Re: remote method calling JMX 1.0

Hi Simon,
Thank you for you reply.
I have once more query on this same topic.
Remote method calling is possible using XML-RPC communication. Through
Apache's xmlrpc-1.2-b1.jar we can invoke a method which is in remote
class.Shall we use the same XML-RPC communication to invoke the remote
mbean(mbean in different server) ?

thanks again,
Rajesh.


Thanks
