Hi,

I tried to migrate our server app from as 4 to 7. I came into the problem that resteasy could not deploy. Without full understanding of the new as7 architecture and structure I tried to fix it in the dependency section of the modules.xml of org.jboss.resteasy.resteasy-jaxrs using: <module name="org.apache.log4j"/>.

It worked. See the stacktrace (without the fix):
