Ted Jones commented on TEIID-1324:
----------------------------------
Right... "the method "getAdditionalClasspathUrls" needs to be overloaded
with the this jboss-reflect.jar". That's the fix (for now) that I was referring
to in my previous comment. I guess I over-explained the issue ;-).
The RHQ team recognizes the jboss-reflect.jar needs to be in the classloader of the
JBossAS5 plugin and are adding it for the next RHQ release.
"More over these should be in the core classpath that JON creates, there is no reason
each individual plugin needs to create their own classloader when these are core
libraries. " They do not have the full set of JBoss jars in the JBossAS that JON
uses, so the JON classpath can't load them. This is because different versions of
JBossAS may be monitored by the JON Server/Agents
Deploy JOPR Plugin on JON/RHQ

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-managed.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.
