Validation Module
by Seenivasan Gunabalan 25 Jun '12

25 Jun '12

Hi all, I am trying to validate an incoming xml post message against an xsd stored inside the basex. But I am getting this error [FODC0002] Resource 'sampledb/xsd/match.xsd' does not exist. I am sure the path is correct and the xsd file exists there. May I know where I am going wrong? try { let $doc := |<simple:||root| |xmlns:simple=||'http://basex.org/simple'||/>| return validate:xsd($doc,'sampledb/xsd/match.xsd') } catch BXVA0001 { 'Validation failed.' } Thanks in advance.

Hi All, I builded a kind of connection pool using BaseXClient.java class, I simulated several users trying insert documents in BaseX, the result was a disaster. ERROR: data.BaseXDataAccess - Error closing db java.io.IOException: Stopped at line 1, column 19: Unknown command: 1340477810253095000. Try HELP. at data.BaseXClient.execute(BaseXClient.java:99) at data.BaseXClient.execute(BaseXClient.java:110) at data.BaseXDataAccess.save(BaseXDataAccess.java:169) at data.TestInsert$Insert.run(TestInsert.java:88) at java.lang.Thread.run(Thread.java:680) Exception in thread "Thread-1" java.lang.RuntimeException: java.io.IOException: at data.BaseXDataAccess.save(BaseXDataAccess.java:164) at data.TestInsert$Insert.run(TestInsert.java:88)ERROR: com.xftec.hyperion.data.BaseXDataAccess - Error closing db I started several threads each one takes a BaseXClient connection and as soon as it finishs its job BaseXClient is put in a queue again to be took by other thread.

deadlock in BaseXServer 6.2.7
by Godmar Back 23 Jun '12

23 Jun '12

Hi, we're observing that our BaseXServer 6.2.7 deadlocks. The stack traces are here: http://top.cs.vt.edu/~gback/bx/deadlock-6.2.7/basex-deadlock.txt Could you take a look to see if these ring any bells? Has this problem been addressed in a more recent version? - Godmar

safe to upgrade from 6.6.3 SNAPSHOT to 7.3?
by Godmar Back 23 Jun '12

23 Jun '12

Also - is it safe to upgrade to 7.3? We now have production data (or at least the beginnings thereof) in our BaseXData directory. Is the binary format still the same, or do we need to export/reimport the XML? - Godmar

Install issues
by André Milton 20 Jun '12

20 Jun '12

Hi guys, I'm having a hell of a time trying to install BaseX on CentOS with Yum. It says I'm missing xml-commons-resolver 1.2 and lucene-contrib: Resolving Dependencies --> Running transaction check ---> Package basex.noarch 0:7.2.1-3.2 set to be updated --> Processing Dependency: xml-commons-resolver = 1.2 for package: basex --> Processing Dependency: lucene-contrib for package: basex --> Processing Dependency: jline for package: basex --> Running transaction check ---> Package basex.noarch 0:7.2.1-3.2 set to be updated --> Processing Dependency: xml-commons-resolver = 1.2 for package: basex --> Processing Dependency: lucene-contrib for package: basex ---> Package jline.noarch 0:0.9.94-0.9.el5_6 set to be updated --> Finished Dependency Resolution basex-7.2.1-3.2.noarch from home_basex_opensuse has depsolving problems --> Missing Dependency: xml-commons-resolver = 1.2 is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) basex-7.2.1-3.2.noarch from home_basex_opensuse has depsolving problems --> Missing Dependency: lucene-contrib is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) Error: Missing Dependency: xml-commons-resolver = 1.2 is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) Error: Missing Dependency: lucene-contrib is needed by package basex-7.2.1-3.2.noarch (home_basex_opensuse) I've downloaded both and added them to a CLASSPATH but the install script still complains. What step have I missed? Do I also need to add them to my PATH (would prefer not to)? Thanks! a+,a.

Java method signature: no empty sequence allowed
by Mattijs Ugen 20 Jun '12

20 Jun '12

Dear all, Calling methods from a QueryModule works nicely, yet I can't seem to get a particular method signature to work from XQuery. The function in question should be passed a string and the result of a path expression, yielding attribute values as strings. For example: ns:method($value, $context/ancestor-or-self::*/@some-attr/string()) Intuitively, I figure the signature for this method in the QueryModule should be: public String method(Str previous, Value additionals) { ... However, trying to use this method with BaseX won't work. The query editor accepts the syntax, but states "PXML:combine method: no empty sequence allowed". Changing the signature to Seq, ItemSeq or even Empty changes nothing; it keeps telling me (I think) the expression *could* yield an empty sequence and the method does not support it (even tho Empty is a valid value for Value, is it not?). How would I define my method so that BaseX will accept it? Kind regards, Mattijs Ugen
