Это мой web.xml:

<display-name>GoogleMapLoadingTest</display-name> 
<servlet> 
    <servlet-name>Jersey REST Services</servlet-name> 
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> 
    <init-param> 
     <param-name>com.sun.jersey.config.property.packages</param-name> 
     <param-value>com.hastha.maperp.webservice</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 
<servlet-mapping> 
    <servlet-name>Jersey REST Services</servlet-name> 
    <url-pattern>/*</url-pattern> 
</servlet-mapping>

ОБНОВЛЕНИЕ:

Добавление класса приложения не имеет эффекта:

public class MapErpApplication extends Application { 

public Set<Class<?>> getClasses() 
{ 
    Set<Class<?>> res=new HashSet<Class<?>>(); 
    res.add(MapErpService.class); 
    res.add(MapErpGetService.class); 
    return res; 
} 
}

Я все еще получаю эту ошибку:
