Yeah, Restlet project was one of the first frameworks on the stage for easing development of applications following the rest architectural style, in fact the guy behind restlet (Jerome?) is a member of the expert group for JSR 311.
Object mapping (Object <-> XML/JSON,...) may seem the most boring thing that is necessary, but with the libraries today and the abstractions that were built on top of those libraries, it's not that complicated... some frameworks can do this mapping automatically for you, and you don't even need to touch XML or JSON in your server code, or even be aware of that while coding your objects. Of course, if you have a complex object model and want to expose that complexity to the client, then... good luck :)What do you mean by REST functionality?

While recent versions of Java EE ease the development of Web-Services, the same doesn't happen with true REST applications. Working with XML and JSON is a pain in the ass if you don't use tools as Xstream and Gson but the real issue is with the REST functionality itself. I'd recommend you to take a lot at restlet.org.

Hello,

I have been trying to get in touch with you for an update regarding our business proposal. I have not had much luck, so unless I hear otherwise.
Or perhaps that my emails might have been caught by any spam filters.

Please let me know if you have any concerns or general feedback regarding our proposal or business sponsorships.

Regards,
Jason

This is a great way to decide which type of class to instantiate. I had found an additional method using something like this ' @structure = params[:type].constantize.new'

joaomrpereira — Sat, 05 Feb 2011 17:35:03 -0000

Hi Cesar, how're doing?

I like it and generally reflection is used to implement some kind of framework code, i.e., you build a framework to do validations for example, then you'll expose it though an API to the world and they don't even know that the API was implemented with reflection... now, if you ever see reflection being used directly in you business logic, well....

Cesar Alvernaz — Sat, 05 Feb 2011 17:17:40 -0000

Hi Joao :)

From languages that I've already did some stuff, Java is undoubtedly the easiest and expressive API (mostly), but in the particular case of reflection I can't share the same opinion. It is a very powerful and useful mechanism, but the way how is exposed is awful. It turns out that, to make generic and clean code using reflection we break the most important rule in programming, readability.

...and you'll soon (GWT 2.3 ?) be able to use a setConstraintViolations() on the SimpleBeanEditorDriver and take advantage of the HasEditorErrors.

That being said, maybe you should extend the AbstractEditorDriverGenerator (or maybe you could extend the SimpleBeanEditorDriverGenerator) to do you own setErrors on a XxxEditorGenerator of your own (or one that extends SimpleBeanEditorDriver)

Thanks Colin for the tip.

Re: Where’s my Java reflection?

Nice - I would suggest looking into the print(String, Object...) overloads on SourceWriter to make your code a little easier to read/write. Additionally, using SourceWriter.indent(), SourceWriter.outdent() and println instead of print can make the generated code easier to read and debug. Line 83 to 87 could look like this:

sourceWriter.println("public void bindErrors(%s errorable, Map<String, List<String>> errors) {", parameterizedType.getQualifiedSourceName());
sourceWriter.indent();
sourceWriter.println("System.out.println(\"Implement it now: \")");
sourceWriter.outdent();
sourceWriter.println("}");

However, the new initialization block defined like this will run after the constructor, not before the constructor as other initialization blocks
