deploy and undeploy a gbean

Hello,

I'm trying to write a GBean which dynamically deploys and undeploys  
other GBeans. My first thought about this task was to get a list of  
all running modules from which I could decide which to undeploy.

String uri = "deployer:geronimo:inVM";
String username = "system";
String password = "manager";
		
dManager = dFactoryMgr.getDeploymentManager(uri, username, password);

System.out.println("Targets:");
Target[] targets = dManager.getTargets();		
for(Target t : targets) {
	System.out.println(t);
}

System.out.println("Modules:");
TargetModuleID[] moduleIDs = dManager.getRunningModules(null, targets);
			
for(TargetModuleID m : moduleIDs) {
	System.out.println(m);
}


With the code above I tried to accomplish my goal. But if I run this  
one I get the following exception:

Is there another way to deploy/undeploy GBeans via another GBean?

I even tried it with another URI (String uri =  
"deployer:geronimo:jmx:rmi://localhost/jndi/rmi:/JMXConnector";) but  
with that I still got a worse result.

Since I've the package org.apache.xbean.naming in my classpath I  
don't no why geronimo can't instantiate a class of them.

So has anyone an idea how to solve a deply/undeploy task?

Best regards,
Stefan

Ops, I thought the dev-list is for developing stuff. I will close  
this thread an "reopen" it under the user list. Please ignore this  
one ;-)

Hi,

I won't help you with it, but perhaps point in the right direction.
CCE is when a class is in two classloaders. I think the proper way is
to declare a dependency on GBeanDeployer in your gbean descriptor. I
have never done it before so it's way the answer is wacky.

See var/config/config.xml for references how to wire gbeans (and await
others' responses to get the real answer ;-))

Don't do that. There're simpler ways, I guess. I'd rather see gbean
wiring used not Java Deployment API.

BTW, It's a user question so you'd be better off sending it to the
user mailing list - user@geronimo.apache.org (see
http://geronimo.apache.org/mailing-lists.html).

Jacek
