Re: Path problem?

Put either the sources together in one path or give a package
declaration to your first plugin (the equivalent to a namespace in C++).
For non-trivial plugins this is anyway the better idea.

You can then import that plugin by

import mynamespace.FirstPlugin;

similar to

using mynamespace::FirstPlugin;

to announce mynamespace.FirstPlugin to ImageJ, you need a hack called
plugins.config in the jar file that contains it or in the plugins folder
alternatively to define what to call under which menu point.
