I have installed java SDK 1.4.2, 1.4.1 & 1.3.1, plus NetRexx 2.02 on Win2k.
I ran java demos successfully (eg. bigdecimal in v1.3.1 runs fine under
1.4.2), but NetRexx hello sample fails in each version (I started with
1.4.2 & worked back through older versions to see if I might've had a
NetRexx/new-java incompatibility). I've gone over install doco several
times, NetRexxC.jar is in java's jre\lib\ext (all versions). Sample output
is here (notice that 1.3.1 error is slightly different):

Re: java.lang.Object not found

Mike Cowlishaw-2
This is due to the IBM 1.4 JVM having renamed rt.jar

NetRexx 2.05 reads *all* jars in the library, so is a little bit slower
starting up, but works around this problem.   (Or you can copy core.jar,
etc. to ...\lib\ext.)

NetRexx 2.05 can be downloaded at:

   http://www-306.ibm.com/software/awdtools/netrexx/nrdown.html

sun/tools/javac/Main not found

Thanks, NetRexx 2.05 gets around the java.lang.Object not found error.  Now
I get the same error in 1.4.2 that I reported in 1.3.1:

That one's covered in the User's Guide.   Sun moved the .jar with
javac out of the search order, so the JVM cannot find it.  Best
fix is to copy the tools.jar to   lib\ext.

Thanks, that worked.  However, if you're referring to the following
paragraph on p5, it's an either/or statement and the CLASSPATH option
clearly doesn't work.  Perhaps the User Guide needs to be updated.

"3. If you are running Java 1.2 or later, make the file \lib\tools.jar
(which contains
the javac compiler) in the Java tree visible to the JVM. You can do this
either by
adding its path and filename to the CLASSPATH environment variable, or by
moving
it to the jre\lib\ext directory in the Java tree."

Re: sun/tools/javac/Main not found

Mike Cowlishaw-2

It does work for some people, and it did work for me, when I was in 1.2.   So 'clearly' is a bit strong... :-)

Unfortunately it is almost impossible for me to update site/doc now as it is 'owned' by ibm.com.   Took almost 3 months to get 2.05 zip out there :-(
