Processing messages and synchronizing transactions
IMS message-processing applications must do all message processing and transaction synchronization either in COBOL or Java™, rather than distributing this logic between application components written in both languages.
About this task
COBOL components use CALL statements to DL/I
services to process messages (GU and GN)
and synchronize transactions (CHKP). Java components use Java classes for IMS to do these functions. You can use object
instances of classes derived from IMSFieldMessage to
communicate entire IMS messages
between the COBOL and Java components
of the application.
