------解决方案--------------------
Cannot retrieve mapping for action /showAll
action配置文件里没找到/showAll这个action
------解决方案--------------------
Cannot retrieve mapping for action /showAll
意思是找不到/showAll 对应的action,
检查struts配置文件的action路径对不对啊，
- XML code
<action [b]path[/b]="/????"<!-- 这个路径 --> type="....." validate="false"> </action>
