Error "org.omg.CORBA.portable.UnknownException: vmcid: 0x0 minor code: 0 completed: Maybe]"

I was bugged by this error yesterday. I didn't have any clue. I tried to do clean build on WID (WebSphere Integeration Developer). Its doesn't help. Restarted the server couple of times, removed from the server and published again no way & no improvements not even a single step forward.

I got tensed thinking of the whole day, will go in vain in debugging this issue. Search didn't give us much information. Then got some clue from devworks forum. Oops there were lot of unanswered questions, few of them got some suggestions same as clean+build and deploy.

I tried a different combination, removed the project from server. (checked in the admin console). Delete all the projects which are generated by WID (App,EJB and WEB Projects). Then do a clean build and deploy application. Mostly this works b'coz it worked for me.

Note : Even after the below steps your facing the problem check in devworks or open a PMR with IBM.
