Sorry, my bad explanation.
I added the project B using BuildPath->Tag Project->Add, but it does not work.
I also tried adding the jar file...nothing changed, same error.
Added what where? I think you are getting confused about who is depending on who.
Start by asking yourself this questions:
Where am I?
Do I have a pulse?
Where can I find what I need?
Have I added a dependency to that?
If I have, what is the accessor of that resource?
If Project A needs resources in Common, Project B needs to add Common to the build path. Not the other way around.
