How to get GWT 2.0 and Restlet 2.0 to play nice
I am having trouble getting Restlet to play nice with GWT in the same project. I have been trying the examples from Restlets website to no avail
I am using Eclipse, Maven2 plugin, GWT, and Restlet GWT. I have never used server side code in this GWT project before and I know there is some custom setup involved. I am deploying locally for the time being using the built in Jetty in GWT Hosted Mode. I can get my front end to display but my back end is not executing.
I did add this to my web.xml file which is from the example (for the time being I am trying to drop the example into my project).
<servlet>
<servlet-name>adapter</servlet-name>
<servlet-class>org.restlet.ext.gwt.GwtShellServletWrapper</servlet-class>
<init-param>
<param-name>org.restlet.application</param-name>
<param-value>org.restlet.example.gwt.server.TestServerApplication</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>adapter</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
I did notice that my web.xml file is located separately from my war deployment directory. My project dir structure is setup as follows.
Project Root
src/main/java
src/main/resources
src/main/test
JRE
Maven Dependecies
GWT SDK
src
main
webapp
WEB-INF
web.xml
target
war
<my project dir>
WEB-INF
lib
pom.xml
So there is no web.xml under my war files WEB-INF directory. I am new to this type of application so it is most likely a matter of me not understanding the directory structure and how my GWT project is compiling into these dirs.

Thanks
It's hard to tell what the problem is exactly without seeing your pom.xml but did you configure the maven-war-plugin as described at the bottom of the Setup Maven for GWT development:
Configuring maven-war-plugin
Google Eclipse Plugin requires your web application to be created as an exploded WAR in /war (hard coded path). To match this requirement, you have two options :
- Move your
src/main/webapp
folder to/war
and configure maven-war-pluginwarSourceDirectory
parameter. This is the inplace setup, as the webapp source will be used to build the exploded WAR layout.- Configure maven-war-plugin to build the webapp in
/war
(webappDirectory
parameter) instead of the standardoutputDirectory
.The gwt-maven-plugin has a boolean inplace parameter to configure the option you choose. The
inplace
mode is interesting if you use JSPs as no build/packaging/deployment is required to see changes made in the JSP file. Same applies to static files like CSS.
Below, a typical configuration of the maven-war-plugin for the inplace setup:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<warSourceDirectory>war</warSourceDirectory>
<webXml>src/main/webapp/WEB-INF/web.xml</webXml>
</configuration>
</plugin>
Tell me if this helps or not (in which case, don't hesitate to clarify what is unclear of what is still causing troubles).
PS: Also maybe have a look at this previous answer.
Well the problem was my web.xml file was located in my src/main/webapp/WEB-INF/web.xml even though my war plugin was configured to get my web.xml file from there it didnt place it in my war/WEB-INF/ folder. To fix it, I manually copied the web.xml file into the war/WEB-INF dir and it worked.
