New ActionMapping Class

[Michael Binette <mb...@mediaone.net>]

I created a new GenericActionMapping class that extends ActionMapping.  I
added one property, processAction with public getter and setter methods for
it.

I then set the mapping property in web.xml for the struts Action servlet to
my new GenericActionMapping class.  The log when I run TomCat correctly
shows it using my new GenericActionMapping class.

But, if I add processAction="whatever" to my struts-config.xml, within the
<action> element, I get a SAXParseException, Attribute "processAction" is
not declared for element "action".

How do I get this to work?

Great.  It worked.

I am using this so that I can easily use one action class for multiple
actions such as "view", "edit", "delete" and "save", where it makes sense.
I wanted multiple Action mappings such as /editUser.do and /saveUser.do but
have them both use the same Action class.

I used your Transport idea and created an ActionInfo class to contain
properties with the mapping, request, response, form, and my new
processAction properties.

I also created a GenericAction that extends Action, sets up the ActionInfo
and calls an abstract method processAction(ActionInfo actionInfo).

Hopefully this will save me from the many Action classes per jsp view.

I've created a ViewSubmitAction that extends my GenericAction that looks at
the processAction and calls either processView(ActionInfo actionInfo) - an
abstract method of ViewSubmitAction, or processSubmit(AcitonInfo
actionInfo) - which can take care of all other cases.

anyways...  Thanks for the tip.

You need to use a <set-property> tag is Struts-config.xml

For example:

<action path="/this" name="myForm" type ="myPackage.myAction">
  <forward name="success" path="/next.jsp"/>
  <forward name="fail" path="/prev.jsp"/>
  <set-property property="processAction" value="whatever"/>
</action>

This error happens because your struts-config.xml document now violates
the DTD.

That's what the <set-property> element is for:

    <action path="..." ...>
      <set-property property="processAction" value="yadda yadda"/>
    </action>

This little trick lets you extend the syntax of an ActionMapping, and add
new configurable properties, without having to modify the DTD.
