Problem when deploying my gwt project under tomcat

[zizou84]

Hi
I am using gwt 2.1.0 with gwt-sl 1.1 (maven project)
In developpment mode,my application works fine
but the problem when i tested my application under tomcat,i got 404
error
I am using maven-war-plugin to generate the war directory which i
copied under TOMCAT_HOME\webapps
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<warSourceDirectory>war</warSourceDirectory>
<webXml>src/main/webapp/WEB-INF/web.xml</webXml>
</configuration>
</plugin>

The "war" directory generates looks fine,why my project isn't running
under tomcat?
Thanks
