Hi!

I am looking for the help on the following aspect.

Team A has a job which runs monthly and generate an XML file through batch cobol program and will send this XML file as an e-mail attachment to team B. Team B will do updates in their database based on this XML manually.

Now Team B is developing a java service to do the update in database automatically.

My question is
Team A has to call the java service using Mainframe Batch COBOL program. Please help me how can this be achieved?

Request input will be : XML file.
Response from java service will be : 'Confirmation Successful'

Thanks & Regards,
Vishwa

Also, you might Google on "z/os cobol and java" and start with the very first link.

On the other hand, per your description - I'm bit confused when you say, "Team A has to call the java service using Mainframe Batch COBOL", why it's needed? What Team B will do then? And Team B is on zOS or ...?

Good afternoon to all!

I am not comfortable with calling webservice to access a java service to process an XML record. One thing for sure is that if this java service executes other services and one service is not available then your java service will not process your XML record. If there's already an XML file generated by a COBOL batch program then is better to add a step to FTP the file to a server where the java program will process the file and update the database.

Are the COBOL program and the Java program running on the same machine or different machines? If different machines, what will the Java code be running on, and how will the COBOL program start it (since one machine starting a program on another machine is possible but usually has organization and security implicaitons)?

The manuals have a sample COBOL OO program that interfaces to a Java program. I got that running, but it took quite a few weeks and some major research -- the process is nowhere nearly as easy as the manual implies it is. And that was for a COBOL program and Java program running on the same LPAR on the same machine!

Gosh and this is what IBM refers to as "Progress" and "Seamlessness"?

Back to the saying "Anything is easy as long as you don't have to do it"?
