2</id> <columns> <column width="18"> <frames> <frame id="4"/> <frame id="5"/> </frames> </column> <column width="6"> <frames> <frame id="6/> </frames> </column> </columns> </row> </rows> <frames> <frame> <id>4</id> <contents> <content id="7"/> </contents> </frame> </frames> <contents> <content type="TEXT"/> <id>7</id> <body> <p>Some text here.</p> </body> </content> <content type="WIDGET"/> <id>7</id>  </content> </contents> Thanks!

How to retrieve HTTP request parameters and use them in XQuery with BaseX
by software developer 30 Dec '10

30 Dec '10

Hi, eXist DB offers this facility via HTTP related functions: http://en.wikibooks.org/wiki/XQuery/Checking_for_Required_Parameters What I want to achieve is pass parameters to XQuery dynamically (not necessarily by using HTTP request parameters, although that appears to be one way of achieving this). Is that possible in BaseX; if yes, how? Thanks.

Database creation from a directory tree
by David leigh 28 Dec '10

28 Dec '10

I've just installed 6.3.4 and I've noticed a difference from version 6.1. In the GUI in 6.1, I can create a database from a whole directory hierarchy of 5,681 individual XML files. When I point to the same source file directory and using the 6.3.4 GUI (which I installed with a pre-release version of the installer), it only processes 14 files. No error message (that I saw) was produced. The behavior that I'm wanting is what 6.1 does. Glad to help in solving the problem. Additional question: That was in the GUI. I'd like to do the same thing using the command line with the .JAR file, but somewhere my syntax is not right. Additionally, all the XML files have NO EXTENSION so I don't know how to specify that either in the command line. So, any help in that area would also be appreciated. Thank you, David <mailto:david@leighweb.com> DavidEmailSig

Complete control from the command line
by David leigh 25 Dec '10

25 Dec '10

Hi, I'm new to basex and NOT a java person at all. I'm creating an application where a basex database is used to search for song lyrics. I'm using the autoit3 scripting language in Windows and interfacing to basex using the basex61.jar on the command line with the output file. I'm starting the server and then using the client for the queries. So far so good. The performance is amazing in both loading the database from thousands of individual XML documents and in querying the database. Quite pleased. My desire is to have an app where ALL the components reside in one directory or its subdirectories. I also want to be able to create and recreate the basex database programmatically using the CREATE on the command line. I understand that there exists a basex config file where certain parameters, like the data store location, can be set, but that the location of this file is assumed/fixed.i.e. I can't just put it anywhere I want it (like in the single directory I want this all to reside in). It seems that there are perhaps actual java commands that I could use when I launch the server and/or client that would allow me either to specify the location of the basex config file OR simply pass the parameters that I want to pass for specifying the location of the database. Unfortunately, none of the documentation on the site seems to address this level of interaction. Is there another source of more detailed documentation somewhere or could someone please guide me in this? I think it all boils down to how to tell basex, via the command line, where to put the data (for the server) and where it resides (for the client). Thank you very much! <mailto:david@leighweb.com> DavidEmailSig

Problems with XQuery matching records by compound key

There I was unable to open the collection with complains about Index out of bound Java error 5. Then I dropped the database and created it again. Trying to run the XQuery I got the same error. 6. returned back to 6.3.4 7. rewrote it to shorted sample, shown above I wonder, what I am doing wrong. Any advice? With best regards Jan Vlčinský

Use with Google App Engine
by Min Idzelis 20 Dec '10

20 Dec '10

I realize that BaseX can't be used as-is on the Google App Engine. The question I have is how much work would it be to get it up and running on the App Engine's datastore API instead of whatever you are using for indexing/storage. There is no access to a filesystem. The datastore does have a concept of hierarchical (parent-child) entities. In the datastore, the only operations that are supported are: get/put by key, inequality (<, >, =) filters, and a way to limit results that have a common ancestor (key). Would this be enough to support BaseX? Thanks, Min

Responses in XML, uisng REST
by Mahender Didwania 17 Dec '10

17 Dec '10

Hi, BaseX returns XML for URLs like http://localhost:8984/basex/jax-rx/; however, database creation commands or collection creation commands result in text/plain content-type and plain-text being returned in response. Perhaps it will be useful, in pure XML processing apps, for these responses to also be in XML. Something like, <jax-rx:results xmlns:jax-rx="http://jax-rx.sourceforge.net"> <jax-rx:response status="201">Database 'Test' created in 38.22 ms.</jax-rx:response> </jax-rx:results> Regards, Mahender.

Hierarchical collections via REST

Hi, The changelog for 6.3.1 says: [ADD] REST: support for hierarchical collections added; details will follow I am using 6.3.4, but if I send a post request to /server/collection/subcollection, only the collection gets created (and the document is added to collection, not to subcollection). In view of the above, could you please throw more light on how the subcollections can be created using REST and how documents can be added to subcollections using REST? Thanks, Mahender

Limit of 32 attributes per element
by Peter Fischer 15 Dec '10

15 Dec '10

Dear all, when testing BaseX with the TPoX benchmark workload (http://tpox.sourceforge.net/) I could not load the input data set since it contains elements with more than 32 attributes. The large number of attributes stems from the FIXML data (http://www.fixprotocol.org/specifications/fix4.4fixml) contained in the workload, so it is not just a stress test by the benchmark designers. Is there any way to lift this limitation?

BaseX Server installation.
by Huib Verweij 14 Dec '10

14 Dec '10

Hi, I would like to install BaseX on a server. So far I've installed it on my dev machine and on a test server under my account, but now we are moving to a server where BaseX will just be started by a script or something and run in a folder which is not anyones home folder. The problem I think there will be is that BaseX takes it's configuration information always from ~/.basex, which will not work in our server setup I assume. Am I correct in assuming this will cause headaches for our sysadmin or am I missing something? Will 6.5 change this situation where the config file is always read from Util.homeDir()? Ideally we would just like to pass the location of the config file to the server when it starts, I suppose. In the config file we can then specify the location of the data folder etc. Kind regards, Huib.

Hi, Many thanks and I very much appreciate the lightening fast response. Upon reviewing the steps mentioned by you and what my maven build does, I found the only material difference (from the pt. of view of ability to invoke server from command-line) was that the class name was changed (for invoking the REST server) from org.basex.examples.jaxrx.StartJaxRx to rg.basex.api.jaxrx.JaxRxServer.

Can't use REST with 6.3.3
by Mahender Didwania 13 Dec '10

13 Dec '10

Hi, Two things: 1. Earlier I was using version 6.2.9 and the class StartJaxRx.java seemed to work fine. The need is to have the ability to invoke the server from a script. I can't find the StartJaxRx in 6.3.3 any more. Using the old class with 6.3.3, the server says it started up fine, but when I attempt to access it over HTTP/REST, I get error for /basex/jax-rx (note that /basex/ is okay): Problem accessing /basex/jax-rx/. Reason: tried to access method org.basex.server.ClientSession.execute(Ljava/lang/String;Ljava/io/OutputStream;)V from class org.basex.api.jaxrx.BXOutput Caused by: java.lang.IllegalAccessError: tried to access method org.basex.server.ClientSession.execute(Ljava/lang/String;Ljava/io/OutputStream;)V from class org.basex.api.jaxrx.BXOutput at org.basex.api.jaxrx.BXOutput.exec(BXOutput.java:62) at org.basex.api.jaxrx.BXJaxRx$1.code(BXJaxRx.java:61) at org.basex.api.jaxrx.BXCode.run(BXCode.java:56) at org.basex.api.jaxrx.BXOutput.write(BXOutput.java:51) at com.sun.jersey.core.impl.provider.entity.StreamingOutputProvider.writeTo(StreamingOutputProvider.java:71) at com.sun.jersey.core.impl.provider.entity.StreamingOutputProvider.writeTo(StreamingOutputProvider.java:57) at com.sun.jersey.spi.container.ContainerResponse.write(ContainerResponse.java:299) at com.sun.jersey.server.impl.application.WebApplicationImpl._handleRequest(WebApplicationImpl.java:1326) at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:1239) at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:1229) at com.sun.jersey.spi.container.servlet.WebComponent.service(WebComponent.java:420) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:497) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:684) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:511) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:401) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:766) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:928) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:549) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.jetty.bio.SocketConnector$Connection.run(SocketConnector.java:228) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) 2. For version 6.1, you provide various files, including a .zip, on your website; for 6.3.3, you only provide basex.jar and basex-api.jar. I had earlier created my own maven build to include all dependencies (including the ones from java.net repository), but as noted above, I cannot get 6.3.3 to work. Could you please provide a .zip file for every release like you have for 6.1 on your web-site (merely replacing BaseX61.jar with basex.jar and BaseX61-jaxrx.jar with basex-api.jar (for 6.3.3 versions) does not seem to help)? Thanks, Mahender.

Ihre Software auf der Heft-DVD in c't Mac & i
by Stephan Ehrmann, c't 10 Dec '10

10 Dec '10

(Please scroll down to find the english version of this mail.) Sehr geehrter Software-Hersteller, am 26. Februar erscheint erstmals c't Mac & i, das neue Sonderheft rund um Apple. Die Redaktion legt eine Heft-DVD mit attraktiven Voll- und Spezialversionen für Mac OS X bei. Mit diesem Schreiben möchten wir Sie bitten, unseren Lesern für diese Aktion attraktive Programme zur Verfügung zu stellen, die sie anderweitig nicht bekommen und die es insbesondere nicht zum Gratis-Download im Internet gibt. Sie als Hersteller profitieren von dieser Aktion ebenfalls: Sie stellen Ihre Software einem großen Kreis interessierter Mac-Nutzer vor, können bei dieser Gelegenheit auf andere Produkte hinweisen und gegebenenfalls auch Upgrades von einer älteren auf eine aktuelle Vollversion anbieten. Hersteller, die uns in der Vergangenheit Vollversionen für c't-Heft-DVDs zur Verfügung gestellt haben, waren positiv überrascht vom Erfolg solcher Aktionen. Es kommen durchaus auch etwas ältere Vollversionen in Frage, sofern sie mit aktueller Mac-Soft- und Hardware noch funktionieren. Wenn Sie die Idee grundsätzlich für gut halten, die Verbreitung einer Vollversion aber für Sie nicht in Frage kommt, können Sie uns auch eine Spezialversion anbieten, also eine im Funktionsumfang gegenüber der Vollversion eingeschränkte Variante Ihres Programms. Bitte stellen Sie aber sicher, dass unsere Leser eine sinnvolle Auswahl an Funktionen geboten bekommen: ein CAD-Programm, das nicht speichern kann, ist aus unserer Sicht ebenso wenig brauchbar wie ein Videoschnittprogramm, das keine Filme exportiert. Bitte beachten Sie, dass wir an zeitlich limitierten Demo- oder Testversionen ebensowenig interessiert sind wie an Shareware und Open-Source-Software, weil unsere Leser solche ohnehin gratis aus dem Internet gratis herunterladen können, nicht selten in aktuelleren Versionen. Ob Sie die Programme installations- und betriebsbereit zur Verfügung stellen oder eine Registrierung auf Ihrer Website voraussetzen, auf die wir dann von unserer DVD-Bedienoberfläche aus verlinken würden, ist Ihnen überlassen. Wenn Sie eine Website zum Registrieren aufsetzen, möchten wir Sie bitten, zu versichern, dass Sie die Adressen unserer Leser nicht missbrauchen und nicht etwa an andere Unternehmen weitergeben. Außerdem müssten Sie bitte sicherstellen, dass die Registrierung mindestens sechs Monate nach Erscheinen der c't Mac & i, also bis 31. August 2011, möglich ist. Viele Leser installieren interessante Software nicht unmittelbar nach Erscheinen einer Ausgabe, sondern dann, wenn sie sie brauchen. Der Ärger ist groß, wenn sie dann nicht mehr funktioniert. Welche Software Sie uns zur Verfügung stellen wollen, was diese Software auszeichnet, wo wir sie finden, ob wir in unserer systemübergreifenden DVD-Oberfläche auf eine Registrierungswebseite verlinken sollen und wie deren URL lautet, ob es sich um eine Voll- oder eine Spezialversion handelt, was sie regulär kostet und so weiter können Sie direkt in unserer Datenbank eintragen. Über diesen Link können Sie neue Programme anlegen: <http://www.heise.de/bin/ct/cdprod.pl?id=neu&prod=sp1103> Wenn Sie uns mehrere Programme zur Verfügung stellen wollen, klicken Sie bitte nicht den Back-Button im Browser, sondern rufen die URL erneut auf, um einen neuen Datensatz zu generieren. Falls Sie allen Lesern dieselbe Seriennummer zur Verfügung stellen wollen, um die Installation zu erleichtern, tippen Sie die Seriennummer bitte genau so, wie sie später in Ihrer Software eingefügt werden soll, in das Feld "Seriennummer für die Vollversion". Bitte probieren Sie unbedingt sorgfältig aus, ob diese Seriennummer 1:1 in der Programmversion, die Sie uns zur Verfügung stellen, funktioniert. Auf der danach folgenden Seite können Sie schließlich noch jeweils einen Screenshot pro Software hochladen, der am Ende auf der HTML-Bedienoberfläche der DVD zu sehen sein wird. Nachdem Sie alle Daten eingegeben und durch Klicken des OK-Buttons gespeichert haben, erhalten Sie eine automatisch generierte E-Mail, die den Eingang Ihrer Daten bei uns bestätigt und einen Link enthält, über den Sie Ihre Daten nachträglich editieren können. Wir weisen explizit darauf hin, dass die Redaktion von allen Programmen, welche auf diesem Weg für c't Mac & i angeboten werden, die aus ihrer Sicht attraktivsten aussucht und dass Vollversionen attraktiver sind als Spezialversionen. Selbstverständlich informieren wir Sie, ob Ihre Software auf der Heft-DVD vertreten sein wird. Bitte antworten Sie auf diese Mail, falls Sie Fragen haben, sich im Unklaren sind, ob sich eines Ihrer Programme dafür eignet oder natürlich auch gern, wenn Sie Schwierigkeiten mit dem Prozedere haben sollten. Und noch eine Bitte: Wir sind Ihnen verbunden, wenn Sie die Angelegenheit vertraulich behandeln. Mit freundlichen Grüßen Stephan Ehrmann Chefredakteur Mac & i, www.mac-and-i.de, und heise Software-Verzeichnis, www.heise.de/software, Stellv. Chefredakteur c't, www.ct.de ################################################################################ Dear software producer, on February 26th we will publish the first issue of c't Mac & i, our new special about the Apple universe. Part of the magazine will be a covermount DVD loaded with attractive software (full and special editions) for Mac OS X. We would like to ask you to provide our readers with great software that is otherwise not available, especially not as a free download on the Internet. You as a software producer benefit also from this promotion: You are introducing your software to a broad audience of interested Mac users, you can use the opportunity to point out your other products and you could, where applicable, offer updates to the latest version of the software. Software makers who have provided us with software in the past were positively surprised by the success of these promotions. Older software versions can also be considered if they are compatible with the latest Mac system software and hardware. If you basically like the idea but the spread of a full version is out of the question you can also offer us a special edition of your software, i. e. with limited functionality. Please make sure that the software still offers a meaningful selection of functions: a CAD software unable to save a file is as useless as a video-editing program without the ability to export movies. Please note that we are neither interested in time-limited demo or test versions nor shareware or open-source software. These can be already downloaded from the Internet for free. It's up to you whether you provide your software ready-to-use or if you require an online registration. We would link to your registration page from our DVD user interface. We would like to ask you not to abuse the registration data of our readers and not to sell it or pass it to other companies. Please keep in mind that a registration page has to be available at least six month after the publication of the magazine, in this case August 31st, 2011. Readers might only install the software when they need it, not when the magazine is bought. You can enter the specifics of your software, where we can download a distribution archive, if we should link to a registration page, what kind of version it is, how much you normally charge, etc directly in our database. Please follow the link <http://www.heise.de/bin/ct/cdprod.pl?id=neu&prod=sp1103> to enter new programs. If you want to provide more than one program please do not use the back button of your web browser but follow the link again to create a new record in the database. Should every reader use the same serial number during the software installation please enter it in the field "Serial Number for full Version". Please test thoroughly if software and serial number match. On the following pages you can upload a screenshot that will appear on the HTML navigation pages of the DVD. After having entered all the data and saved it by clicking OK you will receive a system-generated email confirming the reception of your data and providing a link for later data changes. Please be advised that the editorial staff makes the final decision which programs will be included on the DVD. Full versions are more attractive than special versions. You will, of course, be informed if your software will be included. Please respond to this email if you have any questions or are uncertain whether one of your software products is suitable or whether you have problems with our procedures. One final request: We would be very grateful if you would keep this matter confidential, thank you.

OK, now it prints something like this: declare function local:get ( $arg as xs:string ) as xs:string { let $result := collection()/BOT-L/memory/variable[@name=$arg]/@value return ( if ($result then $result/string() else fn:concat('"',fn:concat($arg,' not found"')) ) ^ ^ ^ [XPST0003] Expecting ")", found "t". }; declare updating function local:set ( $name as xs:string, $value as xs:string ) { if (collection()/BOT-L/memory/variable[@name=$name]) then replace value of node collection()/BOT-L/memory/variable[@name=$name]/@value with $value else insert node element variable { attribute name {$name} , attribute value {$value} } into collection()/BOT-L/memory }; let $botName := xs:string(local:get("_botName_")) let $lastEventTime := xs:dateTime((collection()/BOT-L/event[@from=$botName]/@dateTime)[1]) let $now := fn:current-dateTime() let $duration := $now - $lastEventTime return ($duration > xs:dayTimeDuration('PT60S')) org.basex.core.BaseXException: Stopped at line 4, column 34: [XPST0003] Expecting ")", found "t". at org.basex.core.Command.execute(Command.java:66) at org.basex.core.Command.execute(Command.java:78) at com.avatar_reality.ai.XQuery.execute(XQuery.java:21) at com.avatar_reality.ai.BotCommandProcessor.executeCommands(BotCommandProcessor.java:432) at com.avatar_reality.ai.BotCommandProcessor.processEventTriggers(BotCommandProcessor.java:370) at com.avatar_reality.ai.BotCommandProcessor.processEvent(BotCommandProcessor.java:339) at com.avatar_reality.ai.BotCommandProcessor.processEvent(BotCommandProcessor.java:310) at com.avatar_reality.ai.BotCommandProcessor.receiveTimerEvent(BotCommandProcessor.java:553) at com.avatar_reality.blue_mars.iam.framework.behavior.BotLBehavior.update(BotLBehavior.java:67) at com.avatar_reality.blue_mars.iam.framework.IamBot.update(IamBot.java:391) at com.avatar_reality.blue_mars.iam.framework.BotProxy.update(BotProxy.java:129) at com.avatar_reality.blue_mars.tkclient.TKClientAdapter$BotUpdater.run(TKClientAdapter.java:1283) at java.lang.Thread.run(Thread.java:680) MUCH better. :) Mark

What abot publishing Python API to PyPi
by Jan Vlčinský (CAD) 09 Dec '10

09 Dec '10

Hi I am using Python API heavily and now run into situation, when I need the library easily usable from more projects. Natural choice would be to make it a module or a package and publish it to PyPi, because then it can be installed quickly. I am willing to spend some hours on this to make it more available. But I will need some assistance from original authors as it is good practice to fill in licence, author, url etc. With whom can I discuss that? Jan PS: I am neither Python nor PyPi guru, I just feel, I can manage to do this task within few weeks. -- *Ing.
