this patch is for using ErrorsTag in wls 6.0.
the ErrorsTag gets MessageResources out of the ServletContext (or
application scope, take your pick of terminology) on line 183.
weblogic server 6.0 (apparently) serializes (or deserializes) the
attributes in ServletContext. MessageResources has a reference to a
MessageResourcesFactory which is not serializable, and so it bombs when
taking the MessageResources out of the ServletContext. (why not when
they are put in? i don't know.)
i have attached a stack trace for the skeptical.<grin>
in any event, making MessageResourcesFactory serializable resolves this
issue for wls 6.0.
