I would create a constructor in the action, and place a
breakpoint/logging statement in there to make sure the correct action is
beng called. In the HTML you have:
<s:form action="Logon" name="login_form" >
So the action should be /Logon.action, but your configuration is:
<action name="Logon_*" method="{1}" class="packagename.Logon">
Which would seen to imply that the action attribute in the form should
be "Logon_login".
