Accessing basex from rest and from java api
by Henrique Oliveira 04 Jun '12

04 Jun '12

Hi All, Is possible to access BaseX from REST and Java API at the same time, same dbpath? I deployed BaseX.war in Jetty server, it is running on port 8080, I tried to connect using Java API without success. it seems is running on 1984 port too.

Re: [basex-talk] Deleting one of many resources at the same path (sorry for hoging the email distribution list)
by Anupam Bakshi 01 Jun '12

01 Jun '12

Hi Dimitar, Since collections are sequences, can I use [1] or [last()] to specify which one to delete? As per my requirement, I need to be able to delete older resources after some processing (data consolidation). Thanks for your help. Best regards, Anupam

However, when I do the following, I get the XML content from the first file. XQUERY db:open("project1", "resultset1.xml") What is the way to get the second XML file? Thanks for your help. Anupam

Attribute indexing
by Alex Markin 01 Jun '12

01 Jun '12

Hello, BaseX team. I have a question about attribute indexing in basex. For example i have an xml file (in attachement). I execute the following sequence of commands: $ ./basex -Vc"SET ATTRINDEX true;SET UPDINDEX true;CREATE DB test" ATTRINDEX: ON UPDINDEX: ON Database 'test' created in 90.22 ms. $ ./basex -Vc"OPEN test;CREATE INDEX ATTRIBUTE;OPTIMIZE" Database 'test' was opened in 70.03 ms. Index 'ATTRIBUTE' created in 39.48 ms. Database 'test' was optimized in 31.14 ms. $ ./basex -Vq"index:attributes(\"test\")" <value count="70"> 0)(286, 1)[_ 4¦°䐪J'(*¤#(1, 1)</value> <value count="3">86, 1)[_ 4¦°䐪J'(*¤#(1, 1)(1, 12)-fi</value> <value count="1">/home/alex/tmp/erts/ntbuild.E</value> ... Out of Main Memory. There are no indices, given in first lines and some strange "Out of memory". What's wrong with this way of getting indices and how to fix it? Markin Alex

List of all resources in XQuery?
by Anupam Bakshi 31 May '12

31 May '12

Hello all, In XQuery I can use doc('resource_path') to open a resource from the baseX database but is there a way to list all available resources in the database? In other words, what is the equivalent of "LIST database_name" in XQuery? Thanks for your help. Anupam

Hi, Can I use a Context object to create more than one database? For example: new CreateDB("db1","c:\db1").execute(this.Context); new CreateDB("db2","c:\db2").execute(this.Context); Thanks. Cheers, An

Problem with copy-namespaces declaration
by Hans-Juergen Rennau 30 May '12

30 May '12

Hello, I observed a little problem concerning the interpretation of a copy-namespaces declaration. More specifically, the value no-preserve is correctly observed if the source is constructed within the query, but not if the source is read from a file. Example query: declare copy-namespaces no-preserve, inherit; let $in := <data xmlns:r="http://example.com"><elem/></data> return <result>{$in/elem, doc('problem-doc.xml')//elem}</result> where "problem-doc.xml" contains exactly the same document as the query (<data xmlns:r="http://example.com"><elem/></data>) Output: <result> <elem/> <elem xmlns:r="http://example.com"/> </result> Kind regards, Hans-Juergen

Question about Servlet accessing BaseX
by Anupam Bakshi 29 May '12

29 May '12

Hello, I'm creating my first BaseX based app and have a few questions about the best possible way to architect it around BaseX. I need to use BaseX as a service in a Tomcat container on the same server machine. I have the following doubts: 1. I need to validate the XML coming into the database and do XSLT transformation. Should this be done in a servlet that connects to BaseX? 2. If so, should the servlet use REST too, or is there a better way for direct connection? 3. Since BaseX is running in Tomcat context, is it possible to access it using a local client on the server machine- for debug etc on the server machine? Thank you for your help. Best regards, Anupam

Who is using...?
by Christian Grün 28 May '12

28 May '12

Hi all, we are interested in your opinion! As one of our main focus is to keep BaseX small and cute (..sad but true: the BaseX core library already exceeds 2mb.. ;), we're currently contemplating the removal of two existing BaseX features, namely.. 1) the BaseXHTTP client mode (flag -c). Currently, we offer three operation modes: default, local, and client [1]. In client mode, all requests are supposed to be passed on to yet another BaseX server instance. Currently, however, WebDAV is the only service which is 100% compatible with this mode, while RESTXQ isn't tailored at all to handle remote database requests. Instead, we are contemplating on adding a light-weight XQuery Client API Module, which can then be used to explicitly address remote BaseX instances from within XQuery whenever databases are not stored locally anyway. 2) the current ZIP Module. The functionality won't disappear, though: we will replace it with a new, more flexible proposal specified by Matthias Branter (28msec) and me [2]. In a nutshell: who of you is using either 1) or 2) and would run into big troubles if those features were ousted and replaced with the approaches we believe are more promising for future development? Thanks as usual for your feedback, either to the list (preferred) or in private, Christian [1] http://docs.basex.org/wiki/Startup_Options#BaseX_HTTP_Server [2] http://spex.basex.org/index.php?title=ZIP_Module

bindings command in GUI not functioning as expected
by Brown, David (SSC-A) 28 May '12

28 May '12

Running 7.2.2 beta The standalone interface takes the following input: "set bindings $date=20120507, $envir=PRD_Win" and returns "bindings: $date=20120507, $envir=PRD_Win" The GUI interface on the command bar takes the following input: "set bindings $date=20120507" and returns "bindings: $date=20120507" "set bindings $date=20120507, $envir=PRD_Win" and returns "Error: Syntax: SET [option] ([value]) Set global options." This is a problem if you have more than one binding required. v/r, David Brown Fully Qualified Navy Certification Agent LSS Certified Blackbelt, CISSP, NSA-IAM/IEM, MSCIS SPAWARSYSCEN ATLANTIC ISS LOB SSC Lead Email: <mailto:david.k.brown1@navy.mil> david.k.brown1(a)navy.mil Phone: 843.218.6227 DSN: 588.6227 Fax: 843.218.5461 "Let us not look back in anger or forward in fear, but around in awareness."
