There is a Web-based application(JSP) on a Websphere application server in a CICS environment, newly developed....

Also, there is a CICS application using COBOL running in the same environment. This application accesses as Web based in the HTML form after "screen scrapping." This is integrated with the WALKER system.
The question here is, how do you place the link in the CICS application in order to access the JSP deployed on the Websphere application server in CICS environment?
So, you want a CICS transaction to do some CICSy work and then execute a JSP running inside WebSphere?
Hmmmmm, I don't think this is going to be easy. CICS does not really like executing things outside of its own environment and especially things like JSPs. I'd also worry a bit about the UnitOfWork characteristics.
Only two ways spring to mind:
The first is to use the MVS sockets interface to send the required flow to WebSphere. Not as easy as it sounds as you will have to fully format the flow and unravel what comes back to extract the reply.
The second is to code up an EJB wrapper for the JSP and then you can write a Java class (so you can XC LINK to it) that can then issue the call to the JSP via its EJB wrapper.
If the JSP is not doing too much WebSphere or display specific work, then you could redeploy it within the CICS environment as a Java EJB or class that would solve the communication problem.
Also, have a look at the outbound part of the CICS SOAP SupportPac available via the CICS Web Site. This may be of use if XML is used by the JSP.
