An exception for MLET. What is wrong?

[arabinow]

I have the following code for MLET:

String pulsarName = "com.peerdirect.rmapplications.master.jmx.PulsarModel" ;
MLet mlet = new MLet();
//Object pulsar = Class.forName (pulsarName).newInstance();
String name = myMBeanServer.getDefaultDomain() + ":type=" + pulsarName;
name = "type:name=mlet";
System.out.println ("MLET: " + name);
ObjectName objName = new ObjectName(name);
myMBeanServer.registerMBean (mlet, objName);
//final String MLET_URL = "file:./output/etc/test/compliance/loading/BasicConfig.mlet";
//final String MLET_URL = "C:\\aa\\BasicConfig.mlet";
final String MLET_URL = "file:///C:/aa/BasicConfig.mlet";
try
{
DefaultLoaderRepository.loadClass (pulsarName);
System.out.println("Too bad");
}
catch (Exception ignored)
{}
myMBeanServer.invoke (objName, "getMBeansFromURL",
new Object[] { MLET_URL },
new String[] { String.class.getName() }
);

Also, I have the following MLET tag in my BasicConfig.mlet file:
<MLET CODE=com.peerdirect.rmapplications.master.jmx.PulsarModel
NAME="DefaultDomain:type=com.peerdirect.rmapplications.master.jmx.PulsarModel"
CODEBASE="file:///C:/build/GUI2/ram/run_agent"
ARCHIVE="PeerdirectMasterServerFull.jar"
>


I have the following exception:
Creating an instance of MasterAgent...
MLET: type:name=mlet
RuntimeMBeanException: RuntimeException in MBean operation 'getMBeansFromURL(,java.lang.String)'
Cause: java.lang.ClassCastException: org.jboss.mx.loading.UnifiedClassLoader

at com.peerdirect.rmapplications.agent.MasterAgent.(MasterAgent.java:5)
at com.peerdirect.rmapplications.agent.MasterAgent.main(MasterAgent.java:15)

At the same time my file C:/build/GUI2/ram/run_agent/PeerdirectMasterServerFull.jar contains file com\peerdirect\rmapplications\master\jmx\PilsarModel.class

What is wrong? Why am I getting the exception?

[arabinow]

I tried this thing under several different scenarion:

when my MBean is a Standard MBean

when my MBean is a Model MBean

The problem occured both times.
However, if I use Sun JMX implementation on the client (file jmxri.jar instead of jboss-jmx.jar) Standard MBean works correctly (while Model MBean still does not).

[arabinow]

When I use JBoss JMX implementation, I still have to use jmxtools.jar from Sun implementation, in order to have CommunicatorServer.class present in my jar file, correct?
Or is that a cause of the problem.
I use the following jars for client:
jboss-jmx.jar;jmxtools.jar;jbossall-client.jar;jboss-j2ee.jar;jnp-client.jar;jnet.jar;log4j.jar

which version are you using?
