  • 0

I am trying to run my Java application in debug mode in Eclipse, but it’s not working. It was fine until yesterday when I could properly debug my application. I am able to run my application on the server ( Oracle OC4J Standalone Server 10.1.3) properly. Only while debugging, it continues for a long time and then shows a server time out error. I tried increasing the Server time out, but was of no use.

I also tried removing the Server and creating it again and restarting Eclipse. Is there something I could do about this?

Edit: Strack trace on trying to Run it as Remote Java Application

    There is an issue with OC4J’s debug mode enabling. Sometimes I’ve noticed that after enabling it (via opmn.xml) it will work for a while then stop working. What I’ve found to actually work all the time is editing the /bin/oc4j.cmd file and adding the line:

    set JVMARGS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=9009,suspend=y,server=y

    then start a Remote debugging session from Eclipse on the port 9009
