How to debug .class files in ECLIPSE?
I am using Eclipse 3.5 and I attached the src.zip to my global settings in Eclipse. Windows--> Preferences -->Java -->Installed JREs -->rt.jar - Source attachment - ...../jdk/src.zip
I am successfully able to step in the java core library .class files and view the source code. I building a Class which uses the LinkedList and I have set a breakpoint inside the LinkedList class.
When I debug the breakpoints in my source code (my projects) are working good but when I need to step into the java core lib .classes I get the following error in my Eclipse
Unable to install breakpoint in java.util.LinkedList due to missing line Number attributes. Modify complier options to generate line number attributes.
I checked my complier settings in Preferences and found all options checked true.
It would to great if someone can help me resolve this issue.
Thanks in advance.
You may have the compiler set to include debugging information in YOUR class files, but the class files in rt.jar weren't compiled that way. You need to either recompile all the source for the classes in rt.jar (not for the faint of heart), or download a debug build of the jdk.
