RE: How to Set Java Version

You can lose that one, too. It is the 1.3 JDK, as I recall.

Look at the system values. There's one for setting the system default
JAVA_HOME environment variable.

The java command in qshell (which is what's called by RUNJAVA and all
the other ways of starting java) in the newer i5OS versions uses
JAVA_HOME to find the java runtime unless you do something specific to
change it. There is a document that specifies the order that various
places are searched. For instance, if you specify a java.properties file
in the java command, that will override the JAVA_HOME value. You may be
seeing this in your app server; it's startup may include a specific
designation. WAS is notorious for being very version-dependent, for
example, so they usually specify the JRE in their startup script.

So then you feel it would be safe (or reasonable anyways) to remove:
5761JV1 *COMPATIBLE IBM Developer Kit for Java
5761JV1 *COMPATIBLE Java Developer Kit 1.4
5761JV1 *COMPATIBLE Java Developer Kit 5.0
5761JV1 *COMPATIBLE J2SE 5.0 32 bit
5761JV1 *COMPATIBLE J2SE 5.0 64 bit

?

Opps I would keep 5761JV1 *COMPATIBLE IBM Developer Kit for Java.

Yep. I always wonder why more people don't just do that. I
realize there was some software that declared it needed a specific
version (usually
1.4.2 if I recall correctly,) but if you're at 1.5 or above...

Ken,

Which version of java 6 are you trying to use? I would recommend
license option 11, Java SE 6 32 bit. License option 10 for Java 6

(classic) does not exist at V7R1.

Documentation states that java.version=1.6 is ignored. The JDK
version is determined from the value of the JAVA_HOME environment

variable.

AddEnvVar EnvVar('JAVA_HOME')
Value('/QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit')
Level(*SYS) Replace(*Yes)

Another option is you can remove other instances of the java
license program and it will default to what is available.

Hope that helps.

Steve
