===Eclipse, Export using FatJar===<br />
Eclipse Export of Projects that use eternal jars:<br />
Use FatJar: http://fjep.sourceforge.net/<br />
It adds the Entry "Build Fat-JAR" to the Export-Wizard.<br />
In addition to the eclipse standard jar-exporter referenced classes and jars are included to the "Fat-Jar", so the resulting jar contains all needed classes and can be executed directly with "java -jar", no classpath has to be set, no additional jars have to be deployed.</div>Torben
