Hi Everybody

I have a mac mini with OS X 10.4, all updates installed

Since Apple did not release java 1.6 for this version of the OS, I've installed soy latte (http://landonf.bikemonkey.org/static/soylatte/), an Open Source implementaion of the JDK for 1.6

If I execute java -version command I get

./soylatte16-i386-1.0.2/bin/java -version
java version "1.6.0_03-p3"
Java(TM) SE Runtime Environment (build 1.6.0_03-p3-landonf_03_feb_2008_02_12-b00)
Java HotSpot(TM) Server VM (build 1.6.0_03-p3-landonf_03_feb_2008_02_12-b00, mixed mode)



This jvm works great, swing works, everything java works, but when I start rapid miner I get

I do have X11 installed, so why do I get this error?
Is it related to plaf? How do I disable the Aqua plaf? Is it possible to disable the skins of the UI and use plain old java swing?

Any help would be appreciated

    Hi danielcohenmartoy.

    I'm affraid their is no easy option to switch off the RM Look&Feel (it is not Aqua though).

    If you do not have a chance to upgrade to 10.5 you might check your X11 setttings.

    Does other X11 applications start the X11-server automaticly or do you need to start the server before you start the X11 application?

    Ciao Sebastian.

    Hi Sebastian

    Thanks for the post

    The other applications start X11 automatically, but they are all OS X binaries.

    You ask me about x11 settings... Wich setting should I check? Do you want me to post a x11 config file here? Which one?

    Hi danielcohenmartoy,

    try this:

    - download an arbitrary Java application (the .jar file) with a gui, eg. this one here http://sourceforge.net/projects/sdedit/files/

    - try to start it with your soylatte java version

    does it work?

    If this works then I do not know what to suggest else. If it does not work then I guess something is not right with your X11-server and/or soylatte installation. I was dealing with soylatte too (but not with RM) before Apple released the java version 6 for 32Bit Macs and I rember it was a pain in the ass.

    Ciao Sebastian

    Rapid Miner 5 is confirmed to work on Os X 10.4

    Here's how


    Install SoyLatte (http://landonf.bikemonkey.org/static/soylatte/)

    Make sure you have X11 installed, it comes on the OSX install CD

    Go to "Applications / Utilities / X11", double click

    Open XTERM

    write this "/Applications/soylatte/bin/java -jar /Applications/rapidminer/lib/rapidminer.jar" (assuming soylatte is installed on "/Applications/soylatte/" and rapidminer in "/Applications/rapidminer/lib")

    The reason you have to write such a long command is that XTerm does not inherit the PATH of the OSX terminal, I don't know why.
