Q:

How do I cross check whether an Imported a jar file is successfully added or not in Eclipse?

I am supposed to replace existiong API with Apache POI 3.16. I have downloaded poi-3.16.jar and have added it in my Eclipse libs folder. How do I check if it is successfully added or not?

A:

Go on configure  buildpath and see that jar is there or not with correct path.

right click on project
configure build path go on libraries
now check you jar folder or jar file is present or not.
or you can check by use one of class of this jar like HSSFWorkbook if it is imported means this jar is added successfully otherwise you need to add.
