This article discusses whether a CICS application can be deployed as a web service using the CICS Transaction Gateway.
Resolution:
This is possible and the options are:
1) If your code has EXEC CICS statements then you will have to use MTO. This is not optional. If the CICS commands are no longer needed then you will need to code alternatives and/or comment them out.
2) A COBOL web service cannot contain EXEC CICS statements because this is not currently supported. However, you can run both web services and CICS applications at the same time under Enterprise Server. Therefore, you can have a web service that invokes a separate CICS transaction via EXEC CICS LINK. This feature is called the "CICS Transaction Gateway" and is documented in chapter 11 of the Mainframe Transaction Option (MTO).
