Hello,

I'm a new Eclipse user and I'm having trouble with the "Step Filtering" feature. It works fine while stepping through the code, but what I'm trying to figure out is how to prevent Eclipse from trying to find source code for the java library when an exception is thrown.

For instance, when I'm using Scanner.nextInt and I enter a letter instead of a number, I get an InputTypeMismatch exception. Rather than simply showing me my code after breaking for the exception, it opens up a new code window titled "Scanner.throwFor() line: not available [local variables unavailable]". The window is blank except for "Source not found." and a button that says "Edit Source Lookup Path". Of crouse, all I have to do is click the last place in the call stack that was in my code and I can see where the exception occured, but I'd like to prevent any new tabs/windows from opening up and have it point only in my code. This is similar to the "Just My Code" feature of Visual Studio.

I've done a lot of searching, reading through the help and looking through the debugger options but I've been unable to find the answer. Any ideas?

Thanks in advance,
Nate

Hi Nate, and welcome to our brand new forums. Thanks for stopping by and asking this interesting question. If I understand it correctly, you're looking for a way to prevent source code searches outside of the classes actually in your own project?

I have seen debuggers throw up all kinds of stuff for library-level classes, so I can totally understand why you might want this. I'll be interested to learn the answer myself.

Rick,

Your understanding is correct. :-) Thanks for your reply; I'm hoping there's some hidden option in Eclipse that I haven't seen yet! I'd be really surprised if no one else has encountered this before...

Oh, I forgot to mention that I'm using Eclipse 3.3.1.1 and JRE 1.6.

Hi Nate

As far as I know, when an exception is thrown that will open up in a window when debugging.
I could be wrong, but you should be able to click back onto the main thread and see where it's going in your code.
Does this make sense to you?

Make sure the open popup on exception box is unchecked

Well done, Fred! Thanks!

Thanks very much, but that was already unchecked. When it's checked it opens up a different popup. What I'm talking about is not really a popup, it's a new source code tab in the source code window. So, thanks for the idea, but that's not the answer.

I'd like it to jump back in the call stack and show the last spot in my code before the exception was thrown.

I've attached some screenshots that I think will be helpful. Please take a look.

UPDATE: Pay close attention to the filename (and therefore the URL) of the screenshots because they explain the purpose of the screenshot. Note the popup in one screenshot (which is not my problem) and in another screenshot there is a blank white tab that says "source code not found" (which is my problem).

Yes, what you say makes perfect sense. This is in fact what I do as a workaround. However, the step filtering settings should cause it to recognize that I do not want to step inside the code of the scanner (or any library) class, right? Why does it nonetheless try to show library code when an exception is hit?

Unfortunately, after watching tutorial number 4, these videos don't seem to touch on my specific question. Thanks very much for posting the link though; it's great for people new to Eclipse like I am! I will review the other videos in detail to see if by chance they mention something about it.
