本文介绍如何在Web应用中通过web.xml配置文件使用HessianServlet来实现Java服务类之间的远程调用，包括服务类的创建、配置及客户端调用过程。

web.xml:

<servlet-name>testService</servlet-name>

<servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class>

<init-param>

<param-name>home-api</param-name>

<param-value>com.caucho.hessian.test.TestService</param-value>

</init-param>

<init-param>

<param-name>home-class</param-name>

<param-value>com.caucho.hessian.test.TestServiceImpl</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>testService</servlet-name>

<url-pattern>/testService</url-pattern>

</servlet-mapping>

java服务类：

public class TestServiceImpl implements TestService{
	public String say(){
		return "test:" + TestServiceImpl.class.getName();
	}
	
	public TestObject getTestObject(){
		return new TestObject("123456");
	}
}

public interface TestService {
	String say();
	
	TestObject getTestObject();
}

public class TestObject {
  private Object _value;

客户端：

public class Main {
	public static void main(String[] arg) throws Exception{
		String urlString = "http://localhost/hessian/testService";
		HessianProxyFactory factory = new HessianProxyFactory();
		TestService testService = (TestService)factory.create(TestService.class,urlString);
		System.out.println(testService.say());
		System.out.println(testService.getTestObject());
	}
}
