I am trying to implement a catch all for error handling, and I am trying to follow the advice posted in the Knowlesge Base: http://seamframework.org/Documentation/UnifiedErrorPageAndExceptionHandling
However the jsp page does not compile as it cannot resolve any of the Java types. This includes the page imports
<%@ page import="java.io.PrintWriter" %>
The import java.io.PrintWriter cannot be resolved
Am I obviously missing something fundamental in my classpath. Do I need to copy existing jar files from the classpath to web-inf/classes? Or is it something else?
thanks in advance
Would this have anything to do with JBoss Developer Studio (Eclipse) handling/ validation of jsp's?
