java - JSON Parsing Exception: Failed to decode VALUE_STRING as base64 (MIME-NO-LINEFEEDS): Illegal character '"' (code 0x22) in base64 content -

using jackson , i'm trying encode data in json & it's giving exception.

i tried string data & byte[] data:

string representation of same data here: bytes converted string-------->> {  "appname": "aaa",  "devicetype": "diehdcj",  "reporteddate": "2015-05-03t15:38:45+00:00",  "sessionid": "5366372183482-6736-23562378",  "deviceid": "2151272389",  "commandname" : "wqgduwusdue",  "protocolversion" : "0.1",  "protocolname" : "whjs_ashk_ask",  "data" : "false" } 

java

16:50:46.065 [] [] error aaatshconnector [http-apr-10.40.120.85-80-exec-3] - json parsing exception: failed decode value_string base64 (mime-no-linefeeds): illegal character '"' (code 0x22) in base64 content

here's code parsing:

java

@consumes(mediatype.application_json) @produces(mediatype.application_json) public response retrievedevicepassword(inputstream request, @context httpservletrequest servletrequest) throws badrequestexception, validationexception, unknownserverexception {     objectmapper objectmapper = new objectmapper();     demorequest req = null;     demorequest res = null;     byte[] data = null;     data= ioutils.tobytearray(request);     demorequest = objectmapper.readvalue(data, demorequest.class); //it's exception occurs 

java

//snippet of pojo @xmlrootelement(name = "demorequest")  @jsoninclude(include.non_empty)  public class demorequest {   private string commandname;  private string sessionid;  private byte[] data;  //getters & setters   } 

amazingly when try convert same string or byte[] little change in actual content "data" : "true" , works.

can please help

found solution, don't know what's doing: if place escape character in front of false, "data" : "\false" , works fine.

what explanation that?

json parsing exception: failed decode value_string base64 (mime-no-linefeeds): illegal character '"' (code 0x22) in base64 content

the above exception comes in when property of type byte[] , json content represented in string. jackson thinks in case json data represented base64 encoded , tries decode byte[]. if string present in data field isn't encoded base64 string, jackson raises above exception.
