getting crazy with this java-classpath-lib-doesnt-work-whereever-i-put NetRexxC.jar-thing :-((((

Hi @all,

still trying to get NetRexx running - but no way - i'm thinking of the good
old past times where REXX just runs by typing rexx <rexx-programfilename>

My environment:
I use the newest package called NetRexx-3.01RC2.zip
OS installed: Windows Server 2008 R2 x64
Java-Version used: java version "1.6.0_30"
Java(TM) SE Runtime Environment (build
1.6.0_30-b12)
Java HotSpot(TM) Client VM (build 20.5-b03, mixed
mode, sharing)
Java is installed here: C:\Program Files (x86)\Java\jre6
The NetRexxC.jar ist here: C:\Program Files (x86)\Java\jre6\lib
NetRexx is installed here: C:\NetRexx
my PATH-variable contains: ...;C:\NetRexx\bin

There is no CLASSPATH-variable and according to some java-forums it seems
not recommended to create one anymore.

I'm working page per page with the book "NetRexx User Guide September
1st,2011 Version 3.01", currently hanging on page 21.
If i try to run the hello.nrx program, this happens:

C:\NetRexx\examples\ibm-historic>nrc -run hello.nrx
Exception in thread "main" java.lang.NoClassDefFoundError:
org/netrexx/process/NetRexxC
Caused by: java.lang.ClassNotFoundException: org.netrexx.process.NetRexxC
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: org.netrexx.process.NetRexxC. Program will
exit.

Does anyone can help me?

Thanks in advance,

Kind regards,
Christian Schaper

Hi Christian,

my advice would be to put in a CLASSPATH variabe in your environment, making sure that

1) NetRexxC.jar (the full path to)
2) tools.jar (idem)

are on it. Working without a classpath is in theory a possibility, but has practical drawbacks.

Let us know how it goes - we will make it work.

best regards,

René Jansen.

Hi Christian,

You will have to put the NetRexxC.jar into the ...\lib\ext\
subdirectory of
of your proper JDK.

I use this technique for years to avaid the need o any classpath at all!

When that does not work, give me a phone call tomorrow, 10:00 - 19:00
o'clock: +43/1/20 85 195

and we can check it out whilst you and I are on the computer :-)

Welcome Christian --

While modern Java does not need a classpath to find it's own files, that
is not true for 3rd party applications. Both NetRexx and your own
programs will need a classpath to allow Java to find them. The CLASSPATH
environment variable is not recommended these days because it can cause
conflicts in applications with different path requirements. Each Java
application should now have it's own classpath specified in the Java
startup command. For example, you could add "-cp
.;c:\NetRexx\NetRexxC.jar" to the java commands in your NetRexxC.bat
file before the other operands.

There is also a Java program you can download and run to display all
relevant environment info:

http://kenai.com/projects/netrexx-plus/downloads/download/Envirotest/envirotest.class

run with

java envirotest

and post results and someone can help with any classpath issues.

Thomas,

Talk about putting your money where your mouth is... You are the best!
This is about the greatest, finest example of NetRexx support that I've
ever seen. God Bless.

P.S, I do the same madness at work with our customers. Works every time.

Have a good day, Sir.

Re: getting crazy with this java-classpath-lib-doesnt-work-whereever-i-put NetRexxC.jar-thing :-((((

Today I discovered that you have to have the very subdirectory for tools.jar in the classpath in order for netrexxc to find javac This is a nice list of your CLASSPATH: . /media/2f4b8239-4437-4487-8850-12e240f34e98/netrexx/lib/NetRexxC.jar /media/2f4b8239-4437-4487-8850-12e240f34e98/ /usr/lib/jvm/java-6-openjdk/* /usr/lib/jvm/java-6-openjdk/lib/* Without that last line nrc failed by not finding the javac compiler.
