Enable remote debugging in Jboss

Jboss configuration file

For Jboss 4,5,6 AS and 6.x EAP standalone mode, append to your JAVA_OPTS the following option:

-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n

For Jboss 7.x AS/EAP 6.x in domain mode, in host.xml add the corresponding jvm option in the server group you need to debug:

        <server name="server-one" group="main-server-group">  
            <!-- Remote JPDA debugging for a specific server  
            <jvm name="default">  
              <jvm-options>  
                <option value="-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"/>  
              </jvm-options>  
            </jvm> 

-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n
