Making a jar file from a project instead of a war. The problem with a war file is that it's not allowed to execute main functions.

To solve that problem one has to make a jar instead, but what if you're project in your favorite IDE already creates a war.

Solution:

 * make an ant script that creates a jar (see attachment)
 * execute: ant -f buildJar.xml jar
 * to start a program, execute the following command:
   * java -cp !jarfile.jar:lib javamainfunctionclass
   * for example:
     * java -cp molgenis_!distro.jar:lib handwritten.importers.Start
