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 to do it ? I want my jar to be a part of my project and not lying in some random folder.
