How to remote debug my application with an IDE?

How to remote debug an enterprise application running on web logic server in eclipse IDE(same machine)

• I am new to weblogic application server and remote debugging & have gone through several post to set up remote debugging. Some post suggest to edit setDomainEnv.cmd file while others suggest to edit startWeblogic.cmd file in my WEBLOGIC_HOME\user_projects\domains\my_domain\bin. But neither of the solutions worked for me. Listed below are solutions which I tried : 1) Edit setDomainEnv.cmd file set JAVA_DEBUG=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=%DEBUG_PORT%,server=y,suspend=n -Djava.compiler=NONE set JAVA_OPTIONS=%JAVA_OPTIONS% %enableHotswapFlag% -ea -da:com.bea... -da:javelin... -da:weblogic... -ea:com.bea.wli... -ea:com.bea.broker... -ea:com.bea.sbconsole... The port number is set to 8543 in the file if "%DEBUG_PORT%"=="" ( set DEBUG_PORT=8453 ) 2)Edit startWeblogic.cmd file I added the following line at the top of the file -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8543,server=y,suspend=n Then in eclipse,when i run debug configuration(port number : 8543), I get Failed to connect to remote VM. Connection refused. Connection refused: connect Please let me know 1) How remote debugging works? 2) How to set up remote debugging in eclipse with weblogic server ? 3) What is the difference between above 2 methods ? 4) Where do I need to add the debug command(-Xdebug....) in the startWeblogic.cmd file(at the top)? 5) What is the purpose of setDomainEnv.cmd file in weblogic server ? Thanks in advance

• Answer:

  I think it should be sufficient to just set environment variable before starting Weblogic. Start cmd and before starting weblogic set debugFlag=true. This should make weblogic open debug port which should be set to some default like 8453. You can also set DEBUG_PORT=8888 or any other free port, if you want to change it. Start Weblogic and verify that the port has been opened. You can use tools like http://www.nirsoft.net/utils/cports.html or https://technet.microsoft.com/pl-pl/sysinternals/bb896653.aspx for that (or event http://helpdeskgeek.com/windows-7/use-netstat-to-see-listening-ports-and-pid-in-windows/). In case debug port isn't open, check if you run Weblogic in development mode, because debugFlag can be ignored in production mode. In Eclipse create a remote debug configuration (and remember that this option is not available in Run configuration that is next to it on the toolbar): In point 3 on the screenshot select the project you deploy to weblogic that you want to debug. It that does not work post the problems you have.
