问题
in Eclipse Indigo with Glassfish 3.1.2 on Linux/Ubuntu. JDK 1.6.0_32.
Update same results on Glassfish 3.1.2.2 and Eclipse Juno w/latest Eclipse Glassfish plugin.
Eclipse debugger stops on breakpoints, but does not synchronize the 'debug' tab to the current thread/location, and does not show the cursor at the current line. If I manually expand the tabs for each thread, I can figure out which thread is stopped and what line. If I click on that I can then show the pointer on the current line. Once I step over/into (F5/F6), though, the current-line cursor disappears again and I have to do it all over.
Debugger does work fine with JUnit and Java SE apps. Also the very first time I launch Eclipse and Glassfish, everything works. If I restart Glassfish though, the debugger flakes out until I restart Eclipse again.
Any one seen this and had found a fix?

I struggle with this error described by wrschneider99 for 2 days. I thought that I do not find solution. I noticed that when i "open launch configuration" for my glassfish server then error message "No server selected" is shown. I found defects for this Defect1, and Defect2. Following suggestions I installed glassfish server plugin by putting in eclipse install new software link

After that problem with "No server selected" disappear and debugging problem was fixed too! I used linux x64 and eclipse indigo. It look that in eclipse marketplace glassfish plugin is not up to date.

I know this post is old. But, upgrading to Eclipse Kepler and Glassfish 4 seems to have solved the problem for me.
