If you're willing to have struts update the model directly, you can nest your model under a getter property in an object that extends ActionForm. eg: getMyDataModel() From the property down, there never needs to ba any reference to struts again, besides the methods that provide usually simpler object types than the ones you need. However, you can usually write simple conversion code inside the objects that can turn it into something more useful when you need it. This way, the entire process is automatic, and doesn't any property copying/transfer.
In the JSP side of things, you can just write the nested version of the property. eg: <html:txt name="myStuff" property="myDataModel.propertyInTheModel" /> If you want to go this way, I've heard that there's a nesting extension to make this easier too. ;) Arron.
