1) That extension looks mighty old. Please use the 5.3.x version of it.
2) If it still does nto work, please post the full log when you execute your application.

Log: Thanks.
to get the extension to load from a development environment, it either has to be a managed extension (USER_HOME/.RapidMiner/managed) defined in the managed.xml, or it has to be in the WORKSPACE/RAPIDMINER_PROJECTNAME/lib/plugins folder.

look:

then it fails to use the correct home folder. See the following log part: RapidMiner Home is the root folder of the RapidMiner Studio installation. In that folder it will try to locate /lib/plugins to load extensions. You can set rapidminer.home via system property before calling RapidMiner.init() to the correct folder, e.g. Regards,
