'java.lang.Object' cannot be found

Thanks Alan and Bruce, but the problem remains.

Okay, I have three directories containing /usr/libexec but sadly none of them contain any file or directory named java_home.   In fact, Finder does not admit to having a java_home file anywhere.

You need to locate that to find the Java run-time JAR file (classes.jar in my environment but I've also seen rt.jar in other Java implementations. - Trust but verify...)

Okay, but nowhere on my OSX system do I see either a rt.jar or a classes.jar.   

The only likely jar file I can find is JavaTools.jar, and I've tried this without success.

Java on OSX has changed on 10.5, the newer java version only runs on intel hardware whereas my machine has a ppc processor.

I'm sure the solution is really simple.   I just don't know where to look.

Thanks Bruce, I did what you told me to do, and used your supplied script.    But I still get exactly the same problem:   

NetRexx portable processor, version 2.05

:

Program hello.nrx

   +++ Error: The class 'java.lang.Object' cannot be found

Compilation of 'hello.nrx' failed [one error]

:

What and Where is the class 'java.lang.Object' and how do I get the Rexx compiler or Java (whichever needs it) to find it?

Thanks.

Connor.

Hi Connor,

NetRexx runs on every MacOSX release on PPC also. Do note that Finder does not show all 'system' kind of files by default.

If you open a Terminal window, and type:

java -version

and that gives you an answer, you know that java.lang.Object is somewhere.

then do a

cd /System/Library/Frameworks/JavaVM.framework/Classes

and look at the .jar files in there.

Alternatively, 

cd /System

find . -name classes.jar

will show you (after some time, it scans all files) where classes.jar is located. Put this on the classpath and you are ready to go.

best regards,

René Jansen.
