Cristiano Nicolai commented on TEIID-1324:
------------------------------------------

In fact, to have the Teiid JOPR plugin up and running two fixes are required, put the Teiid client jar in the classpath and the second one is the missing jboss jar that I agree that if the solution that I showed is the only way to fixed it, a bug must be open with the RHQ project. The only point is that I think that cant be treated as a bug by them, maybe a feature request, because the jboss-as plugin is working properly.

> Basically the missing jar is jboss-metatype.jar.
> I tried some classloader configuration including the missing jar in teiid-console-7.2.0.Beta1.jar/lib, but as it has dependent classes (jboss-managed.jar) that are loaded in jboss-as-5 RHQ plugin I couldn't find any solution without changing the jboss-as-5 code. Probably some sync with RHQ guys is needed because jboss-managed.jar depends on jboss-metatype.jar.
> My workaround for this was a code change in ApplicationServerDiscoveryComponent to include the required jar from the AS installation.
> private static final List<String> CLIENT_JARS = Arrays.asList(
>         // NOTE: The jbossall-client.jar aggregates a whole bunch of other jars from the client dir via its

>         "client/jbossall-client.jar",

>         "lib/jboss-reflect.jar",
>         "lib/jboss-dependency.jar"
>     );
> Fixing this class dependency the plugin start to require some Teiid client classes and to solve this I just copy the teiid-7.2.0.Beta1-client.jar to teiid-console-7.2.0.Beta1.jar/lib and redeploy the plugin.
