Your First BizTalk Server Integration 1. 53 If you have not already done so, create the test folder structure corresponding to the configu- rations performed in the Orchestration: a folder named MyFirst off the root of the C drive, with child folders In, ExecOut, and EmpOut. Copy sample_employee_grade2.xml and paste the copy into the In folder. After a few seconds, the file should disappear. Check ExecOut and ensure that it remains empty. Open the file that appeared in EmpOut and note that it is a copy of the message you dropped. Repeat steps 2­4 with sample_employee_grade7.xml. This time, both outbound folders will have a message. Open the one in ExecOut and note that it is an executive instance whose data corresponds to that in the original employee message. Note that the fname and lname attributes have uppercase values. 2. 3. 4. 5. Summary BizTalk Server 2004 has an extensive architecture that rests, as you have seen in this chapter, on two core runtime engines. Messaging handles low-level message exchanges with data transfor- mation and protocol-switching capabilities. Orchestration is a sophisticated and powerful workflow processing engine that relies on the messaging engine for the implementation of the individual actions in the workflow. Designers and developers working with BizTalk Server 2004 rely on a series of add-ins to Visual Studio .NET for their development tasks. This is a consolidation of the tools from earlier versions of BizTalk Server and represents a considerable improvement in that developers are able to stick with a single, familiar IDE.
