Struts + tomcat 5出现在奇怪问题
初学struts,在调第一个小应用时,首页可以正常显示,当点提交时出现如下错误:
HTTP Status 404 - Servlet action is not available
type Status report
message Servlet action is not available
description The requested resource (Servlet action is not available) is not available.

以下为web.xml文件:

以下是index.jsp代码:

<h3> what will showed this time? </h3>
<center>
<html:form action= "/test " method= "POST ">
<table width= "350 " border= "0 " cellpadding= "3 " cellspacing= "0 ">

<td align= "center "> <html:submit/> </td>

</table>
</html:form>
</center>
</body>
</html>
-------------------------
index.jsp可以正常显示,在输入数据后,点 "提交 ",就会出现错误.浏览器地址显示为:
http://localhost:8080/struts-base/test.do(地址正确)
谢了先~~~~
[解决办法]
<html:form action= "/test " method= "POST ">
改成
<html:form action= "/test.do " method= "POST ">
试试
[解决办法]
404错误是没有找到指定的JSP文件~
[解决办法]
这个问题解决了吗？和我遇到的一样~有哪个大哥来指点一下
[解决办法]
看看你的struts的jar包是不是都在lib下面。
[解决办法]
给点建议，互相学习
1、看看你的action是不是继承而来，或者是不是继承错对象了；
2、JAR包是不是少了；
3、struts-config.xml是否放在WEB-INF目录下；
4、你的Form是直接指向了org.apache.struts.validator.DynaValidatorForm。
那你在jsp中元素肯定不会有GETTER方法，建议从DynaValidatorForm继承出一个新类包含你表单中需要的元素；
