Hi Florian, It appears that RapidMiner has a Java API<http://rapid-i.com/api/rapidminer-5.1/index.html>. If your intention is to ultimately use Jess to reason over a rulebases of sheet-metal forming rules, then those rules will have to be in Jess code. In theory, you could use RapidMiner's Java API and Java proper to generate Jess rules directly -- just pipe the output from RapidMiner into a Java class that generates Jess rule code. Alternately, if you must keep the intermediate Excel files, you could write a Java class that generates Jess rules from your Excel spreadsheets. Then, if you were to update your Excel source, your Jess rulebase (e.g. Jess *.CLP files somewhere) could be automatically updated, too. For this, you may find the Apache Poi <http://poi.apache.org/>API useful to read/write Excel files from Java.
Hope that helps!
