SEVERE: Parse error in application web.xml java.lang.IllegalArgumentException: Servlet mapping specifies an unknown servlet name Ch3 beer at org.apache.commons.digester.Digester.createSAXException(Digester.java
That says your web.xml is badly formed. Doublecheck the lines that are supposed to associate a servlet name with the servlet class. Bill
