Hi after ggogling these names you get nothing and certainly not any java doc links ... because these interfaces do not exist its ServletRequestListener rather than HttpServletRequestListener ...... i just found out about this !!
hi if you refer ...\webapps\tomcat-docs\servletapi-you can find that there is no class named HttpServletRequestListener and HttpServletRequestEvent.there is only ServletRequestListener and ServletRequestEvent
