Additional Install Information:
6.2 ACTIVATING IBM 31-BIT SDK FOR Z/OS, V5
6.2.1 HFS EXECUTION
If you choose to have the HFS in which you have installed IBM 31-bit
further tasks are required to accomplish this.
IBM 31-bit SDK for z/OS, V5 is invoked as a command under the UNIX
System Services shell. The path environment variable must be updated
to point to the Java executables so that the command will be found.
This can be done with the following shell command:
export PATH=/usr/lpp/java/J5.0/bin:$PATH
The export command references the default path into which IBM 31-bit
SDK for z/OS, V5 was installed. If you changed the default path,
change the export command accordingly.
Alternatively, you can add the IBM 31-bit SDK for z/OS, V5 path to the
system path variable contained in "/etc/profile".
Once the path environment variable has been set, you can enter the
following shell commands:
java
java -version
IBM 31-bit SDK for z/OS, V5 is successfully installed if the "java"
command responds with a summary of available options and the version
option responds with the current version of the IBM 31-bit SDK for
z/OS, V5 code.
This version wasnt mounted and the directory entries on USS empty...

I just ran into a java issue doing an install that required. The HFS file was
not mounted....i had to mount it in USS and then tried it and it worked fine.

Subject: Deeper java problem
Replying to my first post about a Java compile
program, several people suggested it was a
codepage issue. And that was my first thought,
too, since I had been experimenting with
various code pages in my emulator.
However, with codepages matching in both the
old and the new system, I cut and pasted from
the old to the new and reran the compile. Same
result.
Michael Klaeschen suggested I check file.encoding
and the symbol IBM_JAVA_OPTIONS, but I can't find
those. I'm just issuing the javac command directly
under omvs.
More disturbing, I did a cd to the JAVA_HOME directory:
cd /u/Java6_31/J6.0
And an 'ls' showed:
-rw-r--r-- 1 TCPIP IPGROUP 425 Jun 3 22:39 HelloWorld.class
drwxr-xr-x 2 TCPIP IPGROUP 8192 Mar 14 2008 IBM

-rw-r--r-- 1 TCPIP IPGROUP 9084677 Jun 3 22:19 src.zip
drwxr-xr-x 5 TCPIP IPGROUP 8192 Jun 3 22:40 standard
But when I tried to run the sample, here is what I got:
java HelloWorld.class
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld.class
Caused by: java.lang.ClassNotFoundException: HelloWorld.class
at java.net.URLClassLoader.findClass(URLClassLoader.java:419)
at java.lang.ClassLoader.loadClass(ClassLoader.java:643)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:345)
at java.lang.ClassLoader.loadClass(ClassLoader.java:609)
Could not find the main class: HelloWorld.class. Program will exit.
just to be sure, I looked at PATH and CLASSPATH:
printenv PATH
/u/Java6_31/J6.0/bin:/usr/lpp/pli/bin:/usr/lpp/internet/bin:/usr/lpp/cobol/bin:/bin:.
printenv CLASSPATH
/u/scomsto/CGI:/u/scomsto/public_html/Java:/usr/lpp/internet/server_root/cgi-bin:/u/Java6_31/J6.0:/u/Java6_31/J6.0/src.zip:.
In both cases, the '.' at the end should ensure a search
in the current working directory. And I was running in
the JAVA_HOME directory. And I can see the class right
there before me.
Any suggestions at this point?
