Default How to include 2 version of jar in project

Hi,
I'm developing small app in jsp using eclipse.

Can You please tell me how I can include 2 version of jar in one project (this are old and new version of same jar)

I need in one project connect to old and new system and I need both jars - but they have same methods etc so I created 2 projects where first is dynamic web projects with jars in WEB/lib and second project is normal java project where I added jars to project.

I added second proj to first and I can use class from second one in first (there is no error in eclipse) but when I try to run app I have error on place where I'm creating object from second class.

Thanks in advance

Two versions of the same JAR cannot be used as the class versions shall be different. Add the latest version.
