Hi group,

I was trying to invoke a java executable file using the below batch but The expected output was not recieved. The out out was expected to throw as "HELLO WORLD" but there was no luck.

Could Anyone please throw some light on this issue.

Also, i have implemented the JZOS tool kit to run this java codes but the manuals are not still clear about mentioning the JAVACLS parameters.

The system is telling you, quite clearly, what is wrong:

STDOUTL :


Usage: java Ý-options¨ class Ýargs...¨
(to execute a class)
or java Ý-jar¨ Ý-options¨ jarfile Ýargs...¨
(to execute a jar file)

compared to

//RUN EXEC PGM=BPXBATCH,
// PARM='SH java -cp /proj2/jproj/path.classpath'

Since you did not provide any Java program for the system to execute, it did not execute any Java program. Did you compile your program with JAVAC? If so, and your command was javac HelloWorld (for example), you should execute or possibly but I'd try without the full path first.

Hi Robert,

Thanks for the reply. I tried with the given codes but i got as java class "helloworld" not found and also with second code i got an error as javaclass .proj2.jproj.helloworld' not found. The path i have ftped the java developed codes within OMVS was /proj/jproj/path.classpath and it was not a jar file but it was a classpath file. To run this file are there any constraint ? but the path.classpath file contains the codes for throwing the message as "Hello world"

If your code is stored as helloworld.java, when compiled it becomes helloworld.class and you would therefore issue the command java helloworld to execute the code. I have compiled and executed a number of Java programs using this method. I have never run across anything like "path.classpath" -- class paths are exported in Unix System Services by issuing the export command in your .profile or directly after getting into Unix System Services.

Have you tested in Unix System Services? If not, testing by directly issuing the commands from a Unix System Services prompt will speed up your debugging process by allowing you to make sure the commands work before attempting to use them in batch.

Hi Robert,

I directly executed the command java Hellow.class but i got the below error message :

$ java Hellow.class
The java class could not be loaded. java.lang.ClassFormatError: (Hellow) bad mag
ic number at offset=0
$


Also I gave java Hellow command and i got an error message as : java class not found : Hellow.

Please guide me in this regard.

Regards,
Jaggz

I strongly recommend you start with the basics. It appears your file transfer of the java class failed to transfer a valid java class file for some reason, since the message seems to indicate the class file is not valid. Something like this (in OMVS or via Telnet into the Unix System Services port) should help you confirm what you're trying to do:Once you have successfully been able to do this, then you can look at doing the same via a batch job, then look at the file transfer and so forth. I do not know if java bytecode needs a binary or text transfer -- if you don't know either then that is one key thing you MUST find out. But unless you have successfully tested java interactively, then doing the same thing in a batch job, you will not be able to tell if your problem is a java problem, a JCL problem, a Unix System Services problem, a file transfer problem, or something else.

I was able to execute directly in tso omvs. But while executing througH jcl We got the below error.

Could you please suggest some idea or guidelines

Java requires some parameters in the BPXPRMxx member of SYS1.PARMLIB to be much larger than the defaults IBM provides. You need to contact your site support group and have them adjust the BPXPRMxx member values to allow enough memory for Java to execute. If they have already done this, they will need to open a PMR with IBM to get your problem resolved.

This is NOT an issue an application person can fix -- it must be done by systems support people.
