如何将hibernate与jsp接口集成 [英] How to integrate hibernate with jsp interface

问题描述

< big>这里是我的jsp页面代码，在这个页面中我尝试调用我在Users包中定义的signUp.java，我在src FileFolder中测试了这个类，这意味着它可以在没有任何问题的情况下在java应用程序上运行< / big> 
< pre><％@ page language =javaimport =Users。*，Hibernate。*contentType =text / html; charset = GB18030pageEncoding =GB18030％>

我尝试了什么：



i已将所有需要的软件包放入WEBINF / lib中，但是它仍然不起作用

解决方案

<big>here is my jsp Page code,in this page i try to call signUp.java which i  have defined in Users package,and i have test this class in src FileFolder so that means it can run on java application without any problems </big>
<pre><%@ page language="java" import="Users.*,Hibernate.*" contentType="text/html; charset=GB18030"  pageEncoding="GB18030"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB18030">
<title>SignUp_Page</title>
</head>
<body>
<jsp:useBean id="sup" class="Users.signUp"/>
<form action="userlogin.jsp" method="post">
	<table align="center">
		<tr>
			<th>user_id</th><td><input type="text" name=uid></td>
		</tr>
		<tr>
			<th>user_name</th><td><input type="text" name="uname"></td>
		</tr>
		<tr>
			<th>user_pwd</th><td><input type="text" name="upwd"></td>

		<tr>
			<td><input type="submit" value="Sign up!"></td>

	</table>

</form>

	<%	
		String uid=request.getParameter("uid");
		String uname=request.getParameter("uname");
		String upwd=request.getParameter("upwd");

		sup.addUser(uid,uname,upwd);
	%>
</body>
</html>

//and when i run this jspPage,here is the Error:

What I have tried:

i have put all the needed package in WEBINF/lib,but it still not work

解决方案

AbstractConnectionHandler.process(AbstractProtocol.java:637) at org.apache.tomcat.util.net.JIoEndpoint

SocketProcessor.run(JIoEndpoint.java:316) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor

Worker.run(Unknown Source) at org.apache.tomcat.util.threads.TaskThread
