Does anyone know if there is a way to programatically load classes in an
external jar using the current project's classloader at runtime?

Thanks,

Go to the popup menu on the project and select properties.
From there goto Java Build Path, go to the Libraries page,
go to "Add External Jars..." button and select your jar.

Well he/she talked about 'at runtime'. Maybe there is
some dynamic behaviour wished.

Well there is another way (I know worked for Applets).
As far as I remember, you can load the jar as a resource.
Then you can use the classes by getting the Class instance
by name (forName i think) and get instances by
create/get/newInstance (not sure which one and to lazy
to look at;)

Hope that works for applications too.

PS: If you gonna debug some dynamic code just point
a source to it. (debugger dialog i think)
