tell you, that your SLSB is beeing called. The rest is irrelvant noise.

Then there is some problem in native code. This issue is probably not related to WS

My Jboss is version 4.0.2, before I was using 4.0.1 and it was working well. I think I made the same configuration, but got the exceptions as above.

[kalparser]

I fixed the problem by Setting the UseJbossWebLoader back to true:

attribute name="UseJBossWebLoader">true

which is located at: jboss-4.0.2/server/default/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml

This is happening because util.jar is defined in the EAR, and some of the WEB classes (Servlets) are using classes defined at the EAR level.

[jason.greene]

A JBossWebLoader value of false will create a new classloader per war, but that classloader should still delegate to the parent class loader (in your case the ear classloader). The only thing that changes when you set this to true is that classes in your war are added to the ear.

So, only if you had ejb's that depeneded on classes in your war would require you to set JBossWebLoader to true.

There was a bug in 4.0.2RC1 that would prevent this from working properly, but it was fixed in the 4.0.2 final release. Are you running the 4.0.2 final release?
