Ubuntu重装后Java环境的设置[Linux安全]

　　java下载地址在这里,检测你能否有 java 途径的办法是在终端中运行 which java,我得到了/usr/bin/java

　　假如Ubuntu下安装了sun java用下面的号令

　　export MATLAB_JAVA=/usr/lib/jvm/jdk1.6.0_10/jre/

　　如没没有,利用matlab自带的

　　export MATLAB_JAVA=/home/matlab2008b/sys/java/jre/glnx86/jre

　　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 MATLAB_JAVA=/usr/lib/jvm/jdk1.6.0_10/jre/

　　to the Matlab startup script which for me is located at /usr/local/matlab76/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 a
