Hi,

I'm relatively new to JBoss, and I've been having 'stale class' problems, i.e. the war I deployed a couple of days ago executes but apparently successful new deploys are ignored.

Reboot of JBoss does not fix the problem, but re-installing JBoss does. I have been thru the re-install cycle three times now, as distinct from many jboss restrarts during the servlet deploy cycle, so I am sure re-install is necessary to fix the problem, for whatever reason.

The war is unpacked into jboss, .../tmp/deploy/ but its classes were apparently not visible to the appropriate classloader

The startup console log has the following warning lines, which I suspect are related to the problem, because they are about Tomcat and classloading, where my problems show up.

09:28:26,843 WARN [EmbeddedTomcatService] Unable to invoke setDelegate on class loader:org.jboss.web.tomcat.tc4.WebCtxLoader$ENCLoader@719f1f

09:28:38,234 WARN [EmbeddedTomcatService] Unable to invoke setDelegate on class loader:org.jboss.web.tomcat.tc4.WebCtxLoader$ENCLoader@84f566


What do these warnings mean, and how do I get them to go away ?

Info:
1) I have not made any configuration changes to JBoss,
2) I deploy by copying a war file into default/deploy/, and
3) My environment is as follows:
