关于EJB
最近在做一个小项目 为了体现远程和本地调用还有servlet
要用到jsp、servlet、会话bean、实体bean
他们之间的调用我的想法是jsp提交给servlet
然后调用会话bean ,会话bean是调用实体bean的
运行jsp 
现在做了但是运行jsp怎么都不对
想请教能有一个相似的简单的例子吗
 还有运行jsp是不是:http://localhost:7001/webModule/jsp1.jsp
这个运行有错吗
给分只能是10分 因为自己是新手 而且分数有限 对不起了
谢谢各位了!!
在线等待


------解决方案--------------------
我也刚开始学这个...
我用JBOSS 而且设置端口为8008 然后写了个Converter的小程序...
然后就是在IE输入如下:
http://localhost:8008/ConverterWar/index.jsp
由于自己也是新手...
只能回答这么多了..
------解决方案--------------------
你的配置文件出现问题的可能性最大。。你好好查一下。。。

是400错还是404错?
404的话就是文件不存在的错误
看你样子不用EJB,就不会出问题的情况来看,是EJB引用这里出了点问题
附上jsp调用EJB的代码,希望对你有所帮助:
HTML code

<%@ page contentType="text/html; charset=GBK"%>
<%@ page import="com.foshanshop.ejb3.HelloWorld, javax.naming.*, java.util.Properties"%>
<%
        Properties props = new Properties();
        props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
        props.setProperty("java.naming.provider.url", "localhost:8080");
        props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");    

        InitialContext ctx;
        try {
            ctx = new InitialContext(props);
            HelloWorld helloworld = (HelloWorld) ctx.lookup("HelloWorldBean/remote");
            out.println(helloworld.SayHello("xxx"));
