Java environment setting after Ubuntu is reinstalled

Java here, the method to check whether you have a java path is to run whichjava in the terminal, I got/usr/bin/java. If sunjava is installed in Ubuntu, run the following command: exportmat_java =/usr/lib/jvm/jdk1.6.0 _ 10/jre/. If no, use the exportmat_java =/home/matlab 2008b/sys/

If sun java is installed in Ubuntu, run the following command:
Export maid =/usr/lib/jvm/jdk1.6.0 _ 10/jre/
If not, use the built-in matlab
Export maid =/home/maid/sys/java/jre/glnx86/jre
Reference
Ust to follow up on this, in case anyone out there is interested, I am now using Compiz version 0.6.3 ~ Git20080115.0ea58487-1 on Debian Lenny with kernel 2.6.24-1-amd64, and I am running Matlab 2008a. I have found that the latest snapshot of the JRE is working relatively well with Matlab, which you can find at http://download.java.net/jdk6/binaries. I instruct Matlab to use this JRE by adding this line

Export maid =/usr/lib/jvm/jdk1.6.0 _ 10/jre/

To the Matlab startup script which for me is located at/usr/local/matlab 76/bin/Matlab (your Matlab root may differ, and the location of your JRE may differ ). one key requirement is that you create the symbolic link from motif21 to motif12 in the amd64 directory which for me is located in/usr/lib/jvm/jdk1.6.0 _ 10/jre/lib/amd64 (again your location may differ ). I have found that the old workaround "export AWT_TOOLKIT = MToolkit" cannot be set for any of this to work. also know that the motif12 link is
Total kluge that I don't understand, so proceed at your own risk. Good luck!
