JBoss 4.2 load javax.xml.parsers.DocumentBuilderFactory from xmlparserv2.jar?

Question

I'm using JBoss 4.2 and jdk6.

How can i only load javax.xml.parsers.DocumentBuilderFactory from xmlparserv2.jar in my webapp ?

When i used -verbose:class, javax.xml.parsers.DocumentBuilderFactory loaded by jdk6 :

[Loaded javax.xml.parsers.DocumentBuilderFactory from C:\Program Files (x86)\Java\jdk1.6.0_21\jre\lib\rt.jar]

and by xmlparserv2.jar

I have the following trace when Spring load. I use Spring core 3.1.3.

INFO  [STDOUT] ERROR [main] (ContextLoader.java:307) - Context initialization failed

MyEar
  - lib
      ...
      xmlparserv2.jar
      ...
  - META-INF
      application.xml
      jboss-app.xml
  + mywar.war

I have nothing in the WEB-INF/lib from the war.
I can't remove xmlparserv2.jar because i need the oracle implementation of XMLNode in some jar.

Are there solutions without migrate JBoss to an older version ?

Answer 1

Could you use a system property to force the specific Factory you want?

Quoting info from here...

You can also set a system property in your code: System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "new-factory") For example, if you are using the xerces parser, then new-factory is replaced by jorg.apache.xerces.jaxp.DocumentBuilderFactoryImpl.
