Create a new session bean - the code is formated like:
@Stateless()
public class NewSessionBean implements sdf.NewSessionLocal {
    
}

Create new WS, the code is formated like:
@WebService
        public class Calculator {
    
    /**
     * @param param
     * @return string value
     */
    @WebMethod
            public String operation(String param) {

This is bcs you do not have () after annotations.
I know this is a workaround for a javacore issue, but the issues is not going
away so you better use the workaround.
