For running this example, below mentioned particulars are used.
In this example, We have an interface HelloWS which contains a abstract method sayHello() which is to be exposed and a class HelloWSImpl.java which will implement HelloWS. Please go through each of the screen shots.
web.xml file is used to defines WSServletContextListener
Path : ${Tomcat}/webapps/SimpleWebservice/WEB-INF/web.xml
sun-jaxws.xml file is used to defines web service implementation class
Path : ${Tomcat}/webapps/SimpleWebservice/WEB-INF/sun-jaxws.xml
If JAXB is not bundled with your tomcat you have to add below mentioned JAR files in ${Tomcat}/lib.
Download JAR file from https://jax-ws.java.net/
Now deploy your web service project to tomcat and hit below mentioned URL, you should able to see below screen shot.
http://localhost:8080/SimpleWebservice/hellows
WSDL Url
http://localhost:8080/SimpleWebservice/hellows?wsdl
Below is the generated XML.
