Java Development Tools

I am using bea-weblogic plugin to run app server from eclipse. I am unable to stop server from eclipse .I click stop button , eclipse says it is stopped , then I start , i get port is already occupied , so every time i click the stop button , i go to my process kill java.exe and then restart server, moreover I click stop from eclipse eclipse says stopped , and in browser I point to localhost/console , I still can see my admin console , this tells server is still on . Any help is greatly appreciated.
