路徑問題：在struts的package（preparation/Piping/PidinitAction.action）路徑下的頁面裡有個URL，
   是連線到其他struts的package下的（preparation/BasicData/SysSubSyspartAction.action），
   如果url直接寫為

var url = 'preparation/BasicData/SysSubSyspartAction.action?currentTimeSerial='+mill+'&fancybox=1';

它會提示
The requested resource (There is no Action mapped for namespace /preparation/Piping and action name SysSubSyspartAction.) is not available.
需要

var url = '<%=request.getContextPath()%>/preparation/BasicData/SysSubSyspartAction.action?currentTimeSerial='+mill+'&fancybox=1';
 

即加上<%=request.getContextPath()%>/ 才能找到路徑。
