hibernate - Order second table before joining -


i have topicentity contains many postentity. each postentity belongs 1 topicentity. need sort topics last post creation date, creationdate property of newest post in topic.

what think needs happen:

  1. get topics
  2. join posts belong topic
  3. sort posts creation date
  4. get newest post each topic , use date sort topics

this have currently:

this.session.createcriteria(topicentity.class, "topic")     .createalias("topic.posts", "post", criteriaspecification.left_join)     .addorder(order.asc("post.creationdate")).list();

this not sort topics in way. believe because not perform points 3 , 4 list.

anyway, hint me proper way of achieving desired result? prefer criteria, if hql required, that's fine.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
