Debugger "Drop to frame" [message #143552]

In VisualAge for Java, there was a debugging feature "drop to frame",
which allowed you to restart execution at a higher level in the stack,
for instance, to call the same method you are in again, possibly after
changing some parameters or variables. Is there any similar
functionality in Eclipse?

Thanks!

Yes. It is called "Drop to Frame" :-)
You select the stack frame you are interested in, right click>Drop To Frame

It requires a VM that supports this feature.

Full details are at:

Gee, how'd they come up with THAT name?!? ;-) Thanks a bunch Darin! I am
actually using WSAD 5.1.1, and this feature does not show up. So I guess
that means that the JDK 1.4.1 that is supplied with WSAD doesn't support it.

Correct.
If the VM responds negatively to our requests for its level of support, we
do not show the action.

I actually can get "drop to frame" to work for a simple Java program, so
the JVM definitely supports it. But I can't get it to appear on my menu
for any of my J2EE applications running in the WAS 5.1 WTE.

"drop to frame" does not work when the drop goes to or across a native
frame (due to the way the operation is spec'ed). For example, you can't
drop a program's main method, since it is called from native code.
