Today I will show you how you can create a webservice using Apache CXF version 2.2.1. I will be building this webservice on top of my
previous application.
Create a interface AirlineManager to expose methods over webservice. The create method takes airline code and name to create a Airline record in database. Annotation @WebService tells that this is a interface for webservice.
package com.travel;
import javax.jws.WebService;
@WebService
public interface AirlineManager {
public void create(String code, String name);
}
Implement the above webservice interface. We are using AirlineDao created in earlier post. Notice the @WebService(endpointInterface = "com.travel.AirlineManager") which tells that this implementation is for AirlineManager interface.
package com.travel;
import com.travel.dao.AirlineDao;
import javax.jws.WebService;
@WebService(endpointInterface = "com.travel.AirlineManager")
public class AirlineManagerImpl implements AirlineManager {
private AirlineDao airlineDao;
public AirlineManagerImpl(AirlineDao aAirlineDao) {
airlineDao = aAirlineDao;
}
@Override
public void create(String code, String name) {
airlineDao.create(code, name);
}
}
Add this in the spring-context.xml. Here we are importing some cxf beans, defining bean AirlineManagerImpl and creating airlineManagerService webservice.
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-http-jetty.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<bean id="airlineManager" class="com.kaleconsultants.travel.AirlineManagerImpl">
<constructor-arg><ref bean="airlineDao"/></constructor-arg>
</bean>
<jaxws:endpoint id="airlineManagerService" implementor="#airlineManager" address="/AirlineManagerService" />
Add this in your web.xml.
<servlet>
<servlet-name>CXFServlet</servlet-name>
<display-name>CXF Servlet</display-name>
<servlet-class>
org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
Deploy the application in tomcat and your webservice is ready. You can check the wsdl http://host:port/travel/AirlineManagerService?wsdl.
To test the webservice, you need to create a client. You can use wsdl2java available in the bin directory of cxf.
Execute this command, this will generate the wsdl stubs.
wsdl2java http://host:port/travel/AirlineManagerService?wsdl
Write a client like this and there you go.......
package com.travel;
public class ClientTest {
public static void main(String[] args) {
AirlineManagerImplService service = new AirlineManagerImplService();
AirlineManager airlineManager = service.getAirlineManagerImplPort();
airlineManager.create("IC", "Indian");
}
}
