130 z/TPF and WebSphere Application Server in a Service Oriented Architecture
Figure 7-29 Preparing the JSP to add the service results
A new icon is placed at the location in the JSP where the results will be displayed, as shown
in Figure 7-30. The properties of the inserted expression item allow us to specify what result
we want to display — in our case, the hour value of the current z/TPF time. When we invoked
the service as part of the scriptlet above, we specified to have the results stored in the
timeResp variable. That is where we can retrieve the hour value now, shown in Example 7-3.

We continue the same pattern to retrieve the other values and display them as shown in
Figure 7-31.
Figure 7-31 Completed JSP
By clicking the Source tab of the JSP editor window, we can look at the HTML/JSP code that
makes up our JSP. The code should look similar to Example 7-4.
