To add a restful service that will be used by all tools, you have to :

• Add in dependencies in your ejb if not already present :

<dependency>	
	<groupId>net.ihe.gazelle.maven</groupId>
	<artifactId>version</artifactId>
	<version>1.0.2</version>
	<type>ejb</type>
</dependency>
<dependency>
	<groupId>org.jboss.resteasy</groupId>
	<artifactId>resteasy-jaxrs</artifactId>
</dependency>
<dependency>
	<groupId>org.jboss.resteasy</groupId>
	<artifactId>resteasy-jaxb-provider</artifactId>
</dependency>
<dependency>
	<groupId>org.jboss.seam</groupId>
	<artifactId>jboss-seam-resteasy</artifactId>
</dependency>
<dependency>
	<groupId>org.scannotation</groupId>
	<artifactId>scannotation</artifactId>
	<version>1.0.2</version>
</dependency> 

• Create file in ejb/src/main/resources/gzl.version.properties with content :

buildVersion=${build.version}

• Finally you have to add in the web.xml  :

<!-- Resteasy -->
	<context-param>
		<param-name>resteasy.jndi.resources</param-name>
		<param-value>gazelle-proxy/VersionProvider/local</param-value>
		<!--If you need to declare more than one resource, separate them by comas -->
	</context-param>
	<!-- The following lines are required only if you decide not to use the application base path as base URI for your REST services -->
	<context-param>
		<param-name>resteasy.servlet.mapping.prefix</param-name>
		<param-value>/rest</param-value>
	</context-param>
	<!-- end of optional lines -->
	<listener>
		<listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
	</listener>
	<servlet>
		<servlet-name>Resteasy</servlet-name>
		<servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>Resteasy</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>
