After working on your artifacts using the Tooling environment, you bundle them into Composite Applications (C-Apps) that can later be deployed in the server. The steps below describe how to bundle your artifacts into a C-App. When deploying via the management console, you will need to create a Composite Application Archive (CAR) file. See Creating a Composite Application Archive (CAR) file.

Also, you can package individual artifacts into separate C-Apps as well. See Packaging individual artifacts into separate Composite Applications.

  1. Open the Tooling interface with all the artifacts/projects that you created. For example, shown below is an ESB mediation sequeance created with ESB artifacts.
  2. Right-click the Project Explorer and click New -> Project.
  3. From the window that opens, click Composite Application Project.
  4. Give a name to the Composite Application project and select the projects that you need to group into your C-App from the list of available projects below. For example,
  5. In the Composite Application Project POM Editor that opens, under Dependencies, note the information for each of the projects you selected earlier. You can also change the project details here.

Creating a Composite Application Archive (CAR) file

To deploy a C-App via the product's management console, you will need to first create a Composite Application Archive (CAR) file of that C-App.

  1. To create the CAR file, do one of the following:
    • Right-click the C-App project and select Export Composite Application Project from the pop-up menu. 

                      OR

    • Open the pom.xml file in the Composite Application Project POM Editor and click the button for creating an archive in the upper-right corner.
  1. Give the location of the CAR file and the artifacts you want to include in it.

    Tip: When you create a CAR file with artifacts, ensure that each artifact name is the same as the relevant artifact file name.

You have now exported all your project's artifacts into a single CAR file. Next, deploy the Composite Application in the server.

Note

  • In a CAR file, if a particular artifact name is different from the relevant artifact file name, re-deploying the CAR file fails with an error.
  • If a CAR file has one or more artifacts that have a artifact name different from the relevant artifact file name, removing those artifacts from memory fails when you delete the CAR file.

Packaging individual artifacts into separate Composite Applications

You can also create separate deployable artifacts for each individual artifact in your project. For example, suppose you created an Apache Axis2 Service. When you right-click the Axis2 Service Project, there is an option called Export Project as Deployable Archive. It creates the relevant deployable archive in a location you specify.

Following are the deployable archives that will be generated for each artifact type.
