| CXF, CAMEL and NMR EXAMPLE |
| ========================== |
| |
| Purpose |
| ------- |
| Create a Camel route that transforms a message, then passes it to a |
| CXF web service via the NMR. |
| |
| |
| Explanation |
| ----------- |
| The Camel route is defined in the beans.xml file that is located |
| in the src/main/resources/META-INF/spring directory of this example. |
| |
| The route is defined in the <route> element and can be explained |
| as follows: |
| |
| 1. A message flow is triggered every five seconds. |
| |
| 2. It is sent to the MyTransform bean, which adds a SOAP message. |
| |
| 3. It is sent via the NMR to the HelloWorld web service. |
| |
| 4. Responses are routed to the display method of the MyTransform |
| class. |
| |
| The web service is defined as follows: |
| |
| <jaxws:endpoint id="helloWorld" |
| implementor="org.apache.servicemix.examples.cxfcamel.HelloWorldImpl" |
| address="nmr:HelloWorld" /> |
| |
| |
| Prerequisites for Running the Example |
| ------------------------------------- |
| 1. You must have the following installed on your machine: |
| |
| - JDK 1.5 or higher |
| |
| - Maven 2.0.9 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: |
| |
| features:install examples-cxf-camel-nmr |
| |
| 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. |
| |
| Once the example is running, periodic SOAP messages are displayed by |
| the transform method of the MyTransform class. These messages are routed |
| to the CXF endpoint, and the responses are routed to the display method |
| of the MyTransform class. You should see output similar to the following |
| being logged to your console screen: |
| |
| >>>> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> |
| <soap:Body><ns1:sayHi xmlns:ns1="http://cxf.examples.servicemix.apache.org/ |
| "><arg0>Guillaume</arg0></ns1:sayHi></soap:Body></soap:Envelope> |
| <<<< <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> |
| <soap:Body><ns2:sayHiResponse xmlns:ns2="http://cxfcamel.examples. |
| servicemix.apache.org/"><return>Hello Guillaume</return> |
| </ns2:sayHiResponse></soap:Body></soap:Envelope> |
| |
| For information on how to stop and/or uninstall the example, |
| see "Stopping and Uninstalling the Example" below. |
| |
| |
| 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-camel-nmr |
| feature by entering the following command in the ServiceMix console: |
| |
| features:uninstall examples-cxf-camel-nmr |
| |
| 2. Build the example by opening a command prompt, changing directory to |
| examples/cxf-camel-nmr (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: |
| |
| features:install examples-cxf-camel-nmr |
| |
| 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. |
| |
| Once the example is running, periodic SOAP messages are displayed by |
| the transform method of the MyTransform class. These messages are routed |
| to the CXF endpoint, and the responses are routed to the display method |
| of the MyTransform class. You should see the messages displayed on your |
| console. |
| |
| |
| 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 |
| in the ServiceMix console (Note, the text you are typing will intermingle |
| with the output being logged. This is nothing to worry about.): |
| |
| osgi:list |
| |
| At the end of the listing, you should see an entry similar to the |
| following: |
| |
| [165] [Active ] [Started] [ 60] Apache ServiceMix Example :: CXF-Camel NMR (4.1.0) |
| |
| In this case, the bundle ID is 165. |
| |
| To stop the example, enter the following command in the ServiceMix |
| console: |
| |
| osgi:stop <bundle_id> |
| |
| For example: |
| |
| osgi:stop 165 |
| |
| To uninstall the example, enter one of the following commands in |
| the ServiceMix console: |
| |
| features:uninstall examples-cxf-camel-nmr |
| |
| or |
| |
| osgi: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 |
