Even so the jar files exists and are in the correct folder, I get the NoClassDefFoundError. Why? What I am doing wrong?

The Classpath definition is .\thirdparty\lib\;C:\jsystem\runner\lib\ant-jsystem.jar;C:jsystem\runner\lib\cli.jar;C:\jsystem\runner\lib\commons-logging-1.1.jar;C:\jsystem\runner\lib\embeddedCatalina.jar;C:\jsystem\runner\lib\fileParser.jar;C:\jsystem\runner\lib\filetransfer.jar;C:\jsystem\runner\lib\j2autoit.jar;C:\jsystem\runner\lib\jsystem-launcher.jar;C:\jsystem\runner\lib\jsystemAgent.jar;C:\jsystem\runner\lib\jsystemApp.jar;C:\jsystem\runner\lib\jsystemCommon.jar;C:\jsystem\runner\lib\jsystemCore.jar;C:\jsystem\runner\lib\snmp.jar;C:\jsystem\runner\lib\stations.jar;C:\jsystem\runner\lib\swing.jar;C:\jsystem\runner\lib\tcl.jar;C:\jsystem\runner\lib\vbshell.jar;C:\jsystem\runner\lib\web.jar;C:\jsystem\runner\lib\wget.jar;
