Tutorial:Debugging an Application Running on BUG Y.T
From BUGwiki
Contents |
Overview
This page describes how to enable the remote debugging of Java programs with BUG 2.0 software.
BUG Setup
Shutdown non-debug JVM
From an SSH console logged into the BUG, type:
/etc/init.d/felix stop
Now start the debug-enabled JVM with:
/etc/init.d/felix-debug start
You should see a message saying that the JVM is waiting for a connection.
Host Setup
Your host should have Eclipse Helios installed with the Dragonfly SDK. To remote debug an an application, have the application source code in the Eclipse workspace and set a breakpoint in Activator.start().
In Eclipse, from the Run menu, select "Debug Configurations...". A launch dialog will appear. Create a new entry under "Remote Java Applications". Set the host to be the IP address of the BUG and the port to 5000. Click the debug button.
After a few moments the breakpoint in your application should be tripped, and now you can step through your code remotely!
Troubleshooting
If the breakpoint is never reached, confirm in the logs on BUG that the application was started. If you don't get past the "waiting for connection" message, check your network settings. Contact us at #buglabs@irc.freenode.net or our forums at http://bugcommunity.com.
