先简述一下系统使用的技术，框架是struts1.2,action继承LookupDispatchAction，页面的验证使用validation，应用服务器为jboss4.2
问题描述:
在web.xml配置文件中配置了实现域登录的Servlet后出现如下问题:
点击系统的“增加”按钮弹出的页面中的“保存”按钮无法调用action中对应的方法；
“修改”按钮弹出页面的“保存”则出现如下错误
WARN [RequestProcessor] Unhandled Exception thrown: classjavax.servlet.ServletException
INFO [[/]] Request[/doc/docmanagedetailaction] does not contain handlerparameter named 'act'. This may be caused by whitespace in the label text.
jsp页面中的“保存”按钮代码
<html:submit styleClass="button" property="act"onclick="return chkpagecount();">
<bean:message key="button.save" />
</html:submit>
实现域登录的Java文件(http://www.jcifs.com/可以下载相应的jar包)

若要解决此问题，从客户端，使用注册表编辑器 (Regedt32.exe) 将值添加到以下注册表项：
HKEY_CURRENT_USER/软件/microsoft/windows/CurrentVersion/internet设置 /
注意上面的注册表项是一个路径，它经过了折行以提高可读性。
添加以下注册表值：
值名称： DisableNTLMPreAuth
数据类型： REG_DWORD
值： 1
除了注册表项还需要关闭 Internet Explorer 中 启用集成 Windows 身份验证。 若要这样做，请按照下列步骤操作：
启动 Internet Explorer。
单击 工具，请单击 Internet 选项，然后单击 高级 选项卡。
在 安全，下单击以取消选择 启用集成 Windows 身份验证 (需要重启动)，然后单击 应用。
关闭 Internet Explorer。
若要解决此问题，从服务器端，配置网站以使用下列身份验证方法之一：
若要允许匿名访问仅网站进行配置。
配置为允许匿名访问和 NLTM 身份验证 （集成 Windows 身份验证） 的网站
