Difference on Changing Java SDK version between Solaris and Linux

Change Java SDK version

1. go to bin folder
/bin/ -> ls -l
2. change the symbolic link to point to the new versionln -s /usr/jdk/jdk1.6.0_20/bin/ControlPanel ControlPanel

For Linux used only:
Change Java SDK version

1. backup old java file
2. change the symbolic link to point to new version

e.g. 

mv java java.bk
ln -s /usr/local/jdk1.6.0_20/bin/java java
mv javac javac.bk
ln -s /usr/local/jdk1.6.0_20/bin/javac javac
mv javadoc javadoc.bk
ln -s /usr/local/jdk1.6.0_20/bin/javadoc javadoc
mv javah javah.bk
ln -s /usr/local/jdk1.6.0_20/bin/javah javah
