Apache CXF with JMS JAX-WS Example-IGI

www.igi‮oc.aeditf‬m

here's an example of how to use Apache CXF to create a JMS service using JAX-WS.

First, we need to add the CXF dependencies to our project. We can do this by adding the following dependencies to our Maven pom.xml file:

<dependencies>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>3.4.5</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-jms</artifactId>
        <version>3.4.5</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-bindings-xml</artifactId>
        <version>3.4.5</version>
    </dependency>
</dependencies>

Next, we can create a service interface that will define our JMS service. Let's create an interface called "HelloService" that will have a single method called "sayHello" that takes a String parameter and returns a String:

package com.example;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface HelloService {

    @WebMethod
    String sayHello(String name);

}

We can then create an implementation of this interface. Let's create a class called "HelloServiceImpl" that implements the "HelloService" interface:

package com.example;

@WebService(endpointInterface = "com.example.HelloService")
public class HelloServiceImpl implements HelloService {

    public String sayHello(String name) {
        return "Hello " + name;
    }

}

Finally, we need to configure the JMS transport for our service. We can do this by creating a file called "cxf.xml" in the "src/main/resources/META-INF" directory. Here's what the file should look like:

<bus>
    <jaxws:server serviceClass="com.example.HelloService"
        address="jms://queue:HelloQueue">
        <jaxws:serviceFactory>
            <ref bean="cxf"/>
        </jaxws:serviceFactory>
        <jaxws:features>
            <bean class="org.apache.cxf.feature.LoggingFeature"/>
        </jaxws:features>
        <jaxws:endpoint>
            <cxf:properties>
                <entry key="dataFormat" value="PAYLOAD"/>
                <entry key="transport.jms.ConnectionFactory" value="ConnectionFactory"/>
            </cxf:properties>
        </jaxws:endpoint>
    </jaxws:server>
</bus>

In this file, we're configuring a JAX-WS server that will listen for messages on the "HelloQueue" JMS queue. We're also setting the data format to "PAYLOAD" and specifying the JMS connection factory to use.

We can now create a main method that will start up our JMS service. Here's what the main method should look like:

import org.apache.cxf.Bus;
import org.apache.cxf.BusFactory;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class HelloServicePublisher {

    public static void main(String[] args) {
        // Create the CXF bus
        Bus bus = BusFactory.getDefaultBus();

        // Create the JAX-WS server
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
        factory.setBus(bus);
        factory.setServiceBean(new
