struts<html:form>标签问题 在线等 解决立即给分
新手学struts 在jsp页面想用一个表单，可是一用到＜html:form> </html:form> 标签就出现问题～希望各位高手帮帮我这菜鸟．多谢各位大虾了．
我用的是struts 的标准框架．struts.war解压出来的．
jsp 页面的代码
<%@ page contentType= "text/html;charset=GB2312 " %>
<%@ taglib uri= "/tags/struts-bean " prefix= "bean " %>
<%@ taglib uri= "/tags/struts-html " prefix= "html " %>
<%@ taglib uri= "/tags/struts-logic " prefix= "logic " %>
<html:form action= "/Register.do " focus= "userName ">
<html:text property= "userName "/>
<html:text property= "pwdf "/>
<html:text property= "pwds "/>
<html:text property= "nickName "/>
<html:text property= "sex "/>
<html:text property= "email "/>
<html:text property= "cardId "/>
<html:text property= "level "/>
<html:text property= "registerDate "/>
<html:submit property= "submit " value= "提交 "/>
<html:reset/>
</html:form>
下面是错误代码：

但是要是把jsp页面的代码换成下面的就能显示：
<%@ page contentType= "text/html;charset=GB2312 " %>
<%@ taglib uri= "/tags/struts-bean " prefix= "bean " %>
<%@ taglib uri= "/tags/struts-html " prefix= "html " %>
<%@ taglib uri= "/tags/struts-logic " prefix= "logic " %>
＜html:submit/>
[解决办法]
在struts config xml 中，看看 你的RegisterForm 有没有定义
[解决办法]
你使用 <html:form> 标记就必须在struts-config.xml中配置 <form-beans>
[解决办法]
如果你在Action 里定义了name= "RegisterForm "那么，你必须在 <form-beans> </form-beans> 中定义这个RegisterForm
[解决办法]
把 <html:form action= "/Register.do " focus= "userName ">
改成 <html:form action= "Register.do " focus= "userName "> 试试
[解决办法]
<html:form action= "/Register.do " focus= "userName ">
改一下，去掉 "/ "： <html:form action= "Register.do " focus= "userName ">
[解决办法]
看一下， 你有没有定义RegisterForm这个java类，如果你没有定义这个类的话，肯定会报这样的错误
[解决办法]
你FORM里的ACTION 写错了
要么写成
<html:form action= "Register.do " focus= "userName ">
或者
<html:form action= "/Register " focus= "userName ">
[解决办法]
<html:form action= "Register.do " focus= "userName " method= "POST ">
[解决办法]
是你检查Register.jsp里面错误可能有语法错误什么的 你要插入数据库的字段插入进去了吧
[解决办法]
<html:form action= "/Register.do " focus= "userName ">
为什么不行 我就是这么用 可以找到的
[解决办法]
把 <html:form> 标签前加上 <html:html>
</html:form> 后加上 </html:html>
[解决办法]
myplat.web.struts.form下存在RegisterForm？？
别计较FORM那里问题了 用那种方法都是可以的
