我正在嘗試集成Struts2 ver 2.5.2，DWR ver 2.0,5和Sitemesh ver 2.5。我的DWR（幾乎）已經正常工作。我可以打開[CONTEXT] /dwr/engine.js和util.js，還可以打開[CONTEXT] /dwr/interface/Arithmetic.js。集成Struts2 Sitemesh DWR
問題是，當我打開包含dwr調用的index.jsp時，並未定義dwr js變量以及算術變量。
index.jsp本身已經從Sitemesh過濾器裝飾過。

如果我評論filter-mapping sitemesh ---- DWR調用將工作得很好。所以我認爲，該請求將由SitemeshFilter過濾，奇怪的是它不會去DWR過濾器。我試圖搜索如何按順序排列過濾器，但沒有出現。任何幫助讚賞。十分感謝。
