Description Eric Rich 2013-08-23 17:29:18 UTC

Description of problem:

Can Java based cartridges be configure to use other JDK versions, that might be installed on a node with alternatives? 

[Idea]: allow marker files to select any one of the nodes listed alternative versions of Java.

I've converted proposal into a trello card as it is a non-trivial change.

This is a great use case for a downloadable cart.  There is too much of a test issue with including all possible versions in the standard carts.

Comment 3 John Keck 2014-04-14 19:45:04 UTC

It should be noted that using /etc/alternatives/ you can change the behavior for all gears running on a particular node.  If you install a 3rd party JDK and point /etc/alternatives to that then all gears will run that 3rd party JVM.

Also, on a per application instance basis - you can override the JAVA_HOME to point to whatever binary you would like; however, this is a manual step and is not built into the RHC or Web Console.
