Execute script Operator include many .java files

Hello,

I have a project in java that is consisted of 4 .java files 1 main.java and 3 others within a package called cs.nlp.module.

In the execute operator I have included the code of main.java but I cannot figure out how to include the other files.

import cs.nlp.module.File1; etc. does not seem to work.

I even try to put the files right in the lib folder of RM but no success.

Any help is highly appreciated

With regards
MM

you need to compile the java files to a jar first. this can be used then.

thank you, I have compiled everything to a jar. Placed the jar in lib folder of rapidminer.

I have created a draft process to test it but I get a java.lang.ArrayIndexOutOfBoundsException of a function within this jar.

here is the process

you can find a Netbeans project I made to test if my jar works that works pretty fine.

Any help would be highly appreciated!
