Hi,
I am writing a certain plug-in where I have to invoke a method of a MBean
running on a JMX server. I added the .jar(where the .class files are in)
of that MBean as external jars to my project. There is no problem with
compiling my code and invoking the method; however, I get an error at
runtime back because the return type of the method invoked can't be found
although the .class is in the jar file included. It would be great if
anyone can help ASAP .Here is my code snippet followed by the error
message:
System.setSecurityManager(new RMISecurityManager());
Properties p = System.getProperties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.rmi.registry.RegistryContextFactory");
p.put(Context.PROVIDER_URL, "rmi://localhost:1099");
JRMPConnector connector = new JRMPConnector();
String jndiName = "jrmp";
connector.connect(jndiName, p);
// Get the remote MBeanServer from the connector
// And use it as if it is an MBeanServer
RemoteMBeanServer remoteServer = connector.getRemoteMBeanServer();
ObjectName objName = new ObjectName("de.bmw.VCM:type=management");
try{
Object result =
remoteServer.invoke(objName,"getUnits",new Object[]{new Integer(1)},new
String[]{"java.lang.Integer"});
}catch (javax.management.RuntimeMBeanException rme) {
if (rme.getTargetException() != null) {
rme.getTargetException().printStackTrace();
} else {
rme.printStackTrace();
}
}
the "result" return object is from type "de.bmw.ECU" , the .class of that
class happens to be in the external jar included in the project. Here is
the error stack:
ava.rmi.UnmarshalException: Exception while reading result; nested
exception is:

How about the Eclipse class loader issue then? It is described in FAQ. One
has to set up classloader explicitely in some cases.
