Recientemente agregué jersey a mi proyecto de aplicación de motor, todo funciona muy bien en mi máquina local, pero cuando intento acceder a la página en el sitio desplegado obtengo errores. Creo que podría incluir una clase no compatible, pero no creo que esté usando ninguna. La mayor parte de mi código es una copia exacta de esta guía para configurarjQuery subir

Aquí está mi código:

@GET
@Path("/url")
public Response getCallbackUrl() {
  /* this is /_ah/upload and it redirects to its given path */
  String url = blobstoreService.createUploadUrl("/rest/file");
  return Response.ok(new FileUrl(url), MediaType.APPLICATION_JSON).build();
}

web.xml:

<servlet>
    <servlet-name>jersey</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.thedailycaption</param-value>
    </init-param>
    <init-param>
           <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
         <param-value>true</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>jersey</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

Aquí está el error que estoy recibiendo:
