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时遇到了一些问题。环境是o.s.的笔记本。 Windows 7家庭高级版64位。 在此升级之前，我在Eclipse 3.6上使用tomcat 6成功工作，但是我在新tomcat上的开关是一个邪恶！我重复我用来配置tomcat 6的每条指令，但它不起作用！

如果我在eclipse中启动tomcat而没有安装受监视的应用程序，它可以工作，因为我添加了一个应用程序，它崩溃了。我错过了什么？

这里的Tomcat日志：

似乎有是在WTP 3.2的问题，结合Tomcat的7这个问题在this topic在Eclipse的论坛上进行了讨论。的原因及解决方法描述如下：

它出现在启动过程已在Tomcat的改变7，使得 <ResourceLink>，当在server.xml中一个<context>的一部分，被所述服务器之前处理 被充分初始化。如果你在Eclipse中打开服务器 编辑器并且启用“发布模块上下文来分开 XML文件”选项，我相信你会避免这个问题。我将看到有关 强制为WTP 3.2.1中的Tomcat 7服务器启用此选项。
