Integrating RequestFactory into an eclipse project

[Spundun]

Hi all,

I'm trying to add RequestFactory and objectify to my existing eclipse
project that uses GPE and GAE.

The page http://code.google.com/webtoolkit/doc/latest/DevGuideRequestFactory.html

has the following instructions in the sectioin titled "wiring"

Add the following jars to your WEB-INF/lib directory:

requestfactory-server.jar
javax/validation/validator-api-1.0.0.GA.jar
A JSR 303 Validator of your choice, such as hibernate-validator


my question is, where do I find the requestfactory-server.jar file?
What do I use as a "validator of my choice" that I can use with GAE
and which is easily gettable?

Also, this process feels very clunky compared to the rest of the GPE
experience, is there any plan to integrate it into GPE?

p.s.: I haven't been able to do anything through maven yet. THe
closest I got was when Run As-> Maven install failed with error "You
must use a 32-bit Java runtime to run GWT Hosted Mode." I'm on mac.

The docs have actually already be updated for GWT 2.4! With GWT 2.3 (and it'll still work with future versions if you need more than just requestfactory on the server-side), you'll use gwt-servlet.jar.

Thanks all for the help,

I ended up doing a tedious comparison of my project with DynaTableRf
sample and copied the hibernate validator and gwt-servlet.jar from
there.

After a very frustrating 5 days, I have a working RequestFactory
setup, now I can focus on actually implementing the server end.

Question:
Part of the problem I faced was Uncaught Exceptions with very
unhelpful stack traces. The errors ended up being things like, I had
an inconsistency in id type between getid and findClazz(id), un-
initialized version field, etc. There were no hints whatsoever on the
console, I did an extremely tedious comparison of my project with
DynaTableRf as I said above to fix this.

I'm wondering if this is because I'm missing a configuration that
would automatically point out this inconsistencies. Or is there any
other approach to hunting the problem? A strategically placed break
point on client/server side?

Again, thanks for the responses.

If you pulled down trunk, you could use the client side requestfactory-apt.jar. That does compile time validation on your objects, so you'd probably be able to get the red squiggilies to tell when you're doing something wrong.

You can also download the JAR from SVN, and you can also run ValidationTool to post-process your classes. See http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation

Ah!! I did that already but turns out I missed "enabling annotation
processing" I thought it must be On globally. Now I feel a lot more
confident that I can pull through the RequestFactory approach.

Thanks all.

Thanks David,

I had already Bookmarked your project. But I decided to first
implement this on my own and *then* compare with your example. That
way I wouldn't follow someone else's example blindly.

Thanks
Spundun.
