Yes. I studied the "Dynamic AOP" chapter and looked into examples. I think these examples are running on ONE JVM. Let me clarify my previous question step by step. 1. Consider the client/server environment. 2. Suppose a class "A" be running on a server. Assume this class be prepared for the dynamic AOP. 3. In a client side, how can I load an aspect that will be woven with the class "A"? We need to access the running JVM on the server. I think the issue of my question is how to access and insert an aspect into a running JVM on a server. By the way, some examples use Java Debug Interface (JDI) to access a running JVM . Can I need to use the JDI ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080914#...
