Hi, the application server I use (orion) uses pure java. So I just added the necessary parameters for remote debuging to the java command: java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5000 ... ... and opened a remote debug session. This worked fine for me. I hope this helps you.
edit the startWeblogic.cmd of your server find the word "set STARTMODE=" and edit it to "set STARTMODE=false" then it start with develop mode(no debug mode)
