为什么struts对应的action访问资源不可用？几天都郁闷

[shenzhenNBA]

首先是做一个struts例子，里面有几个action类，怎么对应的访问资源(如 http://pcName:8080/J2EE01/Login.do)都不可用，struts-config.xml文件确认已经读取了，这个是什么原因？ 困扰几天了都搞不定？郁闷之极...求大伙帮看是什么原因？下面分别是各个文件（注意：这个大小写之类的问题我已经注意；奇怪我另建立一个简单的project来测试，只有一个Login action，对应的访问资源/Login.do 又可以成功访问）

struts-config.xml文件确认已经读取了,那可能是路径问题，试着访问：http://pcName:8080/J2EE01/Login/Login.do

还有个问题今晚跑去书店大致看了一下 struts 2 冒似相对简单，那 Eclipse 3.2.0版本 MyEclipse 5.1版本 可以用来建立 struts 2 的环境吗？ ，请高手帮看看....


struts 1.1版本中,配置文件 struts-config.xml 中的为什么 data-source 和action等元素含有 set-property子元素时系统就不能读取该struts配置文件，其中 set-property 元素是使用MyEclipse 开发环境生成，应该不成问题？但为什么就不能读取呢？请高手帮看看....

[shenzhenNBA]

2L 说的那个情况，应该不是

今天新发现：

struts 1.1版本中,配置文件 struts-config.xml 中的为什么 data-source元素包含 set-property元素时系统不能正常读取该配置文件，其中 set-property 元素是使用MyEclipse生成，应该不成问题吧？发现其它元素包含 set-property 元素时也struts系统也不能正常读取该配置文件？以下红色部分去掉就可以正常读取了，
如果不能使用 set-property 那也就是说不能使用struts的数据库连接池，（意味着DB连接得重写而不能使用struts现成）
这个是什么原因？ 如何使用struts的数据库连接池呢？求高手帮解答

报什么错呀，贴出来看看再说，是404还是别的
