Is it safe to update xalan, xercesImpl and xml-apis jar file

[fredrik_is]

Hi!
I am writing an application that uses Xalans XSLTC package. When testing outside JBoss I am using the latest jars from Xalan's web site, put in the $JAVA_HOME/jre/lib/endorsed directory. This I do because the jars that comes along in the J2SDK 1.4.2_06 are not working correctly.

Now I want to deploy this on a test server running JBoss 3.2.6.
I have noticed that the jars I need are also included in the JBoss distribution. However, the xsltc package is missing in $JBOSS_HOME/server/default/lib/xalan.jar.

Is it safe to update the jar files xercesImpl.jar, xml-apis.jar and xalan.jar on the server, and where should i put them? Should I replace the ones in the JBoss distribution, or should I place them in the $JAVA_HOME/jre/lib/endorsed directory on the server?

Regards,
Fredrik Israelsson

Hi,
if you want save, the best way (IMO) is to put all in an EAR-File.
So your application work with the necassary XSLT and JBoss and other applications in the same JBoss AS runs with different..

I have already tried that.
I put the three jars in my .ear file, and declared them as java modules in the ear's META-INF/application.xml, as I do with several other libraries used, but it does not work. I get the same error as I get when running with the old jars only.

One thing you can try (if you are using jboss-3.2.5 or above) is set the isolated property on EARDeployer to true so that your EAR has a scoped classloader. If you are using a earlier version, then you can always set scoped class loading for your ear using jboss-app.xml. Check the jboss docs for Scoped EAR Loading.
