We never saw this in AS 5.x. I was able to get past the exception by adding JBOSS_HOME/lib/jboss-classpool.jar and JBOSS_HOME/lib/jboss-classpool-scoped.jar to the RHQ Agent's classpath. So these two jars are now apparently required in the client classpath for the following basic JNP based lookup of the ProfileService to work: Properties env = new Properties(); env.setProperty(Context.PROVIDER_URL, "jnp://127.0.0.1:1099/"); // Always use the non-login context factory, since we'll use JAAS for authentication if a username/password was // provided. env.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); InitialContext initialContext; try initialContext = new InitialContext(env); } catch (NamingException e) { throw new RuntimeException("Failed to create JNDI InitialContext.", e); } ProfileService profileService = (ProfileService)initialContext.lookup("ProfileService"); Since this is the case, I think these two jars should be copied to JBOSS_HOME/client/ and also included in JBOSS_HOME/client/jbossall-client.jar's MANIFEST.MF Class-Path, to emphasize that they are needed for client connections and so that existing client code that uses jbossall-client.jar will not have to be updated to also include these two jars. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
