Hi all,

I am trying to call java in C on Zos, from the webpages I come to know about of the jni header file.Even after including the header file in system libraries I cant able to execute, it throws a jcl error .Is there any specified compiler program to call java in C.It will be very helpful for me if you share your knowledge.

Thanks in advance!!

Hello and welcome to the forum,

You need to post the JCL and the error raised.

And please note: JCL errors are NOT thrown. Jobs FAIL with JCL errors or they are NOT RUN. Java and C code 'throw' errors which they, hopefully, 'catch' but when they terminat with an error they abend or fail but the word thrown is not used externally.

Error

N1-JCL ERROR CN(INTERNAL)

1 - there are more error messages somewhere relating to the JCL error
2 - your PROC has MEM= but there is no &MEM within the procedure
3 - you have

Select all

//SYSCIN DD

whch is an invalid DD statement as it is - if it was the start of concatenation override then it could be valid

but without the error messages we can only guess.

the PROC will hold the member name,it is declared at the bottom.SYSCIN is for DBRMLIB.

*if it was the start of concatenation override then it could be valid i cant able to get it properly.

If your JCL is as you posted, then you have a GREAT deal of work ahead of you. I had assumed you redacted the data set names for security purposes but if not, each DD statement needs -- at a minimum -- a data set name and disposition (DSN=?,DISP=?) and possibly more information. You must also specify input to the PC step (usually //SYSIN DD DSN=?(&MEM),DISP=SHR or something similar). And no, we cannot tell you the data set names since they are specific to each site and anything we told you would most likely be wrong. You must contact someone working AT YOUR SITE to get those details.
