MyEclipse6.5增加对Tomcat7的支持

最近在研究Servlet3.0，它是JavaEE6.0规范中的一部分

而Servlet3.0对服务器是有要求的，比如Tomcat7+(而Tomcat7.0要求JDK6+，即编译级别应该是6+)

但我一直使用的MyEclipse6.5不支持Tomcat7，可也不能为了这个就去装一个MyEclipse8.0啊

好吧，还是像当初我用TongWeb5.0的方式一样，自己DIY一下吧

1)下载Tomcat7
2)由于我已经配置了tomcat6，为了同时拥有tomcat6和tomcat7的环境，所有我们在MyEclipse的Tomcat5.x里配置tomcat7
  MyEclipse-->Window-->Preferences-->MyEclipse Enterprise Workbench-->Servers-->Tomcat-->Tomcat5.x
  Tomcat5.x-->Enable
  Tomcat5.x-->Tomcat home directory-->D:Developapache-tomcat-7.0.41
  Tomcat5.x-->JDK-->Tomcat JDK name-->jdk1.6.0_45
3)第二步配置完，在MyEclipse6.5的Servers视图里启动Tomcat5.x(实际为tomcat7.0.41)会发现弹出一个对话框
  Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit.
  同时MyEclipse6.5控制台会输出下面的异常信息
  java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
  	  at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:60)
  Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory
	  at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
	  at java.security.AccessController.doPrivileged(Native Method)
	  at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
	  at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
	  at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
	  at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
	  ... 1 more
4)所以我们还要修改一下
  Tomcat5.x-->Paths-->Append to classpath-->把D:Developapache-tomcat-7.0.41bintomcat-juli.jar加进去-->Apply-->OK
  然后再启动Tomcat5.x(实际为tomcat7.0.41)会发现启动成功！！浏览器访问http://127.0.0.1:8080/成功！！

下面是控制台输出
