[Pljava-dev] Can't figure out: "ERROR: Unable to find static method test.AccessFunctions.echoTest with signature (Ljava/lang/String; )Ljava/lang/String; "

Thank you! It was a runtime dependency on a jar I had to add.
I guess the root ClassNotFound is swallowed somewhere when the error comes
out.
Kind of a pain to find the runtime depndencies separately.
I had to make a command line version.

Thanks again for the help!!!
