Ramesh Reddy commented on TEIID-1324:
-------------------------------------

This is a one of the core jars from the JBoss AS. This should have been available in the higher order classloader already. This is available in JBoss AS 5.1.0, the questions is why it is not in the EAP 5.1

> 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
>         // MANIFEST.MF Class-Path.
>         "client/jbossall-client.jar",
>         "client/trove.jar",
>         "client/javassist.jar",
>         "common/lib/jboss-security-aspects.jar",

>         "lib/jboss-metatype.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.
