Yes. If your Action does not need any data and it does not need to make any data available to the view or controller component that it forwards to, it doesn't need a form. A good example of an Action with no ActionForm is the LogoffAction in the struts example application:

<action path="/logoff"
type="org.apache.struts.webapp.example.LogoffAction"&GT;
<forward NAME="SUCCESS" path="/index.jsp"/>
</action>

This action NEEDS no data other than the user's session, which it can get from the Request, and it doesn't need to prepare any view elements for display, so it does not need a form.

However, you cannot use the <html:form> tag without an ActionForm. Even if you want to use the <html:form> tag with a simple Action that does not REQUIRE input, the tag will expect you to use some type of ActionForm, even if it is an empty subclass without any properties.
