BlackBerry® Professional Software and BlackBerry® Enterprise Server Express

Fairly straightforward question... we just upgraded to BES Express 5.0.4 for Exchange and I noticed during the install that Java 6 Update 31 was installed. I'm assuming that BES now exclusively uses J6U31 now but as everyone knows BES and Java do NOT co-exist peacefully and updating Java on a BES server is painful to say the least.

We now have 4 Java versions on our BES Server:

Java 6 Update 15

Java 6 Update 18

Java 6 Update 30

Java 6 Update 31

Best practice is to get rid of old Java versions due to security holes... can I safely remove the old versions or will that knock out my BES server?

You can remove the old version, but if you imported certificates to the java keystore, make sure to import them to the keystore of the new version as well.

Try to restart MDS CS, BAS and Collaboration service (if installed). If it does not start, the java/image path was not updated by the installer. this can be done easily in the registry.

Hmm don't ever recall importing anything so I'm guessing it's safe to go ahead.

Is there a way to check the registry ahead of time to ensure all the BES java paths are pointing to the new Java version? Is there a list of registry entires to check somewhere?

hi!
What's about actual Java Version 7 Update 13/15?? Is it even possible to use Java Version 7 with BES 5.x (5.0.4 in our case)???
thx!

How to upgrade or update the Java Runtime Environment on the BlackBerry Enterprise Server

thx!

My colleague has upgraded to Java 6 Update 39 last week and had some troubles afterwards. But solved it with the community descriptions ...

and I just upgraded our BESX to 5.0.4 + Security Fix for TIFF images and it installs Java 6 Update 31 ... so, I used the instructions here to uninstall Update 31 and use Update 39 again ...

For nobody except us admins has access to BB server and no one should surf internet on it, we maybe won't need any (further) Java update (Java 6 is EOS, and latest and recommended version is 7 Update 15) but I'll check with my boss if he can sleep better when Java is actual everywhere
