JBoss+JDK1.4+Xerces

[jova73]

Hi,
I'm running JBoss 3.0.3 with JDK 1.4 which comes with Crimson as XML parser but I want to configure JBoss to use Xerces so:
- I modified the run.bat script to set the relevant JAXP properties
set JAXP=-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
set JAXP=%JAXP% -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl
set JAVA_OPTS=%JAVA_OPTS% -Dprogram.name=%PROGNAME% %JAXP%
...

- then I put xerces.jar in JBOSS_HOME\lib

- then I've started JBoss but I get the following error

18:50:05,198 INFO [MainDeployer] Starting deployment of package: file:/C:/Java/
jboss-3.0.3_tomcat-4.0.5/server/default/conf/jboss-service.xml

umentBuilderFactoryImpl not found

Then I modified the classpath adding xerces.jar and now it's OK.
Can somebody tell me the reason?
Why the problem does not arise if I don't set JAXP properties? I think that JBoss has to find the right parser via JAXP even if I don't set the properties, or am i wrong?


Thank you very much in advance,
Andrea

I attempted the same solution and it doesn't work for me.

No matter what I do to override the default implementation for the DocumentBuilderFactory, it uses crimson instead of xerces.

I also tried defining a jaxp.properties in the jre/lib directory and it doesn't work.

Any ideas?

Does anyone know the solution for this. I am stuck on this for 3 days now.
Thanks

u shud be using the xerces jars that are located in the jboss_instance/lib/endorsed dirs

pass a system property to the JDK as follows

java -Djava.endorsed.dirs=<location of the lib/endorsed dir>

This will use the Xerces parser. More info can be had by looking at how JBoss does this in the run.bat/run.sh scripts.
