Hi,
I have the wierdest error. it goes as follows:
1) I'm using JBoss 3.2.6 (Tomcat 5)
2) I deploy my application in ear format.
3) I login to our central web page and click on a link to my web page.
4) My login is authenticated thru JAAS and I'm allowed access to my web page.
5) I redeploy my application in ear format (hot deploy)
6) close my browser, (so that there is no session pollution)
7) I login to our central web page and click on a link to my web page.
8) Then I get the following error:
WARN [FailoverUtil] The current resource caused a system exception. Will try
failover resource 2
java.lang.NullPointerException

Upon seing it had to do with the UnifiedClassLoader, I configured my
jboss-app.xml file to look as follows:
<?xml version="1.0"?>
<jboss-app>
<class-loading java2ClassLoadingCompliance="false">
<loader-repository>
za.co.santam.RISplitterWeb:loader=RISplitterWeb.ear
<loader-repository-config>
java2ParentDelegation=false
</loader-repository-config>
</loader-repository>
</class-loading>
</jboss-app>
However, even with this change this still seems to be a problem.
Does anyone have any suggestions or a possible solution for me?
Thanks,
Grant
