Building and Instantiating Schedules

The remainder of this chapter will walk you through four complete examples showing the integration of BizTalk Messaging and XLANG schedules and schedule correlation. The examples are for the EAI scenario described earlier in the chapter, essentially integration of two applications (Account Management System and ERP system) using schedule correlation. This will allow you to install and run these applications on a single machine. You can easily extend the examples to a B2B scenario on multiple machines with very little effort.

The four examples involve building five orchestration schedules. Each schedule is simply a revised version of the previous. The first demonstrates how to instantiate a schedule instance from BizTalk Messaging. The second example demonstrates HTTP-based correlation where both the applications have BizTalk Server. The third example demonstrates HTTP-based correlation where one of the applications has BizTalk Server and the other will be running on some non-Windows platform. The fourth and final example demonstrates non-HTTP-based correlation.
