Configuring GWT to use custom web.xml with Ant

[mfuller]

I had a difficult time getting my head around how to use the gwt-sl
library to integrate Spring with GWT. Thanks to George Georgovassilis
and this posthttp://groups.google.com/group/gwt-sl/browse_thread/thread/9133aa02de7f7433/#
I was finally able to get it to work within hosted mode. As the post
mentions it is kind of messy.

I created an Ant build file to do this and launch the shell. Hopefully
someone will find this useful. Note, I use intellij for all my
development which allows me compile, deploy, launch, and test my web
applications, so I use Ant very rarely. So I'm sure an Ant pro can
make the build.xml better.

Here is my build.properties

application.dir=C:/code/simpleGwtSpring/trunk
main.gwt=org.sample.Application
main.html=Application.html
lib.dir=lib
internal.target.dir=www
java.class.dir=classes/production/simpleGwtSpring
javac.source=1.5
javac.target=1.5
gwt.dir=C:/lib/gwt-windows-1.4.10
custom.tomcat.dir=webContent/tomcat

Here is my build.xml
<?xml version="1.0"?>
