Example Java code of a User service

package org.foo.user.service;
public class UserService {
	/**
	 * Create a new User
	 */
	public void create (User user, ResoaResponse response, ResoaGateway gateway) {
		// Add your business logic here. 
	}
	/**
	 * Handle a login request 
	 */
	public void login (User user, ResoaResponse response, ResoaGateway gateway) {
		// Add your business logic here.	
	}
	/**
	 * Log out an user
	 */
	public void logout (User user, ResoaResponse response, ResoaGateway gateway) {
		// Add your business logic here.
	}
}

Characteristics of Resoa Services

A single service is class method with dedicated parameters.
Services are linked to types, which are designed by XSD (here the User class as first parameter in each method). The service implementation for a business object is done within one class.
There is only one naming convention, the service implementation class name must extend the underlying XSD defined type name by Service (here the UserService class).
