Is TIBCO necessary to retrieve XML from CICS?
No. Any application (e.g., .NET, VB, Java) can send a request directly to HostBridge. In fact, this is how the vast majority of our customers use HostBridge: their application sends an HTTP request to HostBridge, and HostBridge returns the output from the transaction as an XML response. The bottom line is that the services of HostBridge can be invoked by any application that can send an HTTP request and receive/process and XML document. The value of TIBCO is not the XML-enablement of your existing CICS apps (that’s HostBridge’s job). Instead, TIBCO creates a real-time, message-based infrastructure so that disparate system/application platforms can communicate. TIBCO is one way, but not the only way, for an application to request the services of HostBridge.
