Hello,

How do you integrate? Do you create the processes from code, or parse from XML, or use the RM UI to create processes?
Although it seems it orifinates from RapidMiner.init. Do you have all jars on the classpath (with the proper classloader)?
Cheers, gabor

The process is created using XML

This error occurs in RapidMiner.Init();

ya i have added all the JARs in the classpath

Hi,

you are running your application with assertions enabled. We have not used them internally for a while, so there are quite a few broken ones I'm afraid. You will have to disable assertions for RapidMiner to run.
As a sidenote, please be aware that RapidMiner is licensed under the AGPL 3. This means that your application must be licensed under the AGPL 3 as well. If that is not possible/desirable, you need to purchase an OEM license. You can contact us here for details.

Regards,
Marco
