Jsp 调用EJB3问题
小弟，学习ejb3 写了个Hello Bean，用客户端方式调用没有问题，可是用jsp去调用就报异常，不知是什么问题。环境:
Jboss 5.1
myecplise 7.0
hello接口
public interface HelloEjbInterface {
public String sayHello(String message);
}
helloBean
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
@Remote
public class HelloejbBean implements HelloEjbInterface {
public String sayHello(String message) {
return "你好!"+message;
}
}
hello.jsp页面
<%@page contentType="text/html; charset=GBK"%>
<%@page import="com.ejb.*,javax.naming.*"%>
<%
try {
InitialContext context = new InitialContext();
HelloEjbInterface hello = (HelloEjbInterface) context
.lookup("HelloejbBean/remote");
String h = hello.sayHello("Hello world!");
out.println(h);
} catch (NamingException ne) {
ne.printStackTrace();
}
%>

--------------------编程问答-------------------- 解决了没有，我想知道答案！ --------------------编程问答-------------------- 我的也一样啊~有没有人能解决啊？ --------------------编程问答-------------------- 我感觉是在jboss启动的时候就报错了，楼主可以试下访问jboss控制页面，1看是否jboss正常启动，2如果jboss正常启动，看管理页面ejb是否部署成功 --------------------编程问答-------------------- 你那jndi.proporties 是怎么写的 ？
你要LOOKUP 起码 context 要对啊。
补充：Java , Web 开发
