I am working on a private data on a machine that cannot have access to the internet. I have installed RM but I cannot install the extensions, therefore, I have installed the extensions manually by copying the jar file into the plugins directory.
Storing and retrieving Weka models did not work.
Later, I have copied the extensions into the plugins/managed directory with the XMLfile and I was able to retrieve Weka models by the Retrieve component
It worked only when I copied the folder " C:\Program Files\Rapid-I\RapidMiner5\lib\plugins\managed" from another machine.
I have double checked.
