Generating and Running a Web Services Bundle

This section explains how to generate, build, and run a complete Apache CXF example in the OSGi container, where the starting point code is generated with the help of a Maven archetype.

In order to generate a project using a Fuse ESB Maven archetype, you must have the following prerequisites:

The servicemix-osgi-cxf-code-first-archetype archetype creates a project for building a Java-first JAX-WS application that can be deployed into the OSGi container. To generate a Maven project with the coordinates, org.fusesource.example:cxf-code-first-bundle, enter the following command:

The result of this command is a directory, ProjectDir/cxf-code-first-bundle, containing the files for the generated bundle project.

Typically, you will need to modify the instructions for the Maven bundle plug-in in the POM file. In particular, the default Import-Package element generated by the servicemix-osgi-cxf-code-first-archetype archetype is not configured to scan the project's Java source files. In most cases, however, you would want the Maven bundle plug-in to perform this automatic scanning in order to ensure that the bundle imports all of the packages needed by your code.

To enable the Import-Package scanning feature, simply add the wildcard, *, as the last item in the comma-separated list inside the Import-Package element, as shown in the following example:

To install and run the generated cxf-code-first-bundle project, perform the following steps:

  1. Build the project—open a command prompt and change directory to ProjectDir/cxf-code-first-bundle. Use Maven to build the demonstration by entering the following command:

    mvn install

    If this command runs successfully, the ProjectDir/cxf-code-first-bundle/target directory should contain the bundle file, cxf-code-first-bundle-1.0-SNAPSHOT.jar.

  2. Install and start the cxf-code-first-bundle bundle—at the Fuse ESB console, enter the following command:

    karaf@root> osgi:install -s file:ProjectDir/cxf-code-first-bundle/target/cxf-code-first-bundle-1.0-SNAPSHOT.jar

    Where ProjectDir is the directory containing your Maven projects and the -s flag directs the container to start the bundle right away. For example, if your project directory is C:\Projects on a Windows machine, you would enter the following command:

    karaf@root> osgi:install -s file:C:/Projects/cxf-code-first-bundle/target/cxf-code-first-bundle-1.0-SNAPSHOT.jar
    [Note]Note

    On Windows machines, be careful how you format the file URL—for details of the syntax understood by the file URL handler, see File URL Handler.

    Alternatively, you could install the bundle from your local Maven repository, using the following PAX mvn URL:

    karaf@root> osgi:install -s mvn:org.fusesource.example/cxf-code-first-bundle/1.0-SNAPSHOT
  3. Test the Web serivce—to test the Web service deployed in the previous step, you can use a web browser to query the service's WSDL. Open your favorite web browser and navigate to the following URL:

    http://localhost:8181/cxf/PersonServiceCF?wsdl

    When the web service receives the query, ?wsdl, it returns a WSDL description of the running service.

  4. Stop the cxf-code-first-bundle bundle—to stop the cxf-code-first-bundle bundle, you first need to discover the relevant bundle number. To find the bundle number, enter the following console command:

    karaf@root> osgi:list

    At the end of the listing, you should see an entry like the following:

    [ 191] [Active     ] [            ] [       ] [   60] A CXF Code First OSGi Project (1.0.0.SNAPSHOT)

    Where, in this example, the bundle number is 191. To stop this bundle, enter the following console command:

    karaf@root> osgi:stop 191
