Hi all,
yes, I am a newbie to jboss. I have worked quite a while using tomcat and developped spring and struts2 applications. Now I started to learn more about hibernate and changed to jboss as ver 7.
I really thought I could just copy my old apps from tomcat webapps directory to jboss as standalone/deployments directory and everything would run fine. How could I be so optimistic!! :-))

I downloaded jboss-as-helloworld examples and they are running fine, so I think in principle everything is ok with my installation. It seems jboss cannot find the starting classes within the wars, but why and what can I do???
Take a look at my jboss log out, somewhere after deploying successfully my helloworld examples:

I can see that there is a difference in the path to the class IterationTag, but why does it work on tomcat and not in jboss. I thought I was independant from the server, if I build a war file.
Any ideas??
Little bit confused.
