登陆窗口怎么做(50分)

jerjoan · 2003-10-07

我是java初学者,想用java做一个登陆窗口,在界面上输入用户名和密码后,可以按"确定"按钮进行用户名密码较验,如果正确则进入下一界面,如果不正确则会弹出一个提示框,也可以按"退出"铵钮退出登陆界面.(特别是如何弹出提示框和如何实现按下"退出"按钮后退出)
我用的是sdk + Tomcat,问题虽浅,还望诸位指点.

javascript实现，与java无关。
<input type=button value="提示" onclick=alert("test") >
<input type=button value="关闭本页面" onclick=window.close() >

能不能告诉一下,是用java写终端,还是使用jsp写页面啊,实现方式不一样啊.
用java的话就new一个对话框好了.然后用事件监控.
如果用jsp就是像楼上说的,用script就好了,但是,应该是在jsp里面嵌script,因为你还是要校验用户名和口令啊,就直接使用out.println向页面输出script代码就好了.

我是想用jsp页面，就算用javaScript写，可是我不知道具体怎么实现在jsp中嵌入javaScript,小生愚钝，望明示。
