I have a java project in which I have “Referenced Libraries”. In the “Referenced Libraries” I have a .jar file of a library that I use (I use only one external library).
When I try to “Run -> Run” the code I have a NullPointerException. From my previous experience I know that it it (very likely) because my code does not see the library.
I just started to use Eclipse and it can be the I do not “connect” libraries in a correct way. Should I use some options or additional action to force Eclipse to see the .jar file of the library?
ADDED:
By the right click on the library I get a drop-down menu in which I see “Build Path”. My be I need to do something there?
Have you tried this?

Add the library’s to your build path :]
