As question stands, it isn't. Closing as off-topic.

I had the same problem. Here is what worked for me : http://forums.pentaho.com/showthread.php?90698-exception-on-loading-Package-Manager You have to create file ..\wekafiles\props\PackageRepository.props and place the following line in it : weka.core.wekaPackageRepositoryURL=http://www.cs.waikato.ac.nz/ml/weka/packageMetaData

BTW there is WekaManual.pdf file in the installation folder of Weka. It`s written there how to manually install packages.
