Don't you still have to set the "parameter" using the MappingDispatchAction
class?
One way to do what you want (i.e. not specify the parameter) is to create
your own custom ActionMapping and override the getParameter() method with
some logic to look at the path and return the parameter based on it.
Something like:
public class ParameterActionMapping extends ActionMapping {
public String getParameter() {
if (path.endsWith("Create"))
return "create";
if (path.endsWith("Read"))
return "read";
if (path.endsWith("Update"))
return "update";
if (path.endsWith("Delete"))
return "delete";
return super.getParameter();
}
}
Then in struts-config.xml you can use this mapping for all your actions by
setting the type:
<action-mappings type="myPackage.ParameterActionMapping">
or on indivdual actions using the className
<action className="myPackage.ParameterActionMapping" ...
