I use Jdeveloper Studio 11.1.1.4.0, I use the ADF components on it, but for the last couple of days when I start the Jdeveloper, this Error comes up
Uncaught exception

I can't find the Database Navigator either and also this error also comes up when I use anything related to the database, I tried to uninstall the Jdeveloper and removed the middleware folder and reinstall everything to get the default but still same story.
I really need a fix for this ASAP because I'm already behind schedule on my graduation project.
Thanks.
