How can I configure remote debugging in Eclipse with JBOSS server 4.x version?
So far,
Step1: I have modified the run.confg file. By uncommenting the below line. Sample JPDA settings for remote socket debugging:
JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"
Step2 : Then I configured Eclipse in debug configurations. It's saying:
Failed to connect to remote VM. Connection refused.
What you are asking is not specific to either Java EE or JBoss 4.x - you can debug any Java process in case you specified the remote debugging runtime parameters when starting the JVM.
In your setting the -Xdebug parameter is missing, so your line would be:
JAVA_OPTS="$JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"
Now it should be able to connect, in case you are using the correct host and your specified port 8787. In case it's still not working, it's most likely a firewall issue blocking the port.
