it seems that you do not use the appropriate Java version. The non-Windows package of RapidMiner (....zip) needs at least Java 5 or higher. You can download and install the latest Java version from Sun.

did you try to use Java 6? It is now (finally!) available for Mac and probably will resolve your problems.

Thanks

One should mention that Rapidminer requires Java 6 in order to function with OS 10.5 / 10.4! It is NOT compatible with Java 5 aka 1.5xxx
So:
1. Download the newest JAVA Version from Apple.com (google for JAVA OS X)
2. Install
3. Search for JAVA Properties in Spotlight
4. Change the order of the elements in the bottom like shown on the picture.

is it possible that you provide me the with Java 1.5 built rapidminer.jar? Maybe you can provide a download link?
Thank you very much in advance.

Sorry for the newbie question.
Thanks,

I'd like to echo Joe's question above -- how can one install RM 4.2 on Mac OSX 10.4.11? I have Java 1.5.0 installed, but double clicking on lib/rapidminer.jar does not launch the program. When I try to run that file from Terminal using java -jar lib/rapidminer.jar, I get the following errors: Any idea why this might be happening? Thanks very much in advance.
currently the only alternative is to download and build RapidMiner yourself from the CVS version (it's actually quite easy by using Eclipse and is described in detail on our web site). The next release (4.3) will again be delivered based on Java 5 but it will take some weeks for some final tuning before we will do this release.
Cheers,
Ingo
