How does JCC choose which java version to use?
Hi!
How does JCC choose which java version to use?
I've had some users that had troubles (on linux) because they had both java 6 and java 7 installed,
and it seems that JCC was invoking java 6 while the .class files that JCC was used on were created with java 7.
Is there some way to influence which java version that JCC picks up?
Best regards,
Toivo

Yes, that's correct, use JCC_JDK.
If you don't, the logic to figure out which to pick depends on the OS.

Hi,
I guess Andi is the best to answer, but just to make sure that you have set
the JCC_JDK variable set. JCC tries to find it by itself but if it's set it
uses JCC_JDK as the path to the java.
Regards
