jbossall-client.jar causes exception IncompatibleClassChange

[mark_man]

JBoss 4.2.1

I am deploying a very minimal JSF application. I have jbossall-client.jar in the lib directory of the war file. Upon deployment I get the following exception:

2007-10-12 22:06:40,397 INFO [STDOUT] 22:06:40,390 ERROR [[/spokes]] Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
java.lang.IncompatibleClassChangeError
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:627)


The previous version I was using JBoss 4.0.2 did not have this issue. Any thoughts as to why this is occuring?

Thank you for your help,
Mark

Why are you packaging that JBoss specific jar in your application? It's already present in JBoss' lib folder. You dont have to package that in your application. Packaging that in the application can lead to errors like these.
