Reference Project - Ant Build, GWT (1.4), Spring, Hibernate
Jeremy Przasnyski
reference project is getting close to being stable.
Here's a list of features (from the readme.txt):
1) Ant build file (builds, localizes, deploys, runs unit tests,
generates coverage reports, genrates DDL, etc)
2) Eclipse pre-configured project (Googlipse integration currently
broken)
3) GWT support (with Spring IoC for server-side components using
GWT Server Library - http://gwt-widget.sourceforge.net )
4) Spring Inversion of Control for all components
5) Hibernate ORM (using JDK 1.5 annotations)
6) Dozer Bean Mapper (maps Server-side domain objects to client-side
beans)
7) JUnit unit tests (using JDK 1.5 annotated classes, DAO code tested
against H2 DB)
8) Cobertura unit test code coverage & reporting
9) Log4J Logging (plus a logging facade that makes dropping logging
statements into new classes easier -- at least I think so!)
Here's a link to the full readme:

Please make use of this project. Feedback is welcome as well!

Just a quick note. I am running XpPro, the checkout from svn (within
Eclipse 3.3 rc2) was fine, the initial Eclipse build generated the
following errors:
Severity and Description Path Resource Location Creation Time Id
Project 'gwt-ant' is missing required library: 'build/test/gen' gwt-
ant Build path 1180971951750 47437
The project cannot be built until build path errors are resolved gwt-
ant Unknown 1180971951750 47439
Unbound classpath container: 'JRE System Library [JVM 1.5.0 (MacOS X
Default)]' in project 'gwt-ant' gwt-ant Build path 1180971951750
47438
I have yet to run the ant scrip (probably the first error) and I am
running Java 1.6 on windows (the second error)
I just dropped the JRE (MAC OS) reference and added a library
reference (I believe this is the preferred way in Eclipse 3.3) That
single change cleared both problems - I do not know why (but hve
ceased being surprised by software.)
I will not have much time to "play" with this now but will provide
feedback (if things go as I hope.)
Duh, I almost forgot the most important thing - thank you for sharing
this,

Thanks for the head's-up.

You have done some amazing work! This is a parade display of all the
disciplines which
are required to structure and maintain a project properly: it is not
only about coding the
stuff right, but about structuring it, getting the configuration right
andpackaging it.
You thought through many of the things that a GWT developer stumbles
over again
and again. In this respect your projects shows the great value of IoC,
how one can plug
anything as heterogeneous together as two server-agnostic ORM
frameworks like Hibernate
and GWT over a (not-only-)web-framework such as Spring. And I'm glad
that in your massive
configuration the SL takes up only a handful of lines ;-)
Keep up the good work!

Thanks for the kind words. I've been a Java Developer for about 8 years now and been working with some of the best in the business. I attribute my success to good teachers and hard work.
I also applaud the folks at Google for opening something like GWT up to the public. The UI aspect of web applications 'traditionally' has been a royal PITA because of the amalgamation of so many different languages into each page (JSP, HTML, CSS, JavaScript, Tag Library X, Tag Library Y, the internal scripting notation for Library X, the internal scripting notation for Library Y, getting Tag Library X to play nice with Tag Library Y, etc, etc). GWT solves all of this since you just write java code and sometimes call out to JavaScript. It is a HUGE relief to just work with one language & I think some very elegant and powerful applications are going to come out of GWT based projects.
I'll continue to hone the project as time permits. I've already made much progress on my GWT project at work & I'll roll anything I learn in refined form into the reference project in my spare time.
If anyone has any suggestions of things they'd like to see, please feel free to let me know & I'll see what I can do.

I've been working on a better UI in another project (based on the reference project) and will probably roll those UI changes into the reference project at some point. My UI is based on the kitchen sink GWT example. I need to take a look at the licensing of those files because I essentially just yanked the code from several classes and repackaged them.
BTW - I pulled this conversation back into the group as I feel it would be useful for people in the group to see.

i feel like i'm bossing you around. Sorry. I will send you the updated
file in a minute...
