To remedy this use the following steps:

1. Make the webapp directory the same as the output for your gwt code.

   ...
   <plugin>
   	<groupId>org.apache.maven.plugins</groupId>
   	<artifactId>maven-war-plugin</artifactId>
   	<configuration>
   		<webappDirectory>${project.build.directory}/${project.build.finalName}/my.long.package.name.Application	</webappDirectory>
   	</configuration>
   </plugin>
   ...

2. Ensure that your rpc servlets don’t have the package as a prefix.

   ...
   <plugin>
   	<groupId>com.totsp.gwt</groupId>
   	<artifactId>maven-googlewebtoolkit2-plugin</artifactId>
   	...
   	<configuration>
   		...
   		<webXmlServletPathAsIs>true</webXmlServletPathAsIs>
   	</configuration>
   	...
   </plugin>
   ...

3. Change your index.html file to point to your app.
   From:

   <meta http-equiv="REFRESH" content="0;url=my.long.package.name.Application/Application.html">

   To:

   <meta http-equiv="REFRESH" content="0;url=Application.html">

4. Your done.

If you’re using the maven build system then just alter your pom to have:

<build>
	<finalName>ROOT</finalName>
	...
</build>

Simple when you know how…

I did plenty of reading (Maven: The Definitive Guide is a good place to start), but nowhere did I find an easy step-by-step quickstart for this combination of tools.

So I’ve pieced my reading and research together and here it is:

Prerequisites

Java
maven 2
eclipse 3.4.1

Create a new skeleton project:

1
2
3
4
5
6

cd ~/workspace/</br>
mvn archetype:generate -DgroupId={name of your group e.g. com.austenconstable} \
-DartifactId={name of your app} \
-DarchetypeGroupId=org.apache.struts \
-DarchetypeArtifactId=struts2-archetype-starter \
-DarchetypeVersion=2.0.11.2

If you’re not sure on the latest struts 2 archetype release version check here.

Generate the eclipse project files:

mvn eclipse:eclipse

Configure eclipse:

mvn eclipse:configure-workspace -Declipse.workspace=/path/to/your/workspace/

Import the project into eclipse:

Fire up eclipse and use File>Import…

And now all you need to do is build your app!
