I manually copied the my sql connector jar to lib folder of my sql jdbc project. I had some old jars already in that folder and which were also easily added to build path before. Now, I forgot how i did it and i don't see that the lib folder when i try to add the jar to build path. How do it ? I want my jar to be a part of my project and not lying in some random folder.
Try to go Window > Preferences > Java > User Libraries and add new user library that point mysql connector.And then use this library to your project.But don't forget to delete your old mysql connector jar in your lib folder.Try this way.
