大家帮我看看我这段代码错误在哪里呢？

meiqianmeifang 2008-06-11 09:20:37

<struts-config>中定义了：

<action
attribute="uploadForm"
input="/form/upload.jsp"
name="uploadForm"
path="/upload"
scope="request"
type="com.yourcompany.struts.action.UploadAction" />

但是在jsp中用的时候
<html:form action="/upload"> </html:form>

却显示错误呢？究竟错在哪里呢？

[Quote=引用 7 楼 whetu 的回复:]
你用的是struts1,3楼说的对，打开你的web.xml，找到struts的ActionServlet配置项的url，可能是*.do也可能是*.action或者是任何自定义标示,比如*.abc。确认一下，然后 <html:form action="upload.abc">

楼上说的正确，看看你的web.xml是不是这么配置的
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

你的web.xml中ActionServlet配置url是*.do的话就下面这样写,具体得看你url怎么写的
<html:form action="/upload.do"></html:form>
