Re: Determining default JDK

There's a waterfall of the tobe used JDK on i ,which is defined by code,
if there's no JAVA_HOME defined. You can check the info-center for the
waterfall list. The only way you can change it is to set JAVA_HOME
environment. IBM i JDK read this env to choose the JDK tobe used in this
job. If the defined JDK by JAVA_HOME is not installed on the system, error
would be thrown.

Best regards.

Subject: Determining default JDK
Date: Fri, Feb 26, 2016 2:20 AM

I'm trying to determine how to set the default JDK.
I've read the following:
[1]http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_72/rzaha/rzahainstalljdk.htm?lang=en

So I see that I can set a JAVA_HOME variable. I'm not sure if the
vendor
product reads that. I've asked the vendor a question and I've heard
nothing back on that.
I also read
[2]http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_72/rzaha/multjdk.htm?lang=en
and it talks about an order of precedence.

I was wondering if there's some third option. Like some directory that
things check before any of these? Like I may have the following
directories
jdk60
jdk626
jdk70
jdk71
jdk80
all in /QOpenSys/QIBM/ProdData/JavaVM
I was wondering if there's some 'default' directory that uses a symbolic
link or some such thing to point to whichever of the above you want.
