The simplest Hessian code example of a binary Web service framework

Passed the resin3.1 Test

Hessian version: hessian-3.1.6.jar

Official Address:

Http://hessian.caucho.com/#Java

Http://hessian.caucho.com/

The procedure is as follows:

1. Interface Definition

Package com. yanek. study. hessian;

Public interface Hello {
 
Public String hello (String name );

}

 

2. Interface implementation

Package com. yanek. study. hessian;

Public class HelloImpl implements Hello {

Public String hello (String name)
{

Return "hello" + name + "welcome study Hessian ";

}

}

 

3. web. xml configuration

Configure HessianServlet and configure the class that provides the service

<Servlet>

<Servlet-name> hessianService </servlet-name>

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

<Load-on-startup> 1 </load-on-startup>

 

<Init-param>

<Param-name> service-class </param-name>

<Param-value> com. yanek. study. hessian. HelloImpl </param-value>

</Init-param>

</Servlet>

<Servlet-mapping>
<Servlet-Name> hessianservice </servlet-Name>
<URL-pattern>/hessianservice </url-pattern>

</Servlet-mapping>

 

4. Client test class:

Package com. Yanek. Study. Hessian;

Import java.net. malformedurlexception;

Import com. Caucho. Hessian. Client. hessianproxyfactory;

Public class hessianclient {

/**
* @ Param ARGs
*/
Public static void main (String [] args ){

// Hessian service url

String url = "http://study.myweb.com/hessianService ";

// Create a HessianProxyFactory instance

HessianProxyFactory factory = new HessianProxyFactory ();

// Obtain the remote reference of the Hessian Service

Hello d;
Try {
D = (Hello) factory. create (Hello. class, url );
// Call the remote service.

System. out. println ("the Hessian service is called below:" + d. hello ("yanek "));
} Catch (MalformedURLException e ){
// TODO Auto-generated catch block
E. printStackTrace ();
}
