如何使用JavaSnoop附加到Java小程序？

Question

I am troubleshooting a poorly documented Java applet and would like to attach to it with JavaSnoop to actually see what arguments are being passed into certain method calls. I can successfully attach to a locally run Java application in a jar file, but cannot get attachment to an applet to work.

I have been assuming you click "Attach & Snoop Process...", run the applet, and then should see that applet's process in the list. I get nothing in this list when I run any applet. Am I missing a step?

I am also open to alternative ways to hook the method call to read its arguments.

Answer 1

..alternative ways to hook the method call to read its arguments.

Extend the applet and method. Embed the extended applet. In the extended method, log the arguments.
