Hession可以非常方便完成基于Http协议的远程调用，以下是一个非常简单的示例代码，其中Server使用java实现而Client分别使用java和C#实现
(如果您使用vs2003而HessianCSharp需要vs2005，你可以直接引入代码，将不能编译的语句注释掉，然后运行示例－－可以执行。)

Server:
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <!--Definition of View Resolver -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>


    <!--Request Mapping -->
    <bean id="urlMapping"
        class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
    </bean>

    <bean id="helloService" class="cj.domain.HelloService"></bean>

    <bean name="/hello.do" class="org.springframework.remoting.caucho.HessianServiceExporter">
        <property name="service">
            <ref bean="helloService" />
        </property>
        <property name="serviceInterface">
            <value>cj.domain.Hello</value>
        </property>
    </bean>

</beans>

Hello.java
    package cj.domain;

    public interface Hello {
   
        public String hello(String name);
   
    }
   
HelloService.java
    package cj.domain;
    public class HelloService implements Hello {
   
         public String hello(String name){
             return "hello "+name+"!";
         }
   
    }

Java Client:
clientContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <bean id="helloService"    class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
        <property name="serviceUrl">
            <value>
                http://localhost:8080/C3Java/hello.do
            </value>
        </property>
        <property name="serviceInterface">
            <value>cj.domain.Hello</value>
        </property>
    </bean>
</beans>

Client.java
package cj.client;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cj.domain.Hello;
 
public class Client   {

    public static void main(String[] args) {
         String[] paths = { "/cj/client/clientContext.xml" };
         ApplicationContext ctx = new ClassPathXmlApplicationContext(paths);
         Hello hello=(Hello) ctx.getBean("helloService");;
         System.out.println(hello.hello("frank"));
    }

}

C# Client:
    using System;
    using hessiancsharp.client;
    using System.Reflection;
    ....
    ...
    ..
    .
    static void Main(string[] args)
    {
        CHessianProxyFactory chpf=new CHessianProxyFactory();
        Hello hello=(Hello)  chpf.Create(Type.GetType("C3JavaC3Client.Hello"),"http://localhost:8080/C3Java/hello.do");
        System.Console.Out.WriteLine("Call Hello:" +hello.hello("中文"));
    }
