请教用eclipse + tomcat +lomboz 开发jsp时的问题？

各位大侠：
我机器的环境是eclipse + tomcat +lomboz 环境也配置成功了，但是在开发的时候出现这样的问题，一直捆饶我，如下：
严重: Error starting static Resources
java.lang.IllegalArgumentException: Document base D:\Tomcat 5.0\webapps\balancer does not exist or is not a readable directory
严重: Error in resourceStart()
2006-7-16 14:38:16 org.apache.catalina.core.StandardContext start
严重: Error getConfigured
2006-7-16 14:38:16 org.apache.catalina.core.StandardContext start
严重: Context startup failed due to previous errors
2006-7-16 14:38:16 org.apache.catalina.core.StandardContext start
严重: Exception during cleanup after start failed
LifecycleException: Container StandardContext[/balancer] has not been started
请问怎么解决啊？
