Creating the Organizations and Applications
The first thing to do is create the organizations. Begin by opening the BizTalk Messaging Manager. You can do this by choosing Start, Programs, Microsoft BizTalk Server 2002, BizTalk Messaging Manager.
Note
You might get a message box at this point, depending on whether you just installed BizTalk Server. Click Cancel and follow the directions in the following paragraphs for creating a new home organization.
When the dialog opens, choose Organizations from the list of links under Search for Other Items and click Search Now. A list of available organizations appears in the righthand-panel (see Figure 7.2).
Figure 7.2. BizTalk development environment.
In the right pane, you see the home organization. Double-click Home Organization, and the Organization Properties dialog box opens, as shown in Figure 7.3.
Figure 7.3. The Organization Properties dialog.
First, rename the home organization by entering BigBank_Co as the Organization Name. The Organization Properties dialog box contains two other tabs—Identifiers and Applications. The Identifiers tab allows you to assign multiple name/value pairs to identify your organization. The default value for your home organization is the organization name—that is, the one you just identified in the General tab, but you can add others.
The Applications tab is used to define applications that will be used as either the source or destination point for BizTalk Server. Applications are a logical versus physical distinction available to help you distinguish between applications exchanging data inside the home organization.
Note
You can define applications only for the home organization.
For instance, think of BizTalk Server as being used to integrate two disparate applications inside your organization, one to receive the data from an application to BizTalk (sendData) and another to receive the repurposed data and process it (processData). Both applications (sendData and processData) would need to be added to the Applications tab. In our example, however, we need to add two applications to this dialog box:
receiveTrans
getTrans
In this example, an ASP application, receiveTrans.asp, waits for a message from Sunset Bank, Inc. When a message is received (via HTTP), the receiveTrans.asp application submits it to BizTalk Server (you will see how this happens a bit later).
Next, we need to create a new organization named SunSet_Bank. To accomplish this, select File, New, Organization from the menu. In the dialog that appears, name the organization SunSet_Bank and then save it.
Before we continue, it should be noted that there is an ASP application running at Sunset Bank called sendTrans.asp. The purpose for sendTrans.asp ASP application is to send an XML transaction set to BigBank so that it can be properly processed. Figure 7.4 illustrates the basic flow for this application.
