Our JAVA folks are using WebSphere. We are trying to get an interface up and running. Most of the existing interfaces use a single record layout, like "give me the current balance for customer 99", and they get back "Balance is $100."
This time there are many different layouts, in a hierarchical format:
ACCOUNT
--CUSTOMER 1
----TRANSACTION 1 A
----TRANSACTION 1 B
--CUSTOMER 2
----TRANSACTION 2 A
----TRANSACTION 2 B
Now, there can be a varying number of CUSTOMERs and TRANSACTIONs. There can be NO transactions.
What I'm hearing today is that we'll need to create a single copybook:
| Code: |
01 ACCOUNT
05 CUSTOMER-COUNT PIC 9(5).
05 TRANSACTION-COUNT PIC 9(5).
05 CUSTOMER-RECORD OCCURS DEPENDING ON CUSTOMER-COUNT.
10 ACCOUNT-KEY PIC X(10).
10 CUSTOMER-NAME PIC X(15).
05 TRANSACTION-RECORD OCCURS DEPENDING ON TRANSACTION-COUNT.
10 CUSTOMER-KEY PIC X(10).
10 TRANSACTION-INFO PIC X(15).
|
So we'll have to separately table each record type so we have a count, then set up the variable length copybook and send it in a single ISRT to the IO-PCB.
This would allow the JAVA folks to use the "wizard" to build JAVA objects for the reply message. They will then take that info and convert it to XML.
I think this is weird. We are taking a hierarchy, flattening it out to transport it, then converting back to a hierarchy.
Is there a better way to handle this using IMS Connect and WebSphere? |

Follow up.
We can also send XML straight out of our IMS program. It's new, so there wouldn't be a lot of extra effort to do it.
The question then would be, can you grab that in JAVA using the WebSphere tools?
I'd want to send each record as a separate ISRT to the IO-PCB, allowing for the levels by sending the closing tags as needed. |
