Websphere works when run but fails when debug

Question

I'm using Intellij with WebSphere 8. When I run from within IDE the server works normally. When I try to run it in debug mode however, it fails with the following error:

C:\IBM\WebSphere\AppServer\profiles\AppSrv01\bin\generated_websphere_server_start_script.cmd
C:\IBM\WebSphere\AppServer\java\bin\java -Dfile.encoding=windows-1252 -classpath "C:\IBM\WebSphere\AppServer\runtimes\com.ibm.ws.admin.client_8.5.0.jar;C:\IBM\WebSphere\AppServer\plugins\com.ibm.ws.security.crypto.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.1.3\plugins\webSphereIntegration\lib\webSphereIntegration.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.1.3\plugins\JavaEE\lib\javaee-impl.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.1.3\lib\openapi.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA 13.1.3\plugins\webSphereIntegration\lib\specifics\webSphereClientImpl.jar" com.intellij.javaee.oss.process.JavaeeProcess 62847 com.intellij.j2ee.webSphere.agent.WebSphereAgent

I tried almost everything I have no idea what the problem is. I did google it for several hours with no luck.

Do anyone know what this all is about and how can it be fixed?

Here is my server configuration:

Answer 1

Solution 1 unchecked the Pass environment variables check box and restart the server in debug mode. it should work properly.

Run --> Edit Configuration --> websphere server --> Startup/Conections tab select debug, you will see the Pass environment variables check box. it need to be unchecked for debug to work.

Solution 2 if debug mode of websphere is working in eclipse and not working in intellij that reason i found out is debugging serverice on the websphere is already started and intellij is again trying to start the debggin service. so stop the service from websphere console (Servers > Server Types > WebSphere application servers > [serverName] > Debugging Service) and all the default configurations in intellij should work.
