Glassfish 3.1 remote debugging with Eclipse

votes

I have deployed my WAR on a remote Glassfish server(not the same machine Eclipse runs) and wanted to do remote debugging using Eclipse.

Here are the steps I followed :

1) Enabled debugging in Glassfish ( start-domain --user admin --debug shopserver-grp01 ) Enabled Debug in JVM settings in the server instance.

2) In Eclipse started Debug "Remote Java Application" and successfully connected to the jdb port of the Glassfish server.

3) Changed the perspective to "Debug" and I could see the connection is successful and running server threads.

4) Toggled some breakpoints in my Service classes.

5) Open the browser and accessed my REST service with some parameters.

But the Eclipse wont pause at the marked Break points?

Any tips ? Any special compiler parameters when building ? I use Maven.

Are Eclipse and Glassfish on the same machine? - hage
No , Glassfish is a remote server - Ashika Umanga Umagiliya
Are you sure you are execting the code at the breakpoint? Put a breakpoint in String.hashCode to make sure you can really hit a breakpoint. - sbridges
thanks for the tip.it stopped at .hashCode() but not in my Service,DAO class methods ? Is it because the server/domain instance running on different JVM instance? - Ashika Umanga Umagiliya

Could you try another Java IDE or debugger to eliminate the possibility of the Eclipse debugger being bugged?

You can not debug Java classes which were compiled without debug informations. If the class does not contain this information, you are not able to debug the class at runtime. this is a special compiler option for reducing the class size and for preventing debugging.

Can you please check, whether the glassfish contains this information.

Determine whether .class file was compiled with debug info?
