[SOLVED] Error launching RapidMiner from RapidAnalytics web client

mylesbaker

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?

Hi,

as stated in the other post this has already been fixed. Unfortunately the 5.3 release has been delayed but should be released at the end of november.

Best,
Nils

Is there a way to connect to the server when I launch RapidMiner from my local installation? I'm trying to install RapidAnalytics for an enterprise application and would like to show a proof-of-concept.

All solved.
