java - "SocketException: Unexpected end of file from server" from servlet but not from standalone application -

-

i call servlet servlet. can call remote servlet standalone application cannot call servlet (it on glassfish). use same code call (i error @ last code line):

url serveraddress = new url(endpoint); //set initial connection httpurlconnection connection = (httpurlconnection) serveraddress.openconnection(); connection.setrequestmethod("post"); connection.setdooutput(true); connection.setdoinput(true); connection.setreadtimeout(timeout); connection.setrequestproperty("content-type", "text/xml; charset=iso-8859-1"); connection.connect(); outputstreamwriter wr = new outputstreamwriter(connection.getoutputstream()); wr.write(requestbody); wr.flush(); bufferedreader rd = new bufferedreader(new inputstreamreader(connection.getinputstream()));

it suspicious code can't read response of remote servlet servlet doesn't reply @ all. why reply when call standlone app? don't understand... got exception:

java.net.socketexception: unexpected end of file server     @ sun.net.www.http.httpclient.parsehttpheader(httpclient.java:769)     @ sun.net.www.http.httpclient.parsehttp(httpclient.java:632)     @ sun.net.www.http.httpclient.parsehttpheader(httpclient.java:766)     @ sun.net.www.http.httpclient.parsehttp(httpclient.java:632)     @ sun.net.www.protocol.http.httpurlconnection.getinputstream(httpurlconnection.java:1049)

has idea? possible there restricitions servlets not use httpurlconnection? thanks!

this might happening because content-length header not set. , because end of post request body not sent. server ending waiting till timeout end of stream.

you should try out these 2 things working:

  • set content length header request body size before doing connect()
  • try closing connection.getoutputstream().close() send end of post request.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
