"Loading Java Native/Shared libraries"

For the RapidProM extension of RapidMiner, we need to load some external libraries, e.g., LpSolve for integer linear programming.

 

We used to do this using System.load(...) / System.loadLibrary(...) calls.

However, the new security rules within RapidMiner do no longer allow this and an AccessControlException is generated for this type of code.

Is there any way (like some static utility class) whith RapidMiner that allows for this type of loading?

Without this type of loading, a lot of operators are no longer able to function.

 

kind regards,

 

Bas.

    Can you please email me at my username at rapidminer.com? We will figure out an interim solution for your extensions and make sure that users can use them with RapidMiner 7.2.
