Is it advisable to have more than 1 JRE on a server ?
We have Linux box which has a bunch of existing applications . We have 1.4 JRE Installed
on it and some of the scripts use it . We have a new application that needs to be
built .But this new application needs 1.6 JRE .
My question is
1.Is it advisable to have more than 1 JRE installed and have my application point to that
2.If we are to upgrade to 1.6 whats the risk of breaking the existing applications
3.I am confused on whether to follow option 1 or 2 .which is the standard one ?
