Debug Duplicate Window [message #201872]

I am a bit confused. I am using Eclipse version 3.2 and have been using
it for some time but something must have changed and I'm not sure what.
When I enter into debug mode and my code hits a break point it opens a
second copy of the code (same exact code) that allows me to step through
it but I cannot make any changes to the code or even add break points. I
still have the editable code in a different window.

Thanks,
Ben

Sounds like it is loading the class from a jar file somewhere rather than
from your editable copy. Did your classpath change, or did the class get
added to a jar file on the classpath?

I have yet to create a jar file for this application and am only running
it out fo the Eclipse workspace for now. In windows explorer I checked
and the only class files are in the ..\build\classes\org\database\schema
directory that I would expect them in. I also checked the properties on
the proejct and did not see any reference to this.

In addition, when I make a change or add a checkpoint to the source that I
can edit and run in debug mode, even when it create the duplciate copy
(that I cannot edit) it seems to be picking up my changes.

If you or anyone else has any suggestions I would greatly appreciate it.

Thanks,
Ben

I hope this helps but this issue began after I received a "Source not
found" message during debugging. I was acutally debugging a program that
I had debugged many times before when I received this message. I found
that when I browsed and selected the workspace that I am working with that
I was able to debug but it was at this point that I couldn't make changes
to the code or add break points because the debugging was in a copy of my
acutally code. Also, when I selected the browse to find my workspace, it
initially listed a different workspace the my current workspace I was
using. As I said, I switched to my current workspace and could debug (or
see the code) I just couldn't make changes, or add break points and it
created a second copy of my code.

Thanks,
Ben

Check the Launch Configuration that you are using to launch your debug -
its classpath or source path must be icnluding the .class files or JAR
file from your source instead of the source itself.

Hope this helps,

I'm not sure where to make this change or what change to make. I went
into Windows->Preferences->Run/Debug->Launching->Launch Configuration but
am not sure which options I would need to change. I do not see a path or
checkbox that indicates where it is pulling the source/classes from. I
also do not see anything under the project properties that would apply.

The application that I'm running is a simple web application that I have
run/tested many times before this occured. I typically right click on the
JSP and choose to run/debug on server and it works. I'm not sure where
the options is to switch the configuration. If someonoe could provide a
more detail I would greatly appreciate it.

Thanks,
Ben

Launch Configurations are the mechanism that Eclipse uses to launch your
application(s). One is created when you run a class (or JSP in your
case), but you can also create/edit them directly.
If this were a stand-alone application I could tell you how to edit the
Launch Config, but this is WTP related (running on a server) so I
suggest you ask on the WTP newsgroup how to check/edit the classpath and
source lookup path for a server launch.

Hope this helps,
Eric

I never figured out what the cause of the issue was but to fix the debug
problem (the creation of the second window) I created a new work space,
reset all my preferences, and copied the projects from the other workspace
into it. Once I did this I was able to modify my code, add and remove
break points while debugging. If anyone ever figures out the issue please
post it here.

Thansk,
Ben

PS: I tried to post this under web tools per the previous response but
could not find the link to that newsgroup anymore.
