Re: [basex-talk] Can't build using maven 3
by Michael Seiferle 10 Nov '10

Hi Stefano, (this time with cc to the list, as this might be of general interest :-)) sorry again for the inconvenience. We currently have no automatic deployment of the minor Version jars to our repository (we are about to change that soon, hopefully). The recoomended and "clean" solution is installing the latest repository version of BaseX into your local subversion repository via: > $ cd basex > $ svn up > $ mvn -DskipTests=true install This should avoid the errors below. Let me know if this helps and feel free to ask more! Kind regards Michael Am 10.11.2010 um 19:41 schrieb Stefano Santoro: > [WARNING] The POM for org.basex:basex:jar:6.3.2 is missing, no dependency information available > Downloading: http://repository.codehaus.org/org/basex/basex/6.3.2/basex-6.3.2.jar > Downloading: http://www.inf.uni-konstanz.de/dbis/basex/maven/org/basex/basex/6.3.2/basex… > Downloading: http://repo1.maven.org/maven2/org/basex/basex/6.3.2/basex-6.3.2.jar >

predicate evaluation issue
by Martin Gieseking 10 Nov '10

10 Nov '10

Hello again, :) I think, I've found another bug. This time it's somehow related to implicit type casting. When running the query /a/b[@*=2] on the following XML document, both b nodes are selected, although the first one has no matching attribute. /a/b[@*='2'] returns the correct node. <a> </a> Best regards, Martin

types & encoding when talking to BaseX server
by Godmar Back 10 Nov '10

10 Nov '10

Hi, I have 2 questions regarding: https://svn.uni-konstanz.de/dbis/basex/trunk/api/etc/java/BaseXClient.java a) create() takes an InputStream. Which character encoding is assumed (I'm guessing UTF-8?) b) Query.next() returns a String. Is there a way/need to determine the type of the Query result (e.g., String, boolean, etc.)? (Or is an XQuery's result type statically determinable, in which case this would not be needed?) - Godmar

Re: [basex-talk] BaseXGUI
by Christian Grün 10 Nov '10

10 Nov '10

Dear Luca, > Hi, I'm playing with basex and succesfully running a server and the basic client BaseXClient remotely via an internet connection. I'm trying to do the same thing with BaseXGUI but I can only administer the remote server via BaseXGUI. Is there a way to connect and issue commands to a remote server using BaseXGUI? Currently, that's not possible; the visualization demand a much tighter integration with the backend, which cannot be realized via the client/server architecture. As this a frequently requested feature, we might add a console mode in a future version to allow text-based requests via the GUI. Best, Christian PS: mails to the mailing list are preferred.

erroneous evaluation of position() on descendant axis
by Martin Gieseking 09 Nov '10

09 Nov '10

Hi, while playing around with BaseX, I stumbled over some weird results in conjunction with positional predicates on the descendant axis. As far as I can see, there seems to be a bug in the evaluation of function position(). Example: When I load the following XML document and evaluate the path expression /descendant::c[1], both c element nodes are returned, but only the first one is expected. So, currently the result is identical to that of //c[1]. <a> <c/> <c/> </a> Best regards, Martin

BaseX 6.3.1
by Christian Grün 08 Nov '10

08 Nov '10

Hi all, things are moving forward again; the latest minor release of BaseX 6.3.1 contains a bunch of improved features; we've revised our APIs, and we have added improved language support to XQuery Full Text. Next, we're doing our best to improve the availability of all BaseX features, many of which are just too hidden to be noticed by everyone, and to work on the documentation. Finally, we're glad to announce that we've successfully created the infrastructure to offer commercial requests and professional support on BaseX. The project itself will remain open source, of course. More is to come.. Here's the latest changelog (which is now available on the homepage as well): [ADD] Fulltext: Built-in support for Snowball, Wordnet, and Lucene stemmers [ADD] Fulltext: Internal German stemmer added [ADD] REST: support for hierarchical collections added; details will follow [ADD] REST/GET: bind parameter added to enable external variable bindings [ADD] REST/POST: <variable/> and <output/> elements added [ADD] APIs: bind(), execute() & info() added to query iterator [ADD] APIs: add() implemented for adding documents to existing databases [MOD] REST: start was simplified; just launch basex-api/etc/basexrest(.bat) [MOD] JAX-RX: latest version was moved to our BaseX SVN repository [MOD] Warning: start class BaseXWin was renamed to BaseXGUI [MOD] Work on the upcoming Windows installer [FIX] XQuery: improved handling of extended kind tests in sequence types [FIX] XQuery 3.0 functions (e.g. format-integer()) [FIX] XQuery Update, Namespaces, collections [FIX] GUI: realtime filtering Have fun, Christian ___________________________ Christian Grün University of Konstanz Department of Computer & Information Science D-78457 Konstanz, Germany Tel: +49-7531-88-4449, Fax: +49-7531-88-3577 http://www.inf.uni-konstanz.de/~gruen

REST interface does not support/comply-with 'default' XForms mediatype (application/xml) for PUT, POST (and possibly others)
by Mahender Didwania 04 Nov '10

04 Nov '10

If I attempt to create a resource using PUT or POST using XForms Submission mechanism, it fails because by default, XForms Submissions use application/xml as content-type, but BaseX expects text/xml. BaseX actually fails the request if given application/xml! Would like BaseX to support XForms - XForms default submission mediatypes are listed at http://www.w3.org/TR/xforms11/#submit-options Thanks.

Re: [basex-talk] REST questions
by Christian Grün 31 Oct '10

31 Oct '10

Hi Nigel, thanks for the detailed wish list. First of all, I'd advise to follow the steps described at http://basex.org/rest. This tutorial seems to be well accepted by our users. As you might have seen, it's still based on version 6.1, so it will be updated with the next official release. > 1. Start the REST service. > ========================== > > When I start the BaseX server by doing; > > C:\>java -cp basex-6.3.jar org.basex.BaseXServer -s > > does that also start the REST service? No; the Jetty server and some other external libraries are needed to run the REST service; these aren't included in the default distribution of BaseX (which doesn't rely on any external packages), but found in the basex-api.zip package instead. We'll soon automatize the process of including a runnable REST/JaxRx version in each minor release. > 2. Test the rest service. > ========================= > > How can I test if the REST service is running on localhost? Pointing a > browser at http://localhost:8984/basex/jax-rx/ returns the following error; If you follow the tutorial, you shouldn't encounter any problems; just tell us if you need an updated, precompiled version of the basex-api.zip distribution package. Note, next, that all browsers will give you different results. Some browsers will display the result as XML, whereas others (such as Chrome) doesn't show anything. You might try tools like 'curl' to get all output printed on screen. > Connection refused: connect This indicates that the web server hasn't been started; see 1. > 3. Using REST. > ============== > How do I create a restful interface? Say I want to create a REST API that > simply does the following; > > An HTTP GET to locahost:8984/basex/jax-rx/foo/ returns <hello/> > An HTTP GET to locahost:8984/basex/jax-rx/bar/ returns <world/> Hm, I'm not sure what you want to do here. If your database "foo" includes the document "<hello/>", you'll indeed get this result. Note that the next version of REST/JaxRx, on which we're currently working, will support hierarchical paths; i.e., you'll be able to watch parts of a database by specifying the correspondent collection path. An example: locahost:8984/basex/jax-rx/YourDB/path/to/relevant/documents?query=query/to/be/executed Hope thie helps, Christian
