What is cxf used for

The greetings method receives a parameter of string type, appends it to a greeting message and returns the resultant string to the caller. We set the URL for calling our service by calling the factory's setAddress method. Note that the service will be published at this URL. In this case, the service is deployed on the embedded server and will be listening to port You may opt for any port number of your choice. Before creating the factory, you need to tell the factory about our service implementation class.

The service bean is set to the instance of our service implementation class. Now, as we have developed the factory to run our web service, we will next write a main method to instantiate it and keep it running for some time. Once instantiated, the HelloServer class will keep running indefinitely. For production deployments, you will definitely keep your server running forever. We must now include these libraries in our project to successfully compile the HelloServer class. We will use Maven to set up the project dependencies.

To create a Maven project, type the following command in your command-line window. Note that we have tested this on a Mac machine. For Windows and Linux installations, the instructions may differ at few places. On the completion of the maven command, you will find the appropriate folder structure created in your current folder along with pom.

You will add the CXF dependencies in the pom. For your ready reference, we have given below the pom. The above pom. Anyway, there is no harm as such in including additional dependencies.

Now, in your browser window specify the URL of our published service. This confirms that our service is running at the specified port on a localhost. Since we did not specify the greetings message in our call, a SOAP fault message is returned to the browser. You may further test your web service using a SOAP client of your choice. Here we have used Postman to test our server. After posting the request, the server sent a SOAP Response message, which is seen in the bottom portion of the screen shot.

From this, you can understand that CXF maintains the use of SOAP protocols for both request and response while providing you a unified view to a variety of web technologies that do exist in today's world.

This greatly simplifies the web application development. In the server application HelloWorld is the interface that exposes our web service. The web service itself just provides a plain greeting message to the client.

In this trivial application, we will expose our web service to the client by exposing directly the service interface and that is the HelloWorld. For this purpose, CXF provides a factory class called ClientProxyFactoryBean that allows us to attach to the desired interface to the created factory instance. We call the setAddress method on the factory bean instance to set the URL by which our web service can be invoked. Next, we call the create method on the factory instance to attach our service interface HelloWorld.

Make sure that the server is still running on your machine. So first we will create an interface for our web service. As in the earlier case, we will create a trivial service that has only one interface method called greetings. The greetings method is annotated with Override tag.

The method returns a "hi" message to the caller. The first parameter of the publish method specifies the URL at which our service will be made available to the clients. The second parameter specifies the implementation class for our service. To deploy our server, you will need to make few more modifications to your project as listed below.

Finally, to deploy the server application, you will need to make one more modification in pom. The code that you need to add into your pom. Before you deploy the application, you need to add two more files to your project.

The code within the web. In the cxf-servlet. Here we define the id for our service endpoint, the address on which the service will be available, the service name and the endpoint name. Now, you learnt how your service gets routed and processed by a CXF servlet.

The pom. Rather than describing all the dependencies, we have included the final version of pom. Note that it also includes a profile for building client that we will be learning in the later sections of this tutorial. Now, you are ready to run the web app. In the command window, run the build script using the following command. As we did not specify any operation, only a fault message is returned to the browser by our application. So our server application is running as expected.

Writing the client in a CXF application is as trivial as writing a server. What is Cxf bus? The Bus is the backbone of the CXF architecture. It manages extensions and acts as an interceptor provider. Note: For endpoint-specific configuration as opposed to configuration for all for endpoints created by the CXF bus , look at the Logging Messages section for code samples.

What is Camel CXF? CXF Component. The bean component's configuration is also simpler and provides the fastest method to implement web services using Camel and CXF. What is Apache CXF tutorial? It is part of the Apache Software Foundation. A decentralized open source community of developers. How do I open a. CXF file? For Eclipse users, you should read about Setting up Eclipse. Apache CXF. Downloads are available here. June 8, - Apache CXF 3. March 22, - Apache CXF 3. Frontends: CXF supports a variety of "frontend" programming models.

Ease of use: CXF is designed to be intuitive and easy to use.
