9 个解决方案
#1
1、在web.xml中设置。在JB中有向导可以设置很方便的。
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.jsp</form-error-page>
</form-login-config>
</login-config>
2、你的form有特别格式。
<form method=”POST” action=”j_security_check”>
<input type=”text” name=”j_username”>
<input type=”password” name=”j_password”>
</form>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.jsp</form-error-page>
</form-login-config>
</login-config>
2、你的form有特别格式。
<form method=”POST” action=”j_security_check”>
<input type=”text” name=”j_username”>
<input type=”password” name=”j_password”>
</form>

Sorry,我的回答方向错误 :)
你如果是访问基于认证的网站用楼上路人甲的方法是可行的。
如果是访问基于form的网站(不是认证的,就是简单的getParameter的话),直接把参数传过去即可。
#5
路人甲的方法我试了一下,结果是"java.io.IOException: Server returned HTTP response code: 403 "
不知道路人甲老兄用的Base64.encode是哪个package里的,我随便找了一个,也不知有没有问题

还有CGIurl是怎么new出来的?
我写的是URL url = new URL("http://localhost:88/NASApp/myapp/myservlet");
