ok. then it's not an issue of /qoepnsys file system. I guess I got the
cause of it. That system no matter which release it is, please ask
customer to upgrade the Java group PTF to latest level. The error message
of the java -version indicate that some required PTFs are not on the
system, which are required by Java 80. 
Best regards.

Thanks. I was hoping to figure out a way to test this without having to
shut down the customer's Tomcat server and swap CPPs for the STRTOMCAT
command (i.e., the Tomcat universal launcher program we provide with our

And here is what I got:

/QOpenSys/QIBM/ProdData/JavaVM/jdk80/64bit/bin/java -version

Environment variable QIBM_JVM_ILE_HOME must be set when JAVA_HOME is not
a JV1 option directory.

The capitalization difference made no difference:
/qopensys/QIBM/ProdData/JavaVM/jdk80/64bit/bin/java -version

Environment variable QIBM_JVM_ILE_HOME must be set when JAVA_HOME is not
a JV1 option directory.

Same story for Java 8 32-bit:
/QOpenSys/QIBM/ProdData/JavaVM/jdk80/32bit/bin/java -version

Environment variable QIBM_JVM_ILE_HOME must be set when JAVA_HOME is not
a JV1 option directory.

But Java 6 32-bit gives:
/QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit/bin/java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr14-20130705_01(SR14))
. . .

and Java 6 64-bit gives:
/QOpenSys/QIBM/ProdData/JavaVM/jdk60/64bit/bin/java -version

java version "1.6.0"

Java(TM) SE Runtime Environment (build pap6460sr14-20130705_01(SR14))

IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 OS/400 ppc64-64
jvmap6460sr14-20130705_01 (JIT enabled, AOT enabled)
. . .

Something is clearly wonky with the Java 8.

Actually, since it's not *our* box, *we* can't. But the *customer*
presumably can, and I was already thinking of that myself, if we can't
dope this out.

Incidentally, a Google search on "QIBM_JVM_ILE_HOME" (with or without
the complete error message) doesn't appear to return much.
