| CXF OSGi HTTP WEB SERVICE |
| ========================= |
| |
| Purpose |
| ------- |
| Create a web service with CXF and expose it through the OSGi HTTP |
| Service. |
| |
| |
| Explanation |
| ----------- |
| The web service is a simple JAX-WS web service called HelloWorld. The |
| interface and the implementation are located in the src/main/java/org/ |
| apache/servicemix/examples/cxf directory of this example. |
| |
| The beans.xml file, located in the src/main/resources/META-INF/spring |
| directory: |
| |
| 1. Imports the configuration files needed to enable CXF and OSGi work |
| together. |
| |
| 2. Configures the web service endpoint as follows: |
| |
| <jaxws:endpoint id="helloWorld" |
| implementor="org.apache.servicemix.examples.cxf.HelloWorldImpl" |
| address="/HelloWorld"/> |
| |
| |
| Prerequisites for Running the Example |
| ------------------------------------- |
| 1. You must have the following installed on your machine: |
| |
| - JDK 1.6 or higher |
| |
| - Maven 2.2.1 or higher |
| |
| For more information, see the README in the top-level examples |
| directory. |
| |
| |
| 2. Start ServiceMix by running the following command: |
| |
| <servicemix_home>/bin/servicemix (on UNIX) |
| <servicemix_home>\bin\servicemix (on Windows) |
| |
| |
| Running the Example |
| ------------------- |
| You can run the example in two ways: |
| |
| - A. Using a Prebuilt Deployment Bundle: Quick and Easy |
| This option is useful if you want to see the example up and |
| running as quickly as possible. |
| |
| - B. Building the Example Bundle Yourself |
| This option is useful if you want to change the example in any |
| way. It tells you how to build and deploy the example. This |
| option might be slower than option A because, if you do not |
| already have the required bundles in your local Maven |
| repository, Maven will have to download the bundles it needs. |
| |
| A. Using a Prebuilt Deployment Bundle: Quick and Easy |
| ----------------------------------------------------- |
| To install and run a prebuilt version of this example, enter |
| the following command in the ServiceMix console: |
| |
| feature:install examples-cxf-osgi |
| |
| This command makes use of the ServiceMix features facility. For |
| more information about the features facility, see the README.txt |
| file in the examples parent directory. |
| |
| To view the service WSDL, open your browser and go to the following |
| URL: |
| |
| http://localhost:8181/cxf/HelloWorld?wsdl |
| |
| Note, if you use Safari, right click the window and select |
| 'Show Source'. |
| |
| Running a Client |
| ---------------- |
| To run the web client: |
| |
| 1. Open the client.html, which is located in the same directory as |
| this README file, in your favorite browser. |
| |
| 2. Click the Send button to send a request. |
| |
| Once the request has been successfully sent, a response similar |
| to the following should appear in the right-hand panel of the |
| web page: |
| |
| STATUS: 200 |
| <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> |
| <soap:Body><ns2:sayHiResponse xmlns:ns2="http://cxf.examples. |
| servicemix.apache.org/"><return>Hello John Doe</return> |
| </ns2:sayHiResponse> |
| </soap:Body> |
| </soap:Envelope> |
| |
| To run the java code client: |
| |
| 1. Change to the <servicemix_home>/examples/cxf/cxf-osgi |
| directory. |
| |
| 2. Run the following command: |
| |
| mvn compile exec:java |
| |
| If the client request is successful, a response similar to the |
| following should appear in the ServiceMix console: |
| |
| <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> |
| <soap:Body><ns2:sayHiResponse xmlns:ns2="http://cxf.examples. |
| servicemix.apache.org/"><return>Hello John Doe</return> |
| </ns2:sayHiResponse> |
| </soap:Body> |
| </soap:Envelope> |
| |
| |
| Changing /cxf servlet alias |
| --------------------------- |
| By default CXF Servlet is assigned a '/cxf' alias. You can |
| change it in a couple of ways |
| |
| a. Add org.apache.cxf.osgi.cfg to the /etc directory and set |
| the 'org.apache.cxf.servlet.context' property, for example: |
| |
| org.apache.cxf.servlet.context=/custom |
| |
| b. Use shell config commands, for example : |
| |
| config:edit org.apache.cxf.osgi |
| config:property-set org.apache.cxf.servlet.context /super |
| config:update |
| |
| |
| B. Building the Example Bundle Yourself |
| --------------------------------------- |
| To install and run the example where you build the example bundle |
| yourself, complete the following steps: |
| |
| 1. If you have already run the example using the prebuilt version as |
| described above, you must first uninstall the examples-cxf-osgi |
| feature by entering the following command in the ServiceMix console: |
| |
| feature:uninstall examples-cxf-osgi |
| |
| |
| 2. Build the example by opening a command prompt, changing directory to |
| examples/cxf-osgi (this example) and entering the following Maven |
| command: |
| |
| mvn install |
| |
| If all of the required OSGi bundles are available in your local |
| Maven repository, the example will build very quickly. Otherwise |
| it may take some time for Maven to download everything it needs. |
| |
| The mvn install command builds the example deployment bundle and |
| copies it to your local Maven repository and to the target directory |
| of this example. |
| |
| 3. Install the example by entering the following command in |
| the ServiceMix console: |
| |
| feature:install examples-cxf-osgi |
| |
| It makes use of the ServiceMix features facility. For more |
| information about the features facility, see the README.txt file |
| in the examples parent directory. |
| |
| To view the service WSDL, open your browser and go to the following |
| URL: |
| |
| http://localhost:8181/cxf/HelloWorld?wsdl |
| |
| Note, if you use Safari, right click the window and select |
| 'Show Source'. |
| |
| You can try running a client against your service by following the |
| instructions in the "Running a Client" section above. |
| |
| |
| Stopping and Uninstalling the Example |
| ------------------------------------- |
| To stop the example, you must first know the bundle ID that ServiceMix |
| has assigned to it. To get the bundle ID, enter the following command |
| at the ServiceMix console: |
| |
| bundle:list |
| |
| At the end of the listing, you should see an entry similar to the |
| following: |
| |
| [170] [Active ] [Started] [ 60] Apache ServiceMix Example :: CXF OSGi (4.2.0.0) |
| |
| In this case, the bundle ID is 170. |
| |
| To stop the example, enter the following command at the ServiceMix |
| console: |
| |
| bundle:stop <bundle_id> |
| |
| For example: |
| |
| bundle:stop 170 |
| |
| To uninstall the example, enter one of the following commands in |
| the ServiceMix console: |
| |
| feature:uninstall examples-cxf-osgi |
| |
| or |
| |
| bundle:uninstall <bundle_id> |
| |
| |
| Viewing the Log Entries |
| ----------------------- |
| You can view the entries in the log file in the data/log |
| directory of your ServiceMix installation, or by typing |
| the following command in the ServiceMix console: |
| |
| log:display |
