GWT CSS URL Problem

I have a CSS stylesheet defined at
projectroot/src/main/webapp/MyStyles.css
In my module's .gwt.xml file I reference this with:
<stylesheet src='MyStyles.css'/>

In dev mode, GWT generates the following CSS URL which results in a
404 not found error:
http://127.0.0.1:8888/module/MyStyles.css
The following URL works (when I try manually):
http://127.0.0.1:8888/MyStyles.css

In production mode, GWT generates the following CSS URL which results
in a 404 not found error:
http://localhost:8080/project/module/MyStyles.css
The following URL works (when I try manually):
http://localhost:8080/project/MyStyles.css

I'm using:

GWT 2.3
Project built with Maven archetype: mvn archetype:generate -
DarchetypeRepository=repo1.maven.org -
DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-
plugin -DarchetypeVersion=2.3.0-1
IntelliJ 10.5.x

What am I doing wrong? How can I resolve this?
