我已經配置在Eclipse中的默認服務器和lib文件夾中添加的jar文件到path.Placed的jar文件。

嗯，幾乎看起來好像當它試圖爲配置文件檢索'.dtd'時發生問題。也許你可以嘗試將DTD複製並粘貼到配置文件的頂部，並查看錯誤是否消失。當然，這不是一個很好的「解決方案」，但是如果它能起作用，那麼你就有了一些工作和解決問題的線索。 – rees

我不認爲我有解決方案。我沒有使用任何DTD。 – Rodex

你沒有使用struts.xml文件嗎？如果您正在使用它，那麼它可能以'<！DOCTYPE struts PUBLIC 「的形式引用頂部的dtd - // Apache Software Foundation // DTD Struts配置2.3 // EN」「http：// struts。 apache.org/dtds/struts-2.3.dtd「>」。將其替換爲dtd內容（您可以從URL下載）。對任何你有的配置文件做這個，struts.xml，validation.xml文件等。 – rees

如果你收到這樣

異常產生的原因：的java.net.UnknownHostException：Struts2的XML配置的建設過程中struts.apache.org

，那麼某些原因造成應用程序成功檢索DTD。

從

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">

更改DOCTYPE聲明到本地參考或直接複製粘貼的DTD內容到原來的位置將解決此問題。

我想指出這一點。我使用的是struts2-jfreechart-plugin-2.3.4.jar，它的struts-plugin.xml DTD是2.3，而我在Struts.xml中使用的是2.0。所以下載了struts2-jfreechart-plugin-2.1.8.jar並替換了它。從而解決了這個問題。謝謝@rees。 – Rodex
