java ee - Spring equivalent to EJB Singleton Session Bean's concurrency guarantees -


i'm in process of converting java ee 6 application spring + non-ee container (for example jetty) , i'm looking alternative java ee's singleton session bean (usually implemented using @singleton annotation).

the singleton aspect of handled spring. @singleton annotation implies concurrency guarantees: default, methods of singleton session bean strictly serialized write-lock. (the behavior can changed using @lockannotation.)

is there (ideally drop-in) equivalent in spring? @lock customization feature not necessary, i'm looking better alternative manually synchronizing every method of every singleton session bean.

there seems no equivalent in spring. ended using manual synchronization necessary.

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!
