### Constructing Proxy Service Message Flows

When you create a proxy service, a message flow is created by default, with an empty starting node. The process for constructing the message flow follows this general pattern:

1. Open the Message Flow Editor for the proxy service. To open the proxy service, double-click its name in Project Explorer. The Message Flow Editor appears as a tab in the proxy service view.
2. Open the Message Flow Design Palette. To open the palette, in the ALSB perspective, select Window > Show View > Design Palette.
3. Open the Properties view, if it is not already open:

1. In the ALSB perspective, select Window > Show View > Other.
2. In the Show View dialog, select General > Properties.

4. Drag nodes and actions from the Message Flow Design Palette to the Message Flow Editor.

Alternatively, you can right-click a node or action in the Message Flow Editor to display menus of nodes and actions that can be inserted in that location. The menu contains one or more the following:

- Insert > (list of nodes and actions)
- Insert Into > (list of nodes and actions)
- Insert After > (list of nodes and actions)
- Add Error Handler

5. Configure nodes and actions:

1. In the Proxy Service Editor, select the node or action by clicking it.

Alternatively, you can select a node or an action from the Outline view. To open the Outline view, in the ALSB perspective, select Window > Show View > Outline.

2. In the Properties view, set the properties, as appropriate for the selected node or action. For instructions on how to configure the nodes and actions, click the Properties view for a node or action, and press F1 for help.
