Hi Michael, with 7.5, there are several, alternative options to start the BaseX HTTP Server, which are listed at [1]. You either need to deploy the WAR file, or run basexhttp. a) if you deploy the WAR file, your databases will be contained in the archived webapp directory. With the latest snapshots, the database server will be automatically started along with the web server b) if you run basexhttp, you can specify DBPATH and the path to the webapp directory (WEBPATH) in the .basex configuration file. Hope this helps, feel free to ask for more, Christian [1] http://docs.basex.org/wiki/Startup#BaseX_HTTP_Server ___________________________ > I am running the 7.5 snapshot now, which has been a bit easier to work with, > but I still end up stuck in the same place. > > Ultimately, I would like to be able to: > run basex from a cli > offer REST > be able to interact with the db via python without using REST (so I can > perform maintenance with it off and maintain separation of duties) > and have all of these actions performed against the same database > > I know client spawns a different instance, so I have no plans to use it.

Unable to get jetty servlet to see existing database
by Michael Mendez 23 Oct '12

23 Oct '12

I have an existing install of basex running on a centos machine. The install runs fine, I am able to edit .basex files to point to the main database, and can run the client from anywhere and connect once I make .basex changes. I also have jetty6 running (on the same box) with the basex war package (7.3), which also runs, is accessible, and returns valid rest responses. My issue is the rest response shows no resources available, which as far as I can tell means it is not connecting to my existing database but creating (or created) it's own. Based on the documentation on the site, I have changed the web.xml's dbpath variable to the existing BaseXData path. I have used the same value I used in the .basex files, repackaged the .war, and restarted jetty, with no success. Other changes, like to the index.html in the war, will show, so I know I am rebuilding the war and viewing those changes correctly. What do I need to change to make the servlet of basex see a database folder already available? I have posted this question on stackoverflow as well: http://stackoverflow.com/questions/12976335/basex-servlet-doesnt-see-existi… Here is my web.xml: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>ATS</display-name> <description>REST Services for XML data</description>   <context-param> <param-name>org.basex.mode</param-name> <param-value>local</param-value> </context-param> <context-param> <param-name>org.basex.server</param-name> <param-value>local</param-value> </context-param>  <context-param> <param-name>org.basex.user</param-name> <param-value>admin</param-value> </context-param> <context-param> <param-name>org.basex.password</param-name> <param-value>admin</param-value> </context-param>   <servlet> <servlet-name>REST</servlet-name> <servlet-class>org.basex.http.rest.RESTServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>REST</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> </web-app> Thank you for your time!

running xquery scripts in REST server
by pw＠themail.co.uk 23 Oct '12

23 Oct '12

Hello List this is a noob question: I have BaseX 7.3 set up using httpserver. I can add a script to HTTPPATH and run it using http://{server:port}/rest?run=myScript.xq However, if I add myScript.xq to a database and try to run it then [http://{server:port}/rest/DB/myScript.xq ] then all I get returned is the XQuery script itself as a text file, the query doesn't run. >From the examples e.g. http://docs.basex.org/wiki/REST#GET_Requests_2 I thought that I am doing the same type of call, e,g, http://localhost:8984/rest/DB/mult.xq?a=21&b=2 What should I be doing?

Re: [basex-talk] Navigating a DOM
by Charles Foster 21 Oct '12

21 Oct '12

Hi Rainer, May I suggest XOM? [1]. Also, navigating a DOM tree is quite irksome in comparison to using XQuery/XPath. Perhaps you could consider slicing up your large document into "manageable chunks" (e.g. smaller documents) then inserting the smaller documents into BaseX with a view to then running XQuery to get specific parts of the logical large document when and as required. This approach would use less memory and may well be more efficient. May I also suggest checking out the BaseX XQJ API [2], where retrieved XML can be obtained as a Java DOM Node (e.g. Element / Document), StaX XMLStreamReader and SAX ContentHandler.

BaseX performance
by Christopher Harper 21 Oct '12

21 Oct '12

Hi @ll, I'm working on an CM/DM solution that uses BaseX as the metadata repository. This isn't my first stab at a DM/CM system just that the XML database portion is new to me Now when trying to scale the system up I find that I have created at least one offending query: count( distinct-values( let $item := doc('db')/repository/items/*//object for $path in $item/paths/path where starts-with($path/@name, '/Root/Temp/Import/') return $item/@uuid ) ) The '*/' could be replaced with 'documents/document' and 'folders', but that would be two separate queries and their individual times would still be offending. The goal of the query is to list items placed into a certain folder structure represented by items in the database. This seems like a straight forward query but I'm stumped at trying to get it to perform adequately. Any suggestions? / Chris

Using full Java regular expressions
by The Trainspotter 21 Oct '12

21 Oct '12

Hi, I'm currently converting my project to use BaseX instead of Saxon. One thing you can do in Saxon is provide a flag (an exclamation mark) to your regular expression to tell the matches function to use the Java regular expression processor, rather than the rather cut down expressions available in the XQuery spec. Is there anything similar in BaseX? If not what do you recommend to define a Java regular expression based function for XQuery? Thanks in advance, Gary

Dear Team, This is Riyaz from Hyderabad , India. I have been using X query since one and half year. I need help on the following query. When I add xmls of 199 MB to create collection using " new Add(xmlfilepath).execute(context)" (JAVA), it is taking 440 MB on hard disk and 3 mins to complete the process. Is there any other way to reduce the size and time? Thanks a ton in advance and would appreciate the earliest response.

Clusters
by Raymond Meester 16 Oct '12

16 Oct '12

Is it possible to set up a BaseX server as a clustered database (where data is synchronized over the servers by BaseX)? For example on two servers where a client session can be set up with "host1,host2". If one of the hosts fails then there is immediate fault tolerant failover to the second host (url). If this is possible is there an example available (couldn't find anything in this direction on GitHub)?

Add files to the database
by Raymond Meester 16 Oct '12

16 Oct '12

Charles, thanks for the examples. I first thought using the core API, like "new Add(doc).execute(context); ", but to get working you need conversions and ToString methods and loose the direct manipulation options. I needed a concurrent set up anyway. What I also didn't get from the core library; when using multiple instances I got a FileLockException in the stack trace (as expected), but then the general message "org.basex.core.BaseXException: Improper use? Potential bug?" was shown. Maybe an error message about the filelock and concurrency would be clearer as its not a bug. There are some databases like SQLite that support concurrency (to some extend) while directly using a OS file system, but that lead often to unexpected results (locking on network shares for example).

update database with insert and db:open-id
by Tim Belschner 10 Oct '12

10 Oct '12

[BaseX 7.3 with the internal editor] Hello, as a part of a query, I need to update more than ten thousand database entries with an additional attribute. For this, I thought about getting the node IDs with db:node-id(), storing them in an element sequence as attributes and use them afterwards as an identifier for the "update insert". Unfortunately, it takes around 22 seconds to update all database entries. After some testing I got two bottlenecks: 1. the "insert node ." command and 2. the "db:open-id()" command Both of them cause a processing time of around 10 seconds each. Is there a way to increase the update performance significantly? Maybe by setting some options of BaseX or using a different approach? Best regards Tim Here is an example code (no practical sense just to demonstrate the current code for the updates): ----------------------------------CODE-------------------------------------- ------- (: create a list with the node IDs:) declare function local:GetDBIDs ($seq as element()+) as element()+ { for $element in $seq let $DBID := db:node-id($element) return ( element {'Doublet'} { attribute{'DBNodeID'}{$DBID} } ) }; (: ##### MAIN PART ##### :) declare variable $dbname := 'db_enum_test'; let $elements := DBSection let $doubletIDs := element{'Doublets'}{local:GetDBIDs($elements/DatabaseEntry)} for $element at $pos in $doubletIDs/child::* return ( insert node (attribute {'DB_ID'}{xs:string(xs:integer('100000') + $pos)} ) into db:open-id( $dbname, xs:integer(data($element/@DBNodeID)) ) ) ----------------------------------CODE-------------------------------------- ------- and a query to create an example database: ----------------------------------DB---------------------------------------- ----- let $entries := for $i in (1 to 10000) return ( element {'DatabaseEntry'}{attribute {'id'}{xs:string($i)}, attribute {'word'}{concat('Scheduler_',xs:string($i*$i))}, attribute{'type'}{'INT32'}} ) let $entries2 := element {'DBSection'}{$entries} return ( db:add("db_enum_test", document { $entries2 }, "DB") ) ----------------------------------DB---------------------------------------- -----

db creation mini tool
by Hans-Juergen Rennau 08 Oct '12

08 Oct '12

Hello, a little question. I would like to write a mini "tool" which loads an XML file into a database, creating the db if it does not yet exist and overwriting the current content if it does already exist. This script achieves the goal: <commands> <drop-db name="mydb"/> <create-db name="mydb">myxmlfile.xml</create-db> <list/> </commands> But as the script interface does not (yet?) support input parameters, I have to edit the script for each use. Using an XQuery script, on the other hand, is not possible as there is no function for creating a database, if I have not overlooked it in the documentation. My question: is there an alternative which allows to specifiy db name and file name as command line parameters, or is that presently not possible? Many thanks for any information, Hans-Juergen Rennau PS: I would not mind the editing myself, but a tool with call parameters is helpful when spreading the word "BaseX" among the colleagues: providing some useful tools to them using BaseX, one has to instruct them first how to load their data into BaseX, and of course it would be nice to give them a simple call, rather than an instruction how to edit a sample and then call it.

XQJ: Exception using Saxon9 TransformerFactoryImpl
by David Oguns 06 Oct '12

06 Oct '12

I am trying to perform a basic document insert using the XQJ API communicating with a standalone BaseXServer. I have a lot of dependencies on my classpath (I'm sure this affects JAXP's behavior), including Saxon, Xerces, Xalan, and probably a few versions of some of them. When I set the transformer factor explicitly to Xalan, there is no exception, but otherwise it appears Saxon is being used and it down throw an exception. I have a very high opinion of Saxon so I have my doubts that it's doing anything illegal with respect to the standards, so I thought I should ask what is going on. This is the property I can set to get rid of the problem: System.setProperty("javax.xml.transform.TransformerFactory", "org.apache.xalan.processor.TransformerFactoryImpl"); Here is the exception and stack trace: javax.xml.xquery.XQException: XQJTO013 - Values of 'standalone' and 'omit-xml-declaration' conflict Root Cause: net.sf.saxon.trans.XPathException: Values of 'standalone' and 'omit-xml-declaration' conflict at MyClass.main(MyClass.java:82) at net.sf.saxon.serialize.XMLEmitter.writeDeclaration(XMLEmitter.java:226) at net.sf.saxon.serialize.XMLEmitter.openDocument(XMLEmitter.java:143) at net.sf.saxon.serialize.XMLEmitter.startElement(XMLEmitter.java:303) at net.sf.saxon.event.NamespaceReducer.startElement( NamespaceReducer.java:72) at net.sf.saxon.event.ReceivingContentHandler.startElement( ReceivingContentHandler.java:290) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source) at org.apache.xerces.impl.XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at net.sf.saxon.event.Sender.sendSAXSource(Sender.java:400) at net.sf.saxon.event.Sender.send(Sender.java:154) at net.sf.saxon.IdentityTransformer.transform(IdentityTransformer.java:35) at MyClass.main(MyClass.java:82) And here is the relevant code: XQDataSource xqs = new BaseXXQDataSource(); xqs.setProperty("serverName", "localhost"); xqs.setProperty("port", "1984"); XQConnection conn = xqs.getConnection("admin", "admin"); try { XQStaticContext context = conn.getStaticContext(); XMLStreamReader xmlReader = XMLInputFactory.newInstance().createXMLStreamReader(newFileReader(args[0])); XQPreparedExpression xqpe = conn.prepareExpression("declare namespace output = \"http://www.w3.org/2010/xslt-xquery-serialization\";declare option output:omit-xml-declaration \"no\";declare variable $doc external;\nfn:put($doc,\"jc003.xml\")", context); //xquery doc('oguns/jc001.xml') try{ xqpe.bindDocument(new QName("doc"), xmlReader, conn.createDocumentType()); XQResultSequence xqrs = xqpe.executeQuery(); } finally { xqpe.close(); } } finally { conn.close(); }

Jetty, locking files with webDAV and the possibility to use other web servers
by France Baril 05 Oct '12

05 Oct '12

Hi, Our context: - Multiple authors create/modify content stored on BaseX concurrently (content is split into multiple small topic files) - Authors access content using Data Source in Oxygen Issue - No locking mechanism to prevent multiple authors to make changes to the same file at once (leads to overwriting of the other author's changes). Research done seems to indicate that Jetty doesn't support webdav locking. - We couldn't get it working. - Talks with Oxygen validated this conclusion: http://www.oxygenxml.com/forum/post22862.html#p22862 Since the documentation says that Jetty is the default server (as opposed to it being the only server?), we are thinking we could maybe use another one. - Did anyone ever attempt that? - What would the steps to doing so be (Documentation only says how to work with Jetty)? - Anything possible/known issues? Compatibility or otherwise? -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

index:facets()
by Cerstin Elisabeth Mahlow 05 Oct '12

05 Oct '12

Hi, after Andreas recommended using index:facets(), my application speeds up. However, I don't think that this is the best solution. The database, I apply this function to is changing constantly. As the function is using the index, I would have to re-create the index first, is this correct? So that the functions would give wrong results most of the time. And I found another strange thing: I had to delete some nodes and re-created all indexes. However, index:facets() still gives the information from the status *before* the deletion, i.e., it counts nodes that aren't there anymore. Therefore I don't use it. count(//entry/selected[text () = "yes"]) gives the correct result, index:facets("collect", "flat")//element[@name = "selected"]/entry[text() = "yes"]/@count/data() still gives the wrong result, i.e., the result that was correct some days ago. Is this a bug or a feature? Best regards Cerstin -- Dr. phil.

XSLT import with relative path fails
by Charles Kowalski 04 Oct '12

04 Oct '12

Hi, I am trying to use TEI-to-xhtml stylesheet* provided by the tei consortium using the saxon HE transformer. The importing of xsl dependencies fails with this error: XTSE0165: I/O error reported by XML parser processing file:/../xhtml2/tei.xsl: /../xhtml2/tei.xsl (No such file or directory) The specific file i try to run is The actual href in the xsl:import is <xsl:import href="../../../xhtml2/tei.xsl"/> From the error message it looks as if the relative path: "../../../xhtml2/tei.xsl" is converted to the (non-existent) absolute path: "/../xhtml2/tei.xsl The same transformation works fine if called from the cli with java -jar path/to/saxon9he.jar some-tei.xml path/to/tei-stylesheets/xml/tei/stylesheet/profiles/tei/html/to.xsl Is there some sort of url resolution happening on behalf of basex before the xsl is passed to saxon? I will try to reproduce with a set of less complex xsl files but it seems like the issue lies with relative path resolution. Thanks, Alexandros *You can download the latest stylesheets from sourceforge at: http://sourceforge.net/projects/tei/files/Stylesheets/tei-xsl-6.14.zip/down…

deleting and updating nodes
by Cerstin Elisabeth Mahlow 03 Oct '12

03 Oct '12

Hi, I encountered strange behavior in the GUI (version from September 30 of 7.5 beta): In my database of collected node-ids ('collect'), I had to remove some thousands, because the documents the nodes where referring to in the main database ('DB') had to be removed as well. So I had a database ('remove') with the documents like this: <list> <item>abc.xml</item> <item>def.xml</item> </list> And then I used this for the 'collect' database: for $i in //entry let $n := $i/node let $d := replace(db:open-id('DB', $n)/base-uri(), 'DB/', '') where db:open('remove')//item[text() = $d] return delete node $i I tested it (it removed the correct nodes) and then applied it to the whole thing and everything worked fine. In a second step, I deleted the respective texts from the original DB (to be precise, I created a new one without some texts and with whitespace chopping OFF, because the whitespace problem was another issue). And then I have to change the node-ids in my 'collect' database, so I tried this: for $node in //entry/node let $id := data($node) let $path := replace(db:open-id('DB', $id)/path(), 'Q\{.*?\}', '*:') let $base := replace(base-uri(db:open-id('DB', $id)), 'DB', 'newDB') let $newid := xquery:eval(concat('db:node-id(doc("', $base, '")', $path, ')')) return replace value of node $node with $newid It worked OKish on my test data: I removed irrelevant nodes first, made a copy and than applied the node-changing. But I got an error message, that some resources would not exist -- the ones I wanted to remove and thus the ones for which no node should be in 'collect' anymore. I created new test data, removed the nodes and immediately applied the changing, and then it worked. For the whole data, I successfully removed the nodes, I thought. And then regardless of using this database or making a copy and using this, I get an error message that a resource would not exist. How can I find out (in the GUI) where exactly the error occurs, i.e., for which $node? In the query info I only see "Stopped at line 1, column 14 in ...xq" Somehow, nodes that should have been deleted seem to still be there. The names of the files I created 'DB' from in the first place included special characters and spaces. The file I list the documents to be removed is a UTF-8 file where the file names appear also with special characters and spaces. Maybe the error is in there: One file name is "Brontë,-Charlotte.xml". Apparently, matching doesn't work. When I list the base-uri the node-ids belong to, I get Brontë,-Charlotte.xml, but the node will not be deleted, so it doesn't match the respective entry in the corresponding list. So how do I deal with this? Best regards Cerstin -- Dr. phil.
