I'm working on a set of website source code and I am using Eclipse jee for debugging.

In my attempts to debug some of the java source code, I am getting a pop-up window with a tab name of:

org.apache.catalina.core.ApplicationFilterChain

and a partial view of the page is:

Quote:

Class File Editor

Source Not Found
_____________________________________________________________________________
The jar file /usr/share/apache-tomcat-8.5.63/lib/catalina.jar has no source
attached.

You can attach the source by clicking Attach Source below:

Attach Source <--- This is a button
_____________________________________________________________________________

below this line is a large amount of information which I am guessing was
extracted from catalina.jar file.

I have looked on the internet for this issue and found some references which I have looked at quickly, but so far I have not learned anything that will help me through it.

I have a few questions:

1) Is there a way to tell eclipse to ignore trying to debug selected jar and class files?

2) Isn't it self evident that if the source is not included, the source java code is not being debugged. I could understand a warning from the debugger that a jar or class file is being ignored because no source is attached, but I see no reason to stop the debugging process and post this page.

3) When this window pops up, why is there not a 2nd button that says: "Ignore this (jar/class) file?"

I would appreciate comments to my questions and I'm hoping there is an easy way to configure Eclipse to work around this problem.

Hi

Im my experience this only occurs when you stop in a class file that has no source. It is not a popup that stops the debugging, just a 'code view' that explains its deficiencies and how to remedy it. In some cases such as newInstance() you can just step through to some better code. In other cases step return , or run to a better breakpoint. Better still find the sources so that you can actually see what is happening. As an Open Source project I'm sure that there is a Tomcat source distribution.

You should be able to use Step Filtering.
