Chapter 1. Deploying a Web Service into Red Hat JBoss Fuse

Abstract

Here we will take an in depth look at the CXF OSGi example, a JAX-WS web service packaged as an OSGi bundle.
You are going to build and deploy a simple service that is based on a WSDL document. The source for this example can be found in the InstallDir/examples/cxf-osgi folder of your Red Hat JBoss Fuse installation.
The example uses the JBoss Fuse Maven tooling to build a bundle that contains the service implementation and all of the metadata needed to deploy it into the JBoss Fuse container.
The sample code includes a web page, client.html, that will allow you to access the service once it is exposed.

1.1. Deploying the Example
Copy link

Before you run the example, start Red Hat JBoss Fuse.

Installing a prebuilt version of the example
Copy link

To install and run a prebuilt version of this example, enter the following command in the Red Hat JBoss Fuse console:
features:install examples-cxf-osgi

Building and deploying the example yourself
Copy link

To build and deploy the example do the following:
  1. If you installed the examples-cxf-osgi feature, first uninstall it by running the following from the Red Hat JBoss Fuse console:
    features:uninstall examples-cxf-osgi
  2. In a separate command window or terminal, change to the root folder of the example.
    cd InstallDir/examples/cxf-osgi
  3. Enter the following command: 
    mvn install

    This command will build a bundle called cxf-osgi-6.0.0.redhat-024.jar and place it into the target folder of the example.
  4. Copy the bundle to InstallDir/deploy to deploy it to the container.

Testing the example

To see if the example is running you can visit http://localhost:8181/cxf/HelloWorld?wsdl in your Web browser. You should see the WSDL shown in Example 1.1, “CXF OSGi Example WSDL”.
