Struts2 @Inject doesn't work in Jersey. Other web services

I have created an application to test struts2 ( @Inject

) dependency injection . Injection works fine in many areas, apart from the jersey service class, in which I defined the web service actions.

I am getting an exception like below

Sep 22, 2014 8:48:50 AM com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException
SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container
java.lang.NullPointerException
    at usermodules.services.UserModulesServices.userName(UserModulesServices.java:30)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

      

        
        
        
      

    

Can someone tell me some solution for this

struts2.xml
