Hi,
Struts 1.0 and 1.1 The new features added to Struts 1.1 are RequestProcessor class Method perform() replaced by execute() in Struts base Action Class Changes to web.xml and struts-config.xml Declarative exception handling Dynamic ActionForms Plug-ins Multiple Application Modules Nested Tags The Struts Validator Change to the ORO package Change to Commons logging Removal of Admin actions Deprecation of the GenericDataSource Struts 1.2 to 1.3 Opt-In Cancel Handling In Struts 1.2 and prior, any time the magic token generated by the Cancel tag is found in the request, validation for the ActionForm is skipped. Accordingly, in Struts 1.2 and prior, any Action that relies on validation should always observe the isCancelled method. In Struts Action 1.3, the Cancel token is only honored if the new property "cancellable" is set for the Action Mapping. If the Cancel token is present, but cancellable is not set, then an InvalidCancelException is thrown. The InvalidCancelExeption may be caught by a Declarative Exception Handler, like any other Exception. Jars I guess its obvious to say you need to replace the jars, but the one people might forget is the new commons-validator.jar for version 1.1.3 of validator. Also if you want to start using the new validwhen validation rule, then you will need to deploy the antlr.jar as well. New URI Struts 1.1 <%@ taglib uri="http://jakarta.apache.org/struts/tags-html prefix="html" %> Struts 1.2.x <%@ taglib uri="http://struts.apache.org/tags-html prefix="html" %> Specification Changes The 1.3.x series of Struts Action Framework now has a minumum requirement of the following specification versions: Java Servlet 2.3 and JavaServer Pages (JSP) 1.2 Java 2 Standard Platform Edition (J2SE) 1.4 Kind regards, Rakesh Bhat
