Frustration has set in. Need assistance.

[cbroussard]

Hello All,

I was hoping somebody could point me in a direction of sanity

I've been a jboss 2,3,4 user.  After taking a few years off of development I'm getting back into jboss 6 and hitting some roadblocks (Either cause I don't remember or the behavior has changed).

This is what I'm trying to do.

I have written a custom valve that I have chained in the tomcat jboss-web.sar.  I'm able to access/execute that fine.  During that invocation I attempt to make a jmx call into an mbean.  I'm getting a class not found exception for the jnp name factory during this

MBeanServerConnection server = (MBeanServerConnection)new InitialContext().lookup("jmx/rmi/RMIAdaptor");

I've attempted to copy the client/jnp-client.jar in literally every directory location I could find to attempt to add it to the classpath.  But I haven't been able to find it.  I've even tried to copy the entire client/*.jar files around that just causes havoc.  What's the easiest way to get this to work?  I will also be doing EJB3 remote calls from Web to Ear and from Ear to Ear.  I'm getting concerned that I won't be able to do lookups on that either.

I was able to write a lot of business code in a short period of time, but have completely hit this roadblock for a couple days.   Can somebody please assist?

Thanks In Advance!

Chris

Please post the entire exception stacktrace. Also which exact version of JBoss AS6 are you using?

P.S: AS6 and previous versions of JBoss AS are no longer in development. AS7 is the latest version available and actively developed. 7.1.0.Final is being released very soon.

Hi Jaikiran,

Thank you for taking the time to respond.  Here's the information you requested:

   <classpath codebase="${jboss.common.lib.url}" archives="*"/>

   <classpath codebase="${jboss.server.lib.url}/lightedworks" archives="*"/>

inside lightedworks folder i have a couple jars i've created that house the Valve Code and jmx bindings code.  This is the location that I attempted to put all the client jars.

Any ideas?

Thanks,

Chris

[edit]

ps.. forgot to say.. i'm on JBossAS [6.0.0.Final "Neo"]

Is that exception on the server side? Also, I think that's not the complete stacktrace, can you please post the full one.

I don't think you would need all that. I would recommend that you not change the jboss-service.xml and instead just place your jars in the JBOSS_HOME/server/<servername>/lib folder directly or maybe in JBOSS_HOME/common/lib depending on how you want to distribute it.

The exception happens from the catalina valve.  I'm trying to make jmx call to retrieve some configuration data out of the management bean.

any ideas?

again much appreciation for your time and effort on this.

It is a strange behaviour.

Anyway I think you don't need to make a JNDI lookup to get local MBeanServerConnection.

Try this:

MBeanServerConnection mbsc = ManagementFactory.getPlatformMBeanServer();

Hi Fabrizio!

That worked!!  I got further... Still trying to isolate the container error... But when you said 'It is a strange behavior' you are talking about ClassNotFoundException or something else?

Thanks!

Chris

[fabrizio.benedetti]

Happy for you.

Yes, about ClassNotFoundException. Class org.jnp.interfaces.NamingContextFactory should be always available, also for tomcat valves. Problably your valve runs in a different classloader.

I would follow Jaikiran's advice,  with a clean jboss installation and putting your jars only in JBOSS_HOME/server/<servername>/lib folder.

Anyway JNDI lookup is needed only when you want to retrieve remote MBeanServerConnection.
