[Eclipse Debugging] : Enable Remote debugging in wildfly JBOSS

Just try running standalone.sh script in debug mode :

./standalone.sh --debug 

This starts the jboss in debug mode, and the port 8787 is open for debugging. 

Start remote debugging from eclipse using 8787 as the debug port.

In case  your jboss is started as a service , locate your startup script  in /etc/init.d directory and
add --debug flag to the standalone.sh script invocation. This will help your service to always start in debug mode.
