How to Force Thread Dump in Eclipse?

Question

I'm launching a Weblogic application inside Eclipse via the BEA Weblogic Server v9.2 runtime environment. If this were running straight from the command-line, I'd do a ctrl-BREAK to force a thread dump. Is there a way to do it in Eclipse?

Solution 1

Indeed (thanks VonC to point to the SO thread), Dustin, in a comment to his message, points to jstack.

I have run a little Java application (with GUI) in Eclipse, I can see the related javaw.exe in Windows' process manager and its PID, 7088 (it is even simpler in Unix, of course).

If I type at a command prompt jstack 7088, I have the wanted stack dump per thread.
Cool.

Would be better if we could do that directly from Eclipse, but that's already useful as is.

You can do it when you are in debug mode: go to the debug view in the debug perspective, click on the process you have launched and click on pause, you will get a graphical stack of all your processes.

Note : this also works when using remote debugging, you do not need to launch weblogic from eclipse, you can launch it on its own, open the debugging ports and create a "remote java application debug configuration" for it.

Eclipse Wiki: How to Report a Deadlock lists all possible options of creating a thread dump in Eclipse. Depending on the concrete situation, one or the other may work better -- my personal favorite on Windows is the Adaptj Stacktrace tool.

Solution 5

StackTrace is another option that you could try. From the features:

Thread dump for Java processes running as a Windows service (like Tomcat, for example), started with javaw.exe, applets running inside any browser or JVMs embedded inside another process. StackTrace works on Windows, Linux and Mac OS X.
