运行程序时出现问题：This release of Apache Tomcat was packaged to run on J2SE 5.0
or later. It can be run on earlier JVMs by downloading and
installing a compatibility package from the Apache Tomcat
binary download page.
遇到这个问题,上网搜了一下,所以摘录下面的这篇文章.

装了个Tomcat
今天在安装Tomcat的时候，少有波折，上网一看同样问题的人还不少，初学的同志很多嘛。
原来已经安装好jdk1.4，使用正常。在装上Tomcat5.52后，本地服务器无法浏览。查看错误提示，是
“Neither the JAVA_HOME nor the JRE_HOME environment variable is defined At least one of these environment variable is needed to run this program ”
是java_home和jar_home没有设置，在环境变量里添加这两个变量。
以为万事大吉，再startup.bat，还是不行，这次是“This release of Apache Tomcat was packaged to run on J2SE 5.0 or later. It can be run on earlier JVMs by downloading and installing a compatibility package from the Apache Tomcat binary download page.”
应该是说jdk版本太低了
去下载个jdk1.5，重新装起来后修改一下java_home和 jre_home等相关的变量就OK了。
