Solaris

I am using a solaris zone in Sun blade-T6320 which has a java version "1.5.0_18" i want to update it to 1.6.0.16 or higher , how can i do that , does i need to add the new java package to the global server or just instal it in the zone itself.
do i need to remove the older version or and install new version or direct installation of newer version will update the java version for my zone..
Please Sugest..

You don't need to remove older vesrion of java.
You can proceed with installation of newer java version on non-global zone, no need to install on global zone.

If you have whole root zone, If you have sparse root, don't change symbolic link "/usr/bin/java", instead change your PATH variable in /etc/profile file. Bcz changing symbolic link may affect functionality of other non-global and global zone.

Please reply back in case of further queries.
