Hi Susmitha,

  can you try returning the Response instance, and setting the ArrayList as
the entity as follows:

@GET
@Path("testimage")
@Produces("image/jpeg")
public Response getTestImage() throws
FileNotFoundException {
                ArrayList<InputStream> is=null;
                ...
                ...
                return
Response.ResponseBuilder.type("image/jpeg").entity(is).build();
}
