Fuse Tooling starts downloading from the Maven repository all of the files it needs to build the project, and then adds the new project to Project Explorer.

If you are not in the Fuse Integration perspective, the tooling asks whether you want to switch to it now:

Click Yes to open the new CBRroute project in the Fuse Integration perspective:

The new CBRroute project contains everything needed to create and run routes. As shown in Figure 2.1, “Generated project files”, the files generated for CBRroute include:

Drag a File component ( ) from the Palette's Components drawer to the canvas, and drop it in the Route_route1 container node.

The File component changes to a From _from1 node inside the Route_route1 container node.

On the canvas, select the From _from1 node.

The Properties view, located below the canvas, displays the node’s property fields for editing.

In the Properties view, click the Advanced tab:

You need to create a folder for the project’s source data and enter that folder’s name in the Directory Name field.

In the Directory Name field, enter src/data:

The path src/data is relative to the project’s directory.

On the Consumer tab, enable the Noop option by clicking its check box.

The Noop option prevents the message#.xml files being deleted from the src/data folder, and it enables idempotency to ensure that each message#.xml file is consumed only once.

Select the Details tab to open the file node’s Details page.

The tooling automatically populates the Uri field with the Directory Name and Noop properties you configured on the Advanced tab. It also populates the Id field with an autogenerated ID (_from1):

Drag another File component from the Palette's Components drawer and drop it in the Route_route1 container node.

The File component changes to a To _to1 node inside the Route_route1 container node.

On the canvas, select the To _to1 node.

The Properties view, located below the canvas, displays the node’s property fields for editing.

On the Details tab, enter file:target/messages/others in the Uri field, and _Others in the Id field:

In the Route_route1 container, select the From _from1 node and drag it’s connector arrow ( ) over the To_Others node, then release it:

Click the Source tab at bottom, left of the canvas to display the XML for the route. The camelContext element will look like Example 2.1, “XML for CBRroute”:

If you haven’t already done so, download the prefabricated test message files (see Chapter 1, Using the Fuse Tooling Resource Files for instructions). Copy message2.xml through message6.xml into the newly created CBRroute/src/data folder. You will use all six test messages in the remaining Fuse Tooling tutorials.

Table 2.1, “Preconstructed test messages” shows the contents of each remaining prefabricated message file.
