JBoss下的EJB3开辟无情况会话Bean[Java编程]

1.开辟一个具有Remote和Local接口的EJB3 Stateless SessionBean.
若有那边写的不好请大家多多指教.

Remote接口:RemoteHelloWorld.java
Local接口:LocalHelloWorld.java
SessionBean:HelloWorldBean.java
JNDI配置:jndi.properites
JSP:hello.jsp package com.yourcompany.ejb3;
public interface RemoteHelloWorld{
public String Say(String name);
}

package com.yourcompany.ejb3;
public interface LocalHelloWorld{
public String Say(String name);
}

package com.yourcompany.ejb3;
import javax.ejb.Stateless;
import javax.ejb.Remote;
import javax.ejb.Local;
import com.yourcompany.ejb3.RemoteHelloWorld;
import com.yourcompany.ejb3.LocalHelloWorld;

@Remote({RemoteHelloWorld.class})
//注释表示RemoteHelloWorld为这个SessionBean的Remote接口
@Local({RemoteHelloWorld.class})
//注释表示LocalHelloWorld为这个SessionBean的Local接口

//@Stateless注释表示这是一个无状况会话Bean
public @Stateless class HelloWorldBean implements RemoteHelloWorld,LocalHelloWorld{
public String Say(String name){
return "这是一个无状况的EJB3会话BEAN,作者:"+name;
}
}
//JNDI配置奉告了你的客户端初始化jndi naming service
jndi.properties:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

JSP中调用代码以下:
<%
Properties prop=new Properties();
prop.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("jndi.properties"));
InitialContext ctx=new InitialContext(prop);
RemoteHelloWorld remotehelloworld=(RemoteHelloWorld)ctx.lookup("HelloWorldBean/remote");
remotehelloworld.Say("Christina007[remote]");
LocalHelloWorld localhelloworld=(LocalHelloWorld)ctx.lookup("HelloWorldBean/local");
localhelloworld.Say("Christina007[local]");
%>

运行后果:
这是一个无状况的EJB3会话BEAN,作者:Christina007[remote]

这是一个无状况的EJB3会话BEAN,作者:Christina007[local]

总结步骤:
1.先写好了SessionBean的业务逻辑接口
2.再写SessionBean,记得在SessionBean实现了业务逻辑接口
