Enabling SOA Using WebSphere Messaging

Chapter 7. Integration scenarios with WebSphere Message Broker 265

7.6.2 Define the filters

To do this:

1. Right-click the first Filter node (Skypass) and select Open ESQL. Change

the ESQL code as shown in Figure 7-2.

Example 7-2 ESQL code for Skypass filter

CREATE FILTER MODULE Filter1

CREATE FUNCTION Main() RETURNS BOOLEAN

BEGIN

If Root.XML.CustomerOrder.FlightInfo.Membership = 'Skypass'

Then Return TRUE;

Else Return FALSE;

End If;

END;

END MODULE;

2. Open the ESQL for the second Filter node (Morning Calm). Note that the

ESQL for both Filter nodes is kept in one file. Change the ESQL code as

shown in Figure 7-3.

Example 7-3 ESQL code for Morning Calm filter

CREATE FILTER MODULE Filter2

CREATE FUNCTION Main() RETURNS BOOLEAN

BEGIN

If Root.XML.CustomerOrder.FlightInfo.Membership = 'Morning Calm'

Then Return TRUE;

Else Return FALSE;

End If;

END;

END MODULE;

The resulting definitions should look like Figure 7-49 on page 266.
