I have very strange exception after starting using beans.xml
file in our EJB
and jar files.
We use JBoss7.1.1
release.
Our app
This is a known issue when using jersey. Try to add below option to your jvm, which will fix your issue. If you are running the jboss server from eclipse then add to the server runtime configuration. If you are starting the jboss from command prompt using standalone.bat then add the below option to standalone.conf.bat. Similarly if you are using *Nix then add to standalone.conf.
set "JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true"
