call("class.method", arg1, arg2, ...) in a macro?

[Bill Mohler]

Can

    call("class.method", arg1, arg2, ...)

call a method in a class that is in a jar file in the plugins
directory?  Or does the class file need to be at the root of the plugins
directory and unjarred to be reached by such a call command in a macro?

Thanks,
Bill

ImageJ uses its plugin class loader to load the class, so it can be in
any .jar file in the plugins/ directory, as well as anywhere in the
classpath.

Note, however, that it will use the first implementation it finds.  So if
you have an obsolete .jar file early in the classpath with the class you
want to call, that one will be used.

Hth,
