在網上google半天也沒見人解決，還是看了FilterDispatcher的源碼才解決，特地貼到blog上，備忘吧。
在com.opensymphony.webwork.dispatcher.FilterDispatcher中有以下代碼
1?????????????if?("true".equals(Configuration.get(WebWorkConstants.WEBWORK_SERVE_STATIC_CONTENT))?
2?????????????????????&&?resourcePath.startsWith("/webwork"))?{
3?????????????????String?name?=?resourcePath.substring("/webwork".length());
4?????????????????findStaticResource(name,?response);
5?????????????}?else?{
6?????????????????//?this?is?a?normal?request,?let?it?pass?through
7?????????????????chain.doFilter(request,?response);
8?????????????}
也就是說，只要webwork.properties文件中webwork.serve.static=true（系統默認），并且FilterDispatcher這個過濾器對/webwork/*這個url進行了處理的話，就不會發生使用ww2提供的
datepicker時，找不到/webwork/*下所有的js、image等資源，不得不手工拷貝webwork.jar中/com/opensymphony/webwork/static為/webwork/*的情況。
