"Error when running WVToolRapidMinerExample.java"
Hi all,
When I run WVToolRapidMinerExample.java it fails and shows this error message:
Exception in thread "main" com.rapidminer.operator.OperatorCreationException: No operator description object given for 'WVTool'
at com.rapidminer.tools.OperatorService.createOperator(OperatorService.java:531)
I have installed the WVTool plugin and I set the rapidminer.home property correctly but I checked operators.xml and no description object is defined for WVTool. Any ideas what do I have to do in order to run this sample program?
Thanks in advance,
Behrang

Thanks. The Java example in the downloadable package is still using WVTool as the operator name though. It would be better to update it to use TextInput cause for users new to RapidMiner it is a source of confusion.
Hi,
thanks for pointing this out. We will update this.

the WVTool plugin was renamed to "Text Plugin" about two years ago. At the same time, we decided to split the WVTool Operator into an operator "TextInput" together with small and specialized operators for the different tasks. Please have a look into the samples delivered with the new "Text" plugin and you will get the idea what have changed here. In short: rename "WVTool" to "TextInput" and add appropriate inner operators for the desired tasks like stemming etc.
Cheers,
