Explanation ----------- This example consists of: 1. An endpoint bundle that includes: - An EchoEndpoint Java class that adds an "Echo" prefix to any messages it receives from the client and returns the updated messages. The EchoEndpoint.java file is located in the endpoint/src/main/java/org/apache/ servicemix/nmr/examples/nmr/endpoint directory of this example. - A Spring configuration file, beans.xml, which makes the EchoEndpoint functionality available as a service. The beans.xml file is located in the endpoint/src/main/ resources/META-INF/spring directory of this example. 2. A client bundle that includes: - A Client Java class that accesses the NMR and sends messages to the EchoEndpoint service. The Client.java file is located in the client/src/main/java/org/apache/ servicemix/nmr/examples/nmr/client directory of this example. - A Spring configuration file, beans.xml, which configures the client and the NMR. The beans.xml file is located in the client/src/main/resources/META-INF/spring directory of this example. Prerequisites for Building and 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 building) For more information, see the README in the top-level examples directory. 2. Start ServiceMix by running the following command: /bin/servicemix (on UNIX) \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 quickly. - 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-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. You can verify that example is running by looking at the log file in the data/log directory of your ServiceMix installation, or by typing the following command in the ServiceMix console: log:display You should see output similar to following appearing in the log file every five seconds: 09:35:02,450 | INFO | ndpoint-thread-1 | EchoEndpoint | amples.nmr.endpoint.EchoEndpoint 34 | Received in EchoEndpoint: Hello 09:35:02,451 | INFO | Thread-8 | Client | x.nmr.examples.nmr.client.Client 75 | Response from Endpoint EchoHello 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-nmr feature by entering the following command in the ServiceMix console: features:uninstall examples-nmr 2. Build the example by opening a command prompt, changing directory to examples/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 quickly. Otherwise it may take some time for Maven to download everything it needs. The mvn install command builds the example deployment bundles and copies them to your local Maven repository and to the target subdirectory of the example client and endpoint directories. 3. Install the example by entering the following command in the ServiceMix console: features:install examples-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. You can verify that example is running by looking at the log file in the data/log directory of your ServiceMix installation, or by typing the following command in the ServiceMix console: log:display You should see output similar to following appearing in the log file every five seconds: 09:35:02,450 | INFO | ndpoint-thread-1 | EchoEndpoint | amples.nmr.endpoint.EchoEndpoint 34 | Received in EchoEndpoint: Hello 09:35:02,451 | INFO | Thread-8 | Client | x.nmr.examples.nmr.client.Client 75 | Response from Endpoint EchoHello 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: osgi:list At the end of the listing, you should see an entry similar to the following: [ 168] [Active ] [ ] [Started ] [ 60] Apache ServiceMix NMR Example:: NMR Endpoint (1.1.0.2) [ 169] [Active ] [ ] [Started ] [ 60] Apache ServiceMix NMR Example:: NMR Client (1.1.0.2) In this case, the bundle IDs are 168 and 169. To stop the example, enter the following command at the ServiceMix console: osgi:stop To uninstall the example, enter one of the following commands in the ServiceMix console: features:uninstall examples-nmr or osgi:uninstall
