Is there anyway to upgrade the installed JRE in the system? We are having 1.5.0_08 installed in out HP Unix system.We have to upgrade this to 1.5.0_15.Is there a way to patch up the existing JRE and upgrade to a newer version.Or can this only be achieved by installing the newer JRE and set this in the system PATH.
What’s usually done is to have multiple JRE installed in separate directories (JRE_1_5_10, JRE_1_5_16, JRE_1_6_3, …) and use some symlinks as references as JRE_1_5 that will point to the latest version of JRE 1.5, same for JRE_1_6, and eventually, JRE that will point to the latest version of the JRE.
Doing so, you just need to update the symlinks when you choose to use a newer version and always refer to the symlinks for systems that are ‘upgradable’.
