Issues Converting String to javax.json.JsonString

Question

I have a class that looks something like this

    private byte[] profilePicture;

    private ProfileType profileType;

    private String profileHandle;

    private String personalEmail;

    private Address address;

To convert this to Json using javax.json is like this:

    JsonObject payloadObject = Json.createObjectBuilder()

    .add("profilePicture", profilePictureEncoded)

    .add("profileType", profileType.ordinal())

    .add("profileHandle", profileHandle)

    .add("personalEmail", personalEmail)

    .add("webAppEmail", webappEmail)

    .add("address", address.produceJsonPayload())

    .build();

All good!! except sometimes there is no profile picture so I wanted to build this incrementally ie

    JsonObject payloadObject = Json.createObjectBuilder().build();

    if(profilePicture != null)

    {

        final String profilePictureEncoded = ..... //encode the image

        payloadObject.put("profilePicture",profilePictureEncoded);

    }

problem is you cant because I can't cast profilePictureEncoded to a JsonString

Has anyone got something like this working? Or do I need to use another Json Library?

You can just get a reference to the JsonObjectBuilder.

JsonObjectBuilder payloadObjectBuilder = Json.createObjectBuilder();

wait until you have everything while constructing

if(profilePicture != null)
{
    final String profilePictureEncoded = ..... //encode the image
    payloadObject.add("profilePicture",profilePictureEncoded);
}

and then build()

JsonObject payloadObject = payloadObjectBuilder.build();
