denny Valliant commented on JBAS-3248:
--------------------------------------

You can just delete the xercesImpl jar in the jasperserver/WEB-INF/lib folder and it will start fine.  Haven't done extensive testing with XML stuff to make sure there isn't something broken deep inside, but everything seems to work just dandy.

> I have an application (.war file) that uses a lib called xerces.jar located at .war /WEB-INF/lib directory. I run JBoss in cluster mode. So, after deploy, when I run my application, I got an exception with the xml libs. I guess it's a classloader problem. MY application tries to use the JBoss xml classes intead of it's own. I discovered the problem was with the xerces.jar and xercesImpl.jar because I deleted the line below from the <JBOSS_HOME>/bin/run.sh:
> -Djava.endorsed.dirs=...
> I searched for a solution and discovered jdk versions before 1.5 have a bug with xml, so I tried the solution above and all worked fine. Now my application use it's own xerces instead of JBoss xerces.
> I think my solution is a workaround. I would like to know if there is a better way to solve this problem. Is there ?
> The exception is below.
