  • Well, obviously it can find class `gov.da.jmrs.webapp.filters.AuthenticationFilter`. Is that your own class? If not, then you forgot to add the `.jar` file that contains it to the `WEB-INF/lib` folder of the `.war` file. If it is yours, then you forgot to add it to the `.war` file as `WEB-INF/classes/gov/da/jmrs/webapp/filters/AuthenticationFilter.class`. – Andreas Dec 07 '17 at 03:38

Check your classpath, missing class to the classptah. Read this topic to know more How do I resolve ClassNotFoundException?
