Example of SOAP RPC Web Service in Java
In this article, we will show how to create a simple RPC web service example in java using SOAP and associated with its client in a servlet container. This example is used further in Secure Web Service with Basic Authentication and Secure SOAP Web Service over SSL.
1. Create a Web Service Endpoint Interface
Let's start with creating SEI with two methods:
package example;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface ExamClouds {
@WebMethod
String getSiteName();
@WebMethod
String getSiteDescription();
}
2. Create a Web Service Endpoint Implementation
package example;
import javax.jws.WebService;
@WebService(endpointInterface = "example.ExamClouds")
public class ExamCloudsImpl implements ExamClouds {
public String getSiteName() {
return "http://www.examclouds.com";
}
public String getSiteDescription() {
return "Java Tutorial";
}
}
3. Create web.xml
<servlet>
<servlet-name>ExamClouds</servlet-name>
<servlet-class>example.ExamCloudsImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ExamClouds</servlet-name>
<url-pattern>/ExamClouds</url-pattern>
</servlet-mapping>
4. Deploy Web Service
Compile and package the web service into a WAR file, and deploy it into a Java EE servlet container.
5. Test a Web Service
The deployed web service can be tested by accessing the generated WSDL document via the URL “http://<YOUR_HOST>/ws1-1.0-SNAPSHOT/ExamClouds?wsdl”.
6. Create a Web Service Client
The wsimport tool helps with creating soap web service client example in java:
wsimport -s src/main/java -p example.client -keep
http://<YOUR_HOST>/ws1-1.0-SNAPSHOT/ExamClouds?wsdl
7. Run the Client
And finally, let's call the web service:
ExamCloudsImplService service = new ExamCloudsImplService();
ExamClouds port = service.getExamCloudsImplPort();
System.out.println(port.getSiteName());
System.out.println(port.getSiteDescription());
