The Broker Application Development perspective provides several views to navigate, browse, and update your application resources.

Navigator view

This view displays a hierarchy view of the following message flow resource files:
  • Message flow projects
  • Message flows

You use specialized editors to open and edit any of these resources, except project files.

Editor view

Double-click a resource in the Resource Navigator view to launch the associated editor in the Editor view.

The Message Brokers Toolkit provides the Message Flow editor by default for working with the content of message flow files.

Outline view

The Outline view provides a summary of the content of the resource that is currently open in the Editor view.

Click the Overview Mode icon The Overview Mode icon to toggle to the Overview view, which provides a useful summary for large, complex message flows because it shows a small-scale version of the flow. Click the Overview Mode icon again to return to the Outline view.

Problems view

The Problems view displays any messages (information and error) that are associated with the resource that is currently open in the Editor view. For example, if you save a message flow that has an error (such as a mandatory property not set), you can check the content of the Problems view to determine any corrections that you need to make. When you double-click a Problems view entry, the appropriate editor opens the resource that contains an error, and positions the cursor at the point of the error (where possible).
