"RM doesnt start on Debian"

Legacy User

If I run  java -jar lib/rapidminer.jar or scripts/RapidMinerGUI RM crashes.


This is the CLI output:

I adjusted the JAVA_HOME in scripts/RpidMinerGUI to:

RAPIDMINER_HOME=${HOME}/rapidminer-4.4
JAVA_HOME=/usr/lib/jvm/java-6-sun/jre

xstream.jar is there:
drzel@amd64:~/rapidminer-4.4$ locate xstream.jar
/home/drzel/rapidminer-4.4/lib/xstream.jar
/usr/share/java/xstream.jar

xpp.jar is not there, but:
drzel@amd64:~/rapidminer-4.4$ locate xpp2.jar
/usr/share/java/xpp2.jar

Maybe there is a package missing?

This happened on both 32-bit debian lenny 5.0 and 64-bit lenny.

Or is this really an unsupported like the message suggested?
