Help! JSF keeps barfing: Non-serializable attribute

[Philippe Desrosiers]

I keep getting the following exception whenever I try to hit a JSF page:

java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute
org.apache.catalina.session.StandardSession.setAttribute(StandardSession.java:1255)

The code of my JSF page is pretty simple:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<f:loadBundle basename="messages" var="msg"/>
<f:view>Hi there!</f:view>

What the hell could I possibly be doing wrong?

Maybe it can't find your messages.properties file?

Anyway is this the same or different than in your other post about Login?

It seems to be the same.

Nope. Different. It turns out that if you have a <distributable/> tag in your web.xml, JSF barfs. Apparantly this is a Tomcat thing, not a JSF thing.
