RapidMiner hangs in Creating Frame in both Mac OS X Snow Leopard

psps1368

Hi
This one is driving me crazy!
For a Java Application, I must run windows virtual machine....

As the subject says, I'm stuck with RapidMiner in "Creating Frame" in the splash screen. In both Snow Leopard & Lion.
I have deleted .RapidMiner5 folder millions of times but didn't work.
Even I Installed JDK 1.7 Developer Preview (Changed the order of use in Java Prefernces) but didn't work either.
Here's the log when I run it through the terminal:

$ java -jar rapidminer.jar

Here is my java version:

$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511c)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)

I also ran it with -Drapidminer.home option, But nothing happens...

Please help me get through with this....

Finally, I solved it!!

The problem was that the path that RapidMiner was on, had space character (' ') in it!

When I placed RM in a path that had no space character, it finally passed "Creating Frame".

The app is now up & running...

RM Developers should take a look into this for the next version. (This only happens in RM 5.0 & RM 5.1, not RM 4.6)
