Using ToCollege with GWT 2.0
Maurice Nee
I've been trying to go through the Building ToCollege.net appendix and
have run into many problems. I have downloaded the project from GitHub
and have imported it into Eclipse. I'm running OS X 10.6 (Snow
Leopard). I have installed the SpringSource Tools Suite, Maven2,
m2eclipse, Hibernate Tools, the GWT Plugin for Eclipse, Subclipse, and
MySQL. I'm running Eclipse Galileo J2EE. I'm starting to get a little
frustrated as I've been looking for resources on how to setup a
project that uses GWT 2.0 and Hibernate3 for over a week now. I was
extremely happy to find this book, as my problems are mostly concerned
with how to SETUP a working project that utilizes all of these
technologies, which seems to be a focus of this book. I have a descent
understanding of how these tools work individually, but have a serious
lack of understanding of how to get them to work together. So I got
Jeff's book, with some renewed hopes, only to find that after
importing the project, I am greeted with 33 errors. I am not trying to
whine as I understand how volatile all these technologies are and that
a lot of things have changed since the time when Jeff's book was
published. However, it's very difficult to fix errors related to the
project's structure and configuration when that's the very thing I set
out to learn about via this book. Again, excuse me for venting, I'm
still in the hair pulling days of learning these frameworks. Below are
the errors Im receiving.
I guessing that the 6 Maven errors I'm receiving have to do with
the .jars that need to be manually installed. However, I have already
run the following:
cd Setup/maven
chmod a+x install*
./install-all
./run_jetty_gwt

It looks to me like:
The container 'Maven Dependencies' references non existing library '/
Users/mauricenee/.m2/repository/com/google/gwt-user/1.5.0-M1/gwt-
user-1.5.0-M1.jar'
is the first error I'd look at. Have you followed the directions at
http://code.google.com/p/tocollege-net/wiki/GettingStarted
to install 1.5.3?

Thanks so much for getting back to me! Really appreciate it!
I'd like to use GWT 2.0 for my own project so I was hoping I could
integrate it with ToCollege. So far, I've replaced some of the GWT
dependencies with the following in my POM:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.0.3</version>
</dependency>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-dev</artifactId>
<version>2.0.3</version>
</dependency>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-servlet</artifactId>
<version>2.0.3</version>
</dependency>
<dependency>
<groupId>com.google.gwt.google-apis</groupId>
<artifactId>gwt-gears</artifactId>
<version>1.2.1</version>
</dependency>
I had to change some of the group ids. I also removed the ${gwt-dev}
property from the gwt-dev dependency. The latest version of the gwt-
dev-mac.jar or any other OS specific gwt-dev jar I could find was:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-dev-mac</artifactId>
<version>2.0.0-6320</version>
</dependency>
However, this jar is not hosted in the central repository, but rather
in the JBoss repository. Also, in the Getting Started directions, you
mention that the GWT jars in the Maven repository do not include OS
specific libraries. I've extracted the gwt-dev jar for version 2.0.3
in an attempt to see if those libraries are now included but there are
a ton of files and I wasn't sure where to look. So, I downloaded both
the GWT 1.5.3 SDK and the GWT 2.0.3 SDK to compare them. My download
of GWT 1.5.3 included the gwt-dev-mac.jar and several .jnilib files.
Are the .jnilib files the ones you were saying needed to be copied to
~/.m2/repository/com/google/gwt/gwt-dev/1.5.3/?
These files are not present in my download of the GWT 2.0.3 SDK. In
the my GWT 2.0.3 SDK, there is one .dll file for some reason, and the
dev jar is gwt-dev.jar, (not gwt-dev-mac.jar). Any ideas?
Lastly, is Google Gears the only part of The Google API Libraries for
Google Web Toolkit that the project depends on? I ran a search in
three different Maven Repository browsers for artifacts with the group
id of gwt-google-apis and got no results. However, it looks like there
are individual artifacts for each of the libraries in The Google API
Libraries for Google Web Toolkit. Do I need any of these:
Gadgets 1.1 Library
Ajax Search 1.1 Library
Google Maps 1.0 Library
Google Chart Tools (aka Visualizaiton) 1.1 Library
Language 1.1 Library
AjaxLoader 1.1 Library
I'm down to 26 errors now in the ToCollege project, almost all of
which seem to be Spring AOP problems. Do you know what that means?
Here are the remaining errors:
Project 'ProGWT' is missing required source folder: 'src/test/
resources' ProGWT Build path Build Path Problem
The project cannot be built until build path errors are resolved
ProGWT Unknown Java Problem
Again, thank you so much for your help.
