錯誤Esper XML DOM文檔

我有Esper框架的問題。尋找一個解決方案之後，我發現從官方網站的例子：錯誤Esper XML DOM文檔

http://esper.codehaus.org/esper-4.11.0/doc/reference/en-US/html/examples.html#examples-autoid

這個例子的源代碼可以在這裏找到：在例子\自動識別DIR http://esper.codehaus.org/esper/download/download.html。

當我運行這個例子時，我得到以下錯誤。任何幫助將不勝感激。

我想這個問題是艾斯波不支持JRE 1.7完全，與XML和DOM工作時。安裝1.6，一切開始工作。 –

這是一個已知的問題與Java 7更新45，嘗試更新25 見http://jira.codehaus.org/browse/ESPER-764

看來他們在這個框架中有版本兼容性的巨大問題。我們安裝1.6 JRE適合我。 P> S 對不起，我不能提供您的答案 - 沒有足夠的評價:) –

這是一個已知的Java問題，Oracle在JDK7中引入並在最新版本的JVM中修復。 – user650839
