Java EE (Java Enterprise Edition) General Discussion

I am trying to use ant to use java2wsdl.

Here is my ant code

<?xml version="1.0" standalone="yes"?>
<project basedir="." default="run">

	<path id="axis.classpath">
	  <fileset dir="../lib">
	    <include name="**/*.jar" />
	  </fileset>
	</path>

	<taskdef resource="axis-tasks.properties" classpathref="axis.classpath" />

	<target name="run">		
		<axis-java2wsdl 
			output="out/arash.wsdl"
			location="http://localhost:8080/axis/service/RankingService"
			namespace="service"
			classname="Register">		
			<mapping namespace="register" package="register"/>
		</axis-java2wsdl>
	</target>
	

</project>

here is my file structure

--prj
   |__ lib
   |__ src
   |   |_ build.xml
   |   |_ Register.java

and here is my java code

public class Register {
    private String username;
    private String password;
    
    public void register(String username, String password) {
        
    }
}

I get the following exception

What am I doing wrong? It does not make any sense!
