java - Null Pointer Exception Calendar.setTime - 


  calendar lasteditdate = calendar.getinstance();                         lasteditdate.settime(rs.getdate("last_edit_date"));                         productgroup.setlasteditdate(lasteditdate);

i've got nullpointerexception:

[error] [16.08.2013 11:30:43] [ databaseworker] = [admin][get product groups] java.lang.nullpointerexception @ java.util.calendar.settime(calendar.java:1106) @ ro.gs.service.catering.dao.productgroupdao$3.dowork(productgroupdao.java:220)

can tell me why have got exception?

getdate(string columnlabel) returns

the column value; if value sql null, value returned null

does table allow nulls in column?

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!
