2011-3-20 10:03:33 org.apache.catalina.core.StandardContext start
严重: Error filterStart
2011-3-20 10:03:33 org.apache.catalina.core.StandardContext start
严重: Context [/suppjxc] startup failed due to previous errors
2011-3-20 10:03:33 org.apache.catalina.core.ApplicationContext log
信息: Closing Spring root WebApplicationContext
2011-3-20 10:03:33 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
严重: The web application [/suppjxc] registered the JBDC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
2011-3-20 10:03:33 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
严重: The web application [/suppjxc] appears to have started a thread named [Timer-10] but has failed to stop it. This is very likely to create a memory leak.
解决方案1: 类转换异常，看看你的那个STRUTS-DEFALUT.XML文件，在看看ConfigurationManager这个类
解决方案2: 仔细检查下 web.xml和struts.xml两个配置文件
解决方案3: 路劲不合适吧！
解决方案4: Unable to load configuration. - [unknown location]
解决方案5: opensymphony找不到配置文件
以上介绍了“ 请问高手们这是什么错？帮忙解决下，谢谢”的问题解答，希望对有需要的网友有所帮助。
