急急急: 帮帮忙: jsp 调用webservice 出现问题(一个登录程序)

[newfireflying]

webservice 服务端 主要代码:

public boolean login( String username , String password )
{
/*
数据库连接部分代码
*/

成功登录返回true;
}

单独以 java应用程序的形式运行服务器端,如输入: 用户名:"tomcat",密码:"123456"
输出:登录成功.

将服务端发布生成wsdl文件,以便生成客户端代理.

webservice 客户端

view.jsp 主要代码:

<form name="form1" method="post" action="loginProcess.jsp">
<label>用户名</label> <input type="text" name="username"> <a href="" target="_blank"></a>
<br>
<label>密 码 </label> <input type="Password" name="password">
<br>
<br>
<input type="submit" name="ok" value="登录">
<input type="submit" name="cancel" value="取消" >

loginProcess.jsp主要代码:

<jsp:useBean id="user" class="bank.UserInfoProxy" scope="session"></jsp:useBean>
<%
String username = request.getParameter("username");
String password = request.getParameter("password");
out.print(username);
out.print(password);
if( user.login(username,password)==true )
out.print("登陆成功");
else
out.print("登录失败");
%>

运行view.jsp 输入"tomcat" "123456" 出现登录失败?
大家帮忙下,这是为什么呀?

<input type="submit" name="ok" value="登录">
<input type="submit" name="cancel" value="取消" >
这个地方value值好像不能用汉字吧。应该是你的描述吧？

你这个思路是没有问题的，我按你的思路调试了一下，没有任何问题，输出登陆成功。你没有列出详细代码，估计是有地方写错了吧。
既然出现登录失败，说明user.login(username,password)返回值为false，
你在login方法里面输出一下这两个参数得值，看看就明白了

服务端代码:

public boolean login(String name,String password)
{
if( connectDB()==true) //connectDB()是数据库连接函数.
{
sqlStatement = "select * from userInfo where userName= ? and userPassword= ? ";
try {
ps = con.prepareStatement(sqlStatement);
ps.setString(1,name);
ps.setString(2,password);
rs = ps.executeQuery();
rs.last();
rowCount = rs.getRow();
if (rowCount ==1)
{
rs.close();
ps.close();
con.close();
return true;
}
else
{
System.out.println("用户名或密码错误");
return false;
}
} catch (Exception e) {
e.printStackTrace();
return false;
}

}
else
return false;

}

测试服务端: public static void main(String[] args)
{
UserInfo ui = new UserInfo();
if ( true==ui.login("jerry","654321") )
System.out.println("success");

}
结果显示: success

客户端代码:

view.jsp 主要代码:

<form name="form1" method="post" action="loginProcess.jsp">
<label>用户名 </label> <input type="text" name="username"> <a href="" target="_blank"> </a>
<br>
<label>密 码 </label> <input type="Password" name="password">
<br>
<br>
<input type="submit" name="ok" value="登录">
<input type="submit" name="cancel" value="取消" >

loginProcess.jsp主要代码:

<jsp:useBean id="user" class="bank.UserInfoProxy" scope="session"> </jsp:useBean>
<%
String username = request.getParameter("username");
String password = request.getParameter("password");
out.print(username);
out.print(password);
if( user.login(username,password)==true )
out.print("登陆成功");
else
out.print("登录失败");
%>

运行后:
输入: jerry
654321

结果显示:jerry654321登录失败.

ps:是不是我哪里没设置好呀? 难道是我电脑有问题? 我都快郁闷的崩溃了,大家帮忙想下,谢谢了.

我经过调试后发现:
服务器端单独运行,没有任何错误,数据库连接正常的.
在发布后,运行客户端时,有异常信息: Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.

居然说没找到驱动,很不明白.我在工程中已经加入了 驱动呀.
是不是还要配置下tomcat呀.
