ok i'm gonna make it easier on you.
i gess i found what is the problem but have no idea how to solve it.
when i obtained the .jar file i also obtained a README.txt file in which it is written the following phrase:
** If a library on the projects classpath also has a Class-Path element*
specified in the manifest,the content of the Class-Path element has to be on the projects runtime path.
I'M SORRY BUT I DID NOT UNDERSTAND WHAT IS MEANT BY: what is "the projects runtime path"?
the content of my manifest is:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 10.0-b23 (Sun Microsystems Inc.)
Main-Class: hequalifies.ui.HeQualifies
Class-Path: lib/PlugIn
X-COMMENT: Main-Class will be added automatically by build
I'm having problem with lib/plugin.
