How to disable debugging underlying classes (change the source attachment) [message #310397]

Hi,

When I am debugging and stepping through a program, and try to execute the
"importPreferences(FileInputStream)" method of class
java.util.prefs.Preferences, I see a page for the class
"URLClassPath.class".
It mentions that the source attachment does not contain the source for the
file URLClassPath.class. You can change the source attachment by clicking
"Change Attached Source" below:

There is a button seen under this with the message "Change Attached
Source..."

I don't want to step into the code for URLClassPath.class, but this does
not go away. This shows up 5 to 7 times after this, each time I click the
"Step Over" or "Resume" button. I have to close the new tab and click
resume every time. In the end the code works, but this is annoying to have
to do this every time, even though I do not have any breakpoints set here,
and even after pressing the "Resume" button.

I have searched the forums, Eclipse help, and Google, but have not found a
solution to this.

Does anyone know of a way to not have the underlying classes show up while
debugging? Is there an option that we can set to do this?

If it is trying to step into URLClassPath you must have told it to step
into that code; so why not just avoid trying to step into it?
There is also the feature of Step Filters - investigate in the Eclipse
Help to learn how to configure and use it.

Hope this helps,
Eric

If you tell Eclipse to use a JDK instead of a JRE for your project then
the source for the java runtime classes are automatically set correctly.

If I'm reading you right, you want to specify some classes that you
don't want to step into? I think what you want is...

Window -> Preferences -> Java -> Debug -> Step Filtering

I hope this is what you're looking for.

Rem

Hi,

Thanks for the suggestions.
The class "header" that keeps popping up while debugging is for
classes.sun.misc.URLClassPath.

The IDE I am using is BEA Workshop for Weblogic Pro, which is based on
Eclipse 3.2.1.

I tried changing settings for "step filter": I disabled it by clicking the
toggle button, and also unselected all classes in the menu for "Window -
preferences - java- debug - step filtering". But I haven't seen a a change
in behavior so far. Any time I step over (F6) code for
"importPreferences(FileInputStream)", the header page for URLClassPath
still shows up. I think I need to study step filter in more detail.

Thanks for your help,
TD.

Is it possible that you've got a Java Exception breakpoint set, and
something in there is throwing an exception?

Hey Walter,

That was it!
I have no idea how, but there was a Java Exception breakpoint set in the
debugger for FileNotFoundException. I hadn't noticed until now, and this
was causing all the problems. Actually this had begun to happen even for
creating a JFrame! Weird. I was seriously thinking about getting a new IDE.

I removed that Java Exception breakpoint and everything works fine now.
Thanks for the info, it really helped.
TD.

TD, At least for me, just above the top of the call stack in the
debugger is a line that 1) gives the thread name and 2) the reason the
thread is showing in the debug window. For breakpoints it says
"breakpoint at line 32 etc" For Java Exceptions the exception name shows
up there. You should have seen FileNotFoundException. Something to
look for next time.

You may have clicked on the name of the exception thrown in a stack
trace. This tries to set a breakpoint when that particular exception is
thrown.
