Comments on: Creating a DTO DSL With ANTLR 3 http://daniel.gredler.net/2007/12/10/creating-a-dto-dsl-with-antlr-3/ Tue, 24 Jan 2012 01:02:16 +0000 hourly 1 http://wordpress.com/ By: Timo Westkämper http://daniel.gredler.net/2007/12/10/creating-a-dto-dsl-with-antlr-3/#comment-442 Fri, 22 Feb 2008 12:28:28 +0000 http://daniel.gredler.net/2007/12/10/creating-a-dto-dsl-with-antlr-3/#comment-442 Alternatively you might just declare classes like this :

public class ReceptacleDto {
…
/** The name of the receptacle type. */
String type;
/** The receptacle’s gross weight. */
Quantity grossWeight;
…
}

and use CGLIB to construct proxy subclasses with accessors for the fields. Any other metadata you can provide via annotations.

Binding to fields with no public visibility is not so convenient in Java code, but the accessors can be used when binding and access happens via reflection (e.g. usage in view templates or Dozer)

Inside the jvm can just use the BO / models directly right up to the mvc layer.

Construct a xml with property name and comment etc. appy xslt’s and u r done. i developed it for one of my previous projects.
