[OpenIndiana-discuss] Installing Java 7

[Roel_D]

You can have all jdk versions within /usr if you just download the tar-files without installer. 

After unpacking move it to /usr/java/jdk or wherever you like. 

After that alter/set the following in the .profile of every user:
PATH
JAVA_HOME
JDK_HOME

And point them to the java version they need. 

Solaris 10's updateprogram and some orhers relied on java 1.5 and i spend days on searching why it stopped working after i updated to java 1.6...

Kind regards, 

The out-side
