从eclipse中启动tomcat和直接启动tomcat,该怎么处理

从eclipse中启动tomcat和直接启动tomcat
我做struts的程序，从eclipse中启动tomcat，网站可以正常运行(当时环境变量中没有设置tomcat相关的东西)。  
如果关掉eclipse，直接启动Monitor   tomcat，页面报错。  

还有，我在两天前直接启动Monitor   tomcat运行一个下载的网站，可以成功运行。  
昨天就启动不起来了，页面报错。下载的那个东西肯定没有改过。环境（jdk   tomcat）也没动过，这个问题比较奇怪,是系统问题还是环境有所改变。  

在环境变量中配置了一下
CLASSPATH＝.\;%JAVA_HOME%\lib;D:\Program   Files\Apache   Software   Foundation\Tomcat   5.0\common\lib;D:\Program   Files\Apache   Software   Foundation\Tomcat   5.0\webapps\test\WEB-INF\classes

path==%JAVA_HOME%\bin;%PATH%;C:\Program   Files\ThinkPad\Utilities;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program   Files\Intel\Wireless\Bin\;C:\Program   Files\IBM   ThinkVantage\Client   Security   Solution;C:\Program   Files\ThinkPad\ConnectUtilities

希望高手解答，谢谢了。
 
http://localhost:8080/test/a.html这都能运行，http://localhost:8080   Tomcat欢迎画面，管理都能运行。我感觉是程序的问题？但在MyEclipse中启动tomcat就没有任何问题？
