is possible to combine: jersey + jetty + spring

Question

I'm trying to create a webserver embedding jetty (rather than Java EE) , and map my servlets RESTfully, using jersey.
I'm using spring for dependency injection, and mapping the servlets as beans However, when I try to make an HTTP req to the mapped servlets, i get error 500- server error, or 404, page not found.
I'm not sure if i'm doing this the right way, and I should probably be using the jetty.xml rather than this. (wondering if there's a shorcut using jetty.xml)

I have one class in the servlets package: DoNothing.java

package servlets;

import javax.ws.rs.GET;

import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/nothing")
public class doNothing
{
    @GET
    @Produces("text/plain")
    public String returnNothing()
    {
        return ("test");
    }


}

what in the world am I doing wrong? or should I ask what in the world am I doing right?

Thanks

I was looking for a way to use Jersey+Spring+Embedded Jetty and found this question. I tried your method and it actually works.

If you want to actually use Spring beans in your resources you can use jersey-spring:

<bean id="server" class="org.mortbay.jetty.Server" destroy-method="stop">
    <property name="connectors">
        <list>
            <bean id="Connector" class="org.mortbay.jetty.nio.SelectChannelConnector">
                 <property name="port" value="8080"/>
            </bean>
        </list>
    </property>
    <property name="handlers">
        <list>
            <bean class="org.mortbay.jetty.servlet.Context">
                <property name="contextPath" value="/"/>
                <property name="sessionHandler">
                    <bean class="org.mortbay.jetty.servlet.SessionHandler" />
                </property>
                <property name="servletHandler">
                    <bean class="org.mortbay.jetty.servlet.ServletHandler">
                        <property name="servlets">
                            <list>
                                <bean class="org.mortbay.jetty.servlet.ServletHolder">
                                    <property name="name" value="jersey" />
                                    <property name="servlet">

                                        <entry key="com.sun.jersey.spi.container.ContainerResponseFilters"

                                    </map>
                                    </property>

                                </bean>
                            </list>

                <property name="eventListeners">

                        <entry key="contextConfigLocation" value="classpath:META-INF/AdditionalBeansContext.xml"/>
                    </map>
                </property>
            </bean><!--
        --></list>
    </property>
</bean>

In file AdditionalBeansContext.xml:

Then define your Resources with: @Component annotation, injected beans with @Autowired
