Debugger disconnected from local process.

Question

When I debug my source code I set a breakpoint and from there use step into or step over two to three times and then debugging stops with the message "Debugger disconnected from local process." I set the breakpoint at different positions and always had the same effect. When I run the code that part I try to debug does work.
What can I do to debug that part (want to watch certain variables in that part)? I already tried to set more breakpoints and used resume to step to the next breakpoint, but again debugging stops.
Thank you very much for your help,
C.D.

Hi Carola,
The message "Debugger disconnected from local process." is written to the log window when the debuggee process terminates.
In your case, it sounds like the debuggee process is terminating unexpectedly early (perhaps because the JVM died). To figure out why that is happening, I'll need to know some more information:
What kind of program are you debugging? Is it a Java Application with a main method? Or, is it a Servlet or JSP? Or, is it an EJB? Or, an Applet?
If your program is small, would it be possible for you to send it to me so that I can reproduce the problem myself?
What J2SE version and what JVM are you using? The J2SE is specified in the Project Settings dialog on the Libraries panel. The JVM is specified in the Project Settings dialog on the Runner panel.
If the problem you are seeing turns out to be a bug in the JVM, you can probably work around it by switching to a different JVM. Again, this is specified in Project Settings dialog, on the Runner panel. If you are currently using OJVM, you could try switching to HotSpot (also called Client). However, you will notice that debugging is much faster with OJVM than with other JVMs.
Also, what platform are you running on? Windows NT? Windows 2000? Windows XP? Linux (what kind of Linux and what version)? Solaris (what version)?
