Enabling SOA Using WebSphere Messaging

222 Enabling SOA Using WebSphere Messaging

This perspective is used to develop and test message flows and message sets.

You can see in Figure 7-1 on page 221 that the perspective consists of views

designed specifically for development. The Resource Navigator view (top left)

lists the message flow resources. The editing area (top right) contains the canvas

where nodes are placed in the flow, node properties are set, and the nodes

connected together. Nodes can be placed on the canvas using drag and drop

from the Pallete. The Problems view (bottom right) shows informational, warning,

and error messages that indicate problems within resources. The Outline view

displays a structured outline of the file open in the editor area (palette).

7.1.2 Message flow deployment and broker administration

Message flows are packaged into broker archive (bar) files and deployed to

execution groups on a broker. An execution group is a named grouping of

message flows that have been assigned to a broker. The broker does the actual

processing of the message flow.

The Message Brokers Toolkit provides broker administration functions through

the Broker Administration perspective (Figure 7-2).
