RE: No ActionForm Bean Required

[Tewathia, Atul]

I feel there is some problem.
I tried the same thing but I get the following error on console. It shows
that it is trying to instantiate a form bean corresponding to an action
mapping. And if i am not specifying one it gives an error. How do I handle
this situation when I don't need a form ???

OneForm instantiated
TwoaeForm instantiated
TwokeyForm instantiated

You don't have to specifiy an ActionForm if you don't need one.
Watch the LogoffAction in the example shipped with struts:

<!-- Process a user logoff -->
<action path="/logoff"
        type="org.apache.struts.example.LogoffAction">
        <forward name="success"              path="/index.jsp"/>
</action>

Hope this helps,
