Hi All,

Is it possible that any user put input through some web panel (designed in JAVA) and the JCL be created in mainframe may be through REXX and then finally the output summary be reverted back to the user.

I short is there any mean to separate user from mainframe and yet let them provide means to input to the mainframe.

Thanks

Yes, but it is way beyond my ken.... icon_confused.gif
I do know that all the needed pieces are in play and available but I don't know specifically how.

Good luck,

Bill

For what it's worth, I'd start at IBM's Redbook site...ibm.com and search on redbooks...

Do you have MQ Series setup, if this infrastructure is available then it'll be easy and can be real time interface b/w Web and Mainframe.

Suppose you dont have MQ Series setup then there is another way in which you can get inputs from Java apps and create and submit JCL for processing.

Reply back your options

Hi Devzee,

I am afraid that I do not have MQ series setup. Actually I dont know much about these setup. I am working on mainframe and this is a new request even I know JAVA only a bit.
Will it be possible for me to implement it?

Thanks

Alright If you dont have MQ, then you can try this option.

You can develop Java class and get user input from Java Apps and then do FTP put command to trigger the JCL on Mainframe. The job gets processed on Mainframe say it takes 5 minutes to process and create an extract file. From Java class try to do FTP get extract file, if the file is in-use (currently being created by the execution JCL) then keep re-try until you get the extract file.
Display and format the file in Java Class.
