如何使用jdk 1.6.0_20在Eclipse 3.6中配置tomcat 7？

Question

我在Eclipse 3.6上配置tomcat 7時遇到了一些問題。環境是o.s.的筆記本。 Windows 7家庭高級版64位。 在此升級之前，我在Eclipse 3.6上使用tomcat 6成功工作，但是我在新tomcat上的開關是一個邪惡！我重複我用來配置tomcat 6的每條指令，但它不起作用！

如果我在eclipse中啓動tomcat而沒有安裝受監視的應用程序，它可以工作，因爲我添加了一個應用程序，它崩潰了。我錯過了什麼？

這裏的Tomcat日誌：

Answer 1

似乎有是在WTP 3.2的問題，結合Tomcat的7這個問題在this topic在Eclipse的論壇上進行了討論。的原因及解決方法描述如下：

它出現在啓動過程已在Tomcat的改變7，使得 <ResourceLink>，當在server.xml中一個<context>的一部分，被所述服務器之前處理 被充分初始化。如果你在Eclipse中打開服務器 編輯器並且啓用「發佈模塊上下文來分開 XML文件」選項，我相信你會避免這個問題。我將看到有關 強制爲WTP 3.2.1中的Tomcat 7服務器啓用此選項。
