This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
In Struts 2, you no longer use a special class to represent an error. Errors are just Strings. If you want your Action to return error messages to the JSP, have it implement the interface ValidationAware or have it extend ActionSupport or ValidationAwareSupport. See the javadoc for more information. [ September 18, 2007: Message edited by: Merrill Higginson ]
