和web.xml继续奋斗HTTP Status 500 – Internal Server Error

本文主要是介绍和web.xml继续奋斗HTTP Status 500 – Internal Server Error，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

和web.xml继续奋斗
上次报了Proxool池连接错误，就在web.xml里加入了

	<!-- start proxool连接池 --><servlet><display-name>proxool</display-name><servlet-name>ServletConfigurator</servlet-name><servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class><init-param><param-name>xmlFile</param-name><param-value>WEB-INF/proxool.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet><servlet-name>wkxtAdmin</servlet-name><servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class></servlet><servlet-mapping><servlet-name>wkxtAdmin</servlet-name><url-pattern>/wkxtAdmin</url-pattern></servlet-mapping><!-- end proxool连接池 -->

然后又报了另一个错误。
