Java – Can’t start WebLogic admin console

I'm wondering how to fix this error. We had the wrong Java installed on my machine when I got it, so my boss installed JRocket to fix things.

WebLogic has been having problems ever since. I cannot perform my job functions because I cannot start the admin console to deploy my program.
