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.
