What does the web page where you get the java.io.NotSerializableException look like?
I tried playing around with the javax.faces.context.Flash features on the http://jsf2gae.appspot.com/ site. The first page, flash.xhtml, has the following source: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> <html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en" xmlns:f="http://java.sun.com/jsf/core"; xmlns:h="http://java.sun.com/jsf/html"; xmlns:ui="http://java.sun.com/jsf/facelets";> <h:head id="head"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Example of JSF 2.0 Flash Functionality</title> </h:head> <h:body id="body"> <h:form> <p>Value for Next Page <h:inputText value="#{flash.myValue}" size="25" maxLength="25"/></p> <p> <h:commandButton id="submit" action="flash_page2" value="Next page"/> </p> </h:form> </h:body> </html> The second page, flash_page2.xhtml, has the second contents: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> <html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en" xmlns:f="http://java.sun.com/jsf/core"; xmlns:h="http://java.sun.com/jsf/html"; xmlns:ui="http://java.sun.com/jsf/facelets";> <h:head id="head"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Example of JSF 2.0 Flash Functionality (Page 2)</title> </h:head> <h:body id="body"> <p>You typed "<h:outputText value="#{flash.myValue}"/>".</p> <p><h:outputLink value="flash.jsf">Start Over</h:outputLink></p> </h:body> </html> It works without generating any errors. Derek P.S. The "Flash" features are a great, quick way to pass data from one page to another!
