    Hello Community,

    I am curious to know how companies has solved making REST-calls from COBOL programs running as IMS-transactions. There is Web Enablement Toolkit of course. Is that what people are using? It's quite a lot of code needed for something that should be simple. I am also thinking of letting a Java program make the http request. Have any of you any experience using the new COBOL<->Java support in COBOL 6.4?

    Not exactly what you are asking, we (my former company) were doing outbound calls from CICS and use z/OS Connect to do that.  I'm pretty sure you could do the same from IMS, but yes it's an additional product to buy, install and support if you don't already have it.  We already used it for inbound API calls, so that wasn't a concern.

    Thank you, Gregory!

    We are not using z/OS Connect since we have our own home-grown solution for inbound API calls (that is really good!).

    COBOL-Java-integration is an interesting topic in its own right. Has anyone tried the new functionality introduced with COBOL 6.4?

    Are there more (better?) ways of making outbound API calls from within transactions?
