Answer 1

EJB的东西你把它放到jsp里？？？

Answer 2

我是按书上写的   我是个新手  <%@page contentType="text/html; charset=GBK"%>
<%@page import="ejb.FangFaBeanRemote, javax.naming.*, java.util.Properties,java.util.*"%>
<%
Properties props=new Properties();
props.setProperty("javaq.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.provider.url","localhost:1099");
props.setProperty("java.naming.factory.url.pkgs","org.jboss.naming");
InitialContext ctx;
ctx=new InitialContext(props);
  FangFaBeanRemote fangfa=(FangFaBeanRemote)ctx.lookup("FangFaBean/remote");
  fangfa.insertStudent("ck",true,new Integer(20).shortValue(),"sdfdefd","15555555555","共青团员",4440110,new Integer(3).shortValue(),"经济管理学院","经济管理",new Integer(1).shortValue());
这是jsp的代码
