Java – JStack
When reviewing \ debugging a Java Application, one can try using “JStack”.
JStack principally displays the StackTrace for each thread in an Application.
Listed below are a few well written coverage of this important tool.

Couple of areas to keep in mind:
- On a Windows box running a 64-bit OS, you will not be able to “connect” to a 32-bit App running under WOW64.If you try to, you will get an error message similar to “Unable to attach to 32-bit process running under WOW64”
Hey i am actually trying to use the ATTACH API and am getting the error “unable to attach to 32-bit process running under wow64”. Is there a work-around for this?
Sorry I did not do any more research on a 64-bit.
It is a big to do for me — But, lately more work on Linux systems.
Thanks for posting.
