[RestAPI] create a new Restlet

Hi,

I try to create a new restlet in the last release of Nuxeo.
For that, I use a plugin.
First, I wrote my class (TestClass, name testClass) with the UploadRestlet model.
Second, I wrote the restlets-contrib.xml file (in the ressources/OSGI-INF directory):

<?xml version="1.0"?> 
<component name="org.nuxeo.ecm.platform.ui.web.restAPI.contrib"> 

        <extension 
        target="org.nuxeo.ecm.platform.ui.web.restAPI.service.PluggableRestletService" 
                point="restlets"> 
                <restletPlugin 
                		name="testClass" 
                        class="com.package.TestClass" 
                        enabled="true" 
                        useSeam="true"
                        useConversation="true"> 
                        <urlPatterns> 
                                <urlPattern> 
                                        /testClass
                                </urlPattern> 
                        </urlPatterns> 
                </restletPlugin> 
        </extension> 
</component> 

I've deployed my plugin and tried the following URL:
http://localhost:8080/nuxeo/restAPI/testClass

but it does not work.
If someone could help me...

I hope that someone will read this message because this forum seems to be inactive....

Thanks in advance,
Regards,
Xavier.
