Getting illegal character range in regex :java -


i have simple regex pattern verifies names. when run illegal character range error. thought escaping "\s" allow space compiler still complaining.

public boolean verifyname(string name) {     string namepattern = "^[\\p{l}]++(?:[',-\\s][\\p{l}]++)*+\\.?$";     return name.matches(namepattern); }

and error think shouldn't occurring since name might contain anny of these [',-\\s]

so not understanding?

you can't have range "from , whitespace". perhaps meant escape -?

\s not space, it's [ \t\r\n\v\f] (space, tab, carriage return, newline, vertical tab or form feed).

things work:

"[ ',-]"  "[',\\- ]"

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!
