在 localhost 中启用 jersey 中的 POJOMappingFeature 后从应用引擎运行时出错

Question

Single element in jsonArray was serialized as json object in my code. To solve this I added

<init-param>
          <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
          <param-value>true</param-value>
    </init-param>

This works fine on localhost but gives following error when I deploy it to app engine :

java.lang.NoSuchMethodError: org.codehaus.jackson.map.SerializationConfig.isEnabled(Lorg/codehaus/jackson/map/MapperConfig$ConfigFeature;)Z

Your app engine doesn't supports jersey. It's only Saas based so you need to create App Engine api based resources
