开发环境是myEclipse，已经正确配置filter，但是无法访问，tomcat启动报错
下面是web.xml文件：
<filter><filter-name>MyFilter</filter-name><filter-class>com.jwos.filter.MyFilter1</filter-class></filter>
<filter-mapping><filter-name>MyFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>
<servlet>
<description>This is the description of my J2EE component</description>
<display-name>This is the display name of my J2EE component</display-name>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>com.jwos.controller.LoginServlet</servlet-class>
</servlet>
报错信息：
java.lang.ClassNotFoundException: com.jwos.filter.MyFilter1
死活无法加载，重启，重新部署都不行
我的filter文件：
