Hi,
I saw that Netrexx runs on Mac OS, so I thought I would try it again. I gave up in the past, because I couldn't translate the instructions into "Mac". On the Mac I have put both of the jar files in the "Extensions" folder, i.e. /Library/Java/Extensions. When I run the NetRexxC.sh script, I get the following. NetRexxC.sh ../hello + test 1 -eq 0 + test ../hello = -run + java -ms4M COM.ibm.netrexx.process.NetRexxC ../hello NetRexx portable processor, version 2.05 Copyright (c) IBM Corporation, 2005. All rights reserved. Program hello.nrx +++ Error: The class 'java.lang.Object' cannot be found Compilation of 'hello.nrx' failed [one error] + test 2 -eq 0 So it looks like it is finding the compiler. Can someone tell me what it is looking for? Thanks, Bruce -------------- next part -------------- An HTML attachment was scrubbed...

Hi Bruce,
It's looking for the Java core classes. 'Object' is the actual root of java's class library. Have not much experience with java on Mac OS X but a known location for this is /System/Library/Frameworks/JavaVM.framework/Versions/1.5.1/Classes/classes.jar Definitely, you should look for the 'classes.jar' file Hope that little bit helps somewhat. 2010/2/3 Bruce Skelly <[hidden email]> > Hi, > > I saw that Netrexx runs on Mac OS, so I thought I would try it again.

Thanks that gives me something to look for.

Hi Bruce,
sorry for being late to the party, but I am in CET (Amsterdam). What you should have on your classpath for 2.05 is: /System/Library/Frameworks/JavaVM.framework/Classes/classes.jar the Snow Leopard default command line java seems to be 1.6 - this path always points to the current one. The good news is that what is packaged in tools.jar is also in classes.jar on the Mac. This problem will eventually go away, as I happen to know. best regards, Ren? Jansen.

Hi Ren?,
I'm on Leopard (Mac OSX 10.5.8), so it appears that my default version of java is 1.5.0_22. I added a CLASSPATH=/System/Library/Frameworks/JavaVM.framework to the NetRexxC.sh shell script. Now it appears that the "compile" is looping. I'm getting 90% cpu for Java, and waited several minutes for hello.nrx to "compile" before canceling it. Any suggestions?

I tried that and I get the same error I was originally getting.
I usually think of a CLASSPATH as consisting of directories, not jar files. I also tried the path less the end, classes.jar, but that also died with the original error message. I also, due to recent conversations, took the '-ms4M' out of the command line with no effect. Thanks for the suggestions, and keep thinking. I've got to be close, if it is looping.

Bruce,
as David stated, the classpath must contain what is stated - including the jar. It now will parse the large java archives in that directory. Generally, when compiles take very long, it is worthwhile to make a subdirectory - if there are a lot of java classes on your system, and these can be 'seen' from the classpath setting, the compiler will process them each time In this case this is not needed, because the classpath itself is at fault. best regards, Ren?.

Bruce,
with classpath issues it helps to move the things that you know are good to the left. So the NetRexxC.jar first, then the Java runtime, and then the rest. Try to move your source to a runtime. Maybe add a -verbose5 to the compile to see if that yields any clues. Warning: -verbose[0-5] lives up to its name. I have run NetRexx on all available MacOSX versions since 2003 and only recently moved all machines (but one, the PPC mini) to Snow Leopard. It did not give me any trouble on Leopard at all - we must be close. Maybe show the relevant statements from your profile so we can see. We will get this to work soon. best regards, Ren?

Ok, my mistake. When I used the path that you provided, I *thought* I
got the same error message. I didn't.

Warning: > -verbose[0-5] lives up to its name. Ok, but what constitutes the Java runtime? Why does it have to be in my CLASSPATH. I can, without a CLASSPATH, launch a Java app buy just running the jar file, i.e. open -a some.jar. So the OS must have a built in default way to find the runtime. Note that I was getting the compiler to launch simply by putting it in /Library/Java/Extensions. Another example, I can compile and run the following program from the command line with *NO CLASSPATH*. // MyProgram.java public class MyProgram { public static void main(String[] args) { System.out.println("Rome wasn't burned in a day!"); } } All I need to do is to type javac MyProgram java MyProgram hello.nrx isn't much more complex, is it? So I don't understand why I should need a CLASSPATH to find classes.jar. If CLASSPATH is the only way to get this to work, that's what I need to do, but I feel that I'm working against the OS.

The core clases in the java clas library plus som classes in sun.* packages > Why does it have to be in my CLASSPATH. Just to allow the jre know where they are in oder co call it methods, etc. Until java 1.1 you had to define a CLASSPATH environment variable to inform de jre where its own standerd classes where located. Since java 1.2 there is an implicit classpath including them.

Puting it inside the Extensions directory is just another means of acomplishing this. Then the compiler generates a java file as an intermediate step. Finally the compiler calls the java *compiler*, with that file to get the final bytecode. On most platforms the java compiler and supporting classes, etc. are located at a certain Tools.jar file which *is not* part of the jre nor is it included by default in the implicit classpath. So you have to include tools.jar in the classpath... On OS X this is different as what would be the contents of tools.jar is included inside classes.jar (the core java class library) > If CLASSPATH is the only way to get this to work, that's what I need to do, > but I feel that I'm working against the OS. I have no experience at all in OS X so can not tell you why it is not working. Hopefully, having more info on how things actually work may help you figure it out. -- Saludos / Regards, David Requena -------------- next part -------------- An HTML attachment was scrubbed...

In addition to what David already said, java has an easy time finding its runtime because it is, by virtue of being installed by its own installer, always in the same relative path to the native program that kicks off the interpreter. It is not the OS, it is actually the Java implementation that knows where it put its classes to load.
But you are right, and it might be that a future version of NetRexx that I cannot speak about will run without a classpath setting on Mac OSX - this by virtue of Apple putting this in predictable and stable places. This also goes for z/Linux and other OSses where a single vendor controls the library locations. The tools.jar requirement is not for the Mac - on Mac OSX the compiler classes that you need are also package in classes.jar. Looking at the message in your previous email, it looks like that you do not have NetRexxC.jar on your classpath. It does find the compiler, but not the runtime; that is slightly odd. Maybe first put NetRexxC.jar on the classpath, and then try this: java COM.ibm.netrexx.process.NetRexxC hello.nrx this should yield a hello.class file, that you can run with java hello I have an executable (chmod +x nrc) shell script file called nrc on my system, in the PATH, that consists of one line: java -Xms128M -Xmx256M COM.ibm.netrexx.process.NetRexxC $* (the extra memory is for being able to compile way-too-big projects) and the classpath in my shell profile. good luck, and let me know if it does not work. best regards, Ren?.

Ok, here is a "verbose" of what I'm doing. As you can see it is
looping until it runs out of memory. See comments in line. Bruce P.S. This is the third attempt to send this, due to message size limits on the list server. I have severely trimmed the output.

Hmm... That's very odd, you're running out of heap ram just by loading the compiler.
As far as I know there ins an absolute minimum of 2mb in java 1.5 but real initial heap is affected by amount of installed physical ram. How much that be in your box? You could try passing increasing minimum heap values to the jvm with the -Xsm option. Definitely this shouldn't be necessary under usual circumstances for helloworld type programme.

Hi folks,
This is a non-technical observervation.... But, It seems the looping (i.e, "Repeated a total of 29 times.") is occurring after an out-of-memory exception occurs. However, previous to the out-of-memory exception, there appears no looping, but just normal, (but numerous) loads of various service classes. I'm not sure what the behavior of netRexx is should it run out of memory at that exact point (hard to reproduce). I also sorted your java class load sequence (from your previous email) looking for duplicates....and each class is loaded once, so it doesn't appear to be looping at all (I don't' see multiple load attempts of various classes). Perhaps your system is seriously memory constrained at the time of the compile, or perhaps your shell/process is restricted in some other way? Just a thought...

Yes, I'm running out of memory, but I don't think that is the problem.
I have 4GB of memory, and a 2.53GHz Core 2 Duo. The command runs for more than an hour and 20 minutes before running out of memory, so giving it more memory would just make it run longer in my opinion. The 'javac' command to compile a java version of "hello world" takes less than a second. I just want to mention that this is with NO CLASSPATH set. I would think that if it couldn't find something due to a path problem, that it would just error out and fail. As you can see with no CLASSPATH, the java interpreter is find classes.jar just fine. Also, I don't think I'm getting to the point where output is created, as there is no hello.java file being created. At least not in the same directory as the hello.nrx.

As I mentioned to David, I think that if it was a memory issue, it
wouldn't take over an hour (it's now been running over an hour and a half) to run out of memory. I think the looping is happening in just one class, perhaps just one statement, and therefore you would see each class being loaded only once.
