I am developing a module where i am using rest service to get data. i am not getting how to store JSON using Jackson and store it which has Queryparam also. Any help is really appreciated as I am new to this.I am trying to do server side filtering in extjs infinte grid which is sending the below request to rest service. when the page load first time, it sends

http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&page=1&start=0&limit=500

when you select filter on name and place, it sends

http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&filter=[{"type":"string","value":"Tom","field":"name"},{"type":"string","value":"London","field":"Location"}]&page=1&start=0&limit=500

I am trying to save this in POJO and then sending this to database to retrieve data. For this on rest side i have written something like this

@Provider
@Path("/rest")
public interface restAccessPoint {
@GET
@Path("/populateGrid")
@Produces({MediaType.APPLICATION_JSON})
public Response getallGridData(FilterJsonToJava filterparam,@QueryParam("page") String page,@QueryParam("start") String start,@QueryParam("limit") String limit);
}

public class FilterJsonToJava {
@JsonProperty(value ="filter")
private List<Filter> data;
.. getter and setter below
}

public class Filter {
@JsonProperty("type")
private String type;
@JsonProperty("value")
private String value;
@JsonProperty("field")
private String field;
...getter and setters below
}

I am getting the below error
