[Eclipse] Debug doesn't work properly.

Thread view:

I am new to eclipse. I made a java project that use tomcat. When I
want to use the debug's perspective my cursor don't follow the ligne I
supose to be debugging. I can debug but I have to check where the
thread is, go in the good class and go to the good line.

I try to create the same project again and I have the same problem.

However, I created an other project and the debug work properly. Maybe
it something with my tomcat?

Does anyone had this problem before?

Thanx :-)

Sounds like the line number information of the code is missing. If code
has been compiled without line number information, the debugger cannot
track your steps inside a method.

In particular code like Tomcat, and even Java's own runtime libraries
have been compiled without the linenumber info (I think for reasons of
jar size, but maybe also speed, though I doubt the last).

In your own code, you can ensure that Eclipse add this line number info
to your compiled code by selecting "Add line number attributes" in
Window -> Preferences -> Java -> Compiler -> Compliance and Class files.

The debugger can track my steps inside a method. If I check in the
threads list, I can see the line where I am suppose to be. If I use
step over or step into I can see the line change.

I checked and this option is already check :-(. I have no clues why my
cursor does not follow the debugger's information!

Thanx :-)
