[SOLVED] Error launching RapidMiner from RapidAnalytics web client

Hi everyone,

this is my first post, so be gentle! I have been using RapidMiner for the last few weeks and I just finished installing RapidAnalytics. The server is configured with a postgres database. The client can be reached by

http://LASLA40000751:8030

and I created a dummy accessor

username: user
password: password

I accessed the client from two different computers with different Java web frameworks (6 and 7, windows and mac, respectively). The executable opens, but when opening an exception is thrown. The launch file is followed by the exception. Any ideas on what's going on here?
