Java Class Library with dmServer question

[TeamMc]

I have a java class library jar that was developed by a 3rd party.

I want to use it in a dmServer Bundle Project.
I add it as a reference library which gets by the compiler as expected.

However, after I deploy to dmServer and use the bundle... I get an exception that indicates that the class is not loaded.

Does dmServer NOT allow a jar file to be loaded this way?

Ok...took the Class Library and used the plug-in project in STS to convert the class library to a plug-in that is targeted for the OSGI framework.

Exported to a jar file and deployed to dmServer 2.0.

How can I use this package in Eclipse when developing an OSGI Service?
In the OSGI Service I am in the manifest and cannot add this package that is on dmServer.

TIA
