java - SocketTimeoutException after four requests to local bitcoind -

i want connect bitcoind using java. plan use htmlunit , gson. right can complete single request successfully. however, can not more four subsequent requests due sockettimeoutexception being thrown @ fifth request.

i tried:

• waiting between requests. (no effect visible)
• forcing failing http status code e.g. requesting getinfoo instead of getinfo. (i not timeout after 4 failing requests)

any or comment appreciated!

package test;  import com.gargoylesoftware.htmlunit.browserversion; import com.gargoylesoftware.htmlunit.failinghttpstatuscodeexception; import com.gargoylesoftware.htmlunit.httpmethod; import com.gargoylesoftware.htmlunit.webclient; import com.gargoylesoftware.htmlunit.webrequest; import com.google.gson.gson; import java.io.ioexception; import java.net.sockettimeoutexception; import java.net.url;  public class test {      public static void main(string[] args) {          webclient client = new webclient(browserversion.firefox_24);          // http://[bitcoind-user]:[password]@localhost:[bitcoind-port]         string baseurl = "http://admin:admin@localhost:8332/";          client.getoptions().settimeout(2000);         while (true) {             try {                 webrequest req = new webrequest(new url(baseurl));                 req.setadditionalheader("content-type", "application/json");                 req.sethttpmethod(httpmethod.post);                  jsonrequestbody body = new jsonrequestbody();                 body.setmethod("getinfo");                 req.setrequestbody(new gson().tojson(body, jsonrequestbody.class));                  client.getpage(req);                 client.closeallwindows();                  system.out.println("ok. (no exception)");              } catch (sockettimeoutexception tex) {                 system.out.println("not ok: sockettimeoutexception");             } catch (ioexception ex) {                 system.out.println("not ok: ioexception");             } catch (failinghttpstatuscodeexception hex) {                 system.out.println("not ok: failinghttpstatuscodeexception");             }         }     } } 

(edit:)

removing .settimeout(2000) did not well. measuring time each request shows quite quick:

ok. (no exception)             timer:  1.161 seconds ok. (no exception)             timer:  0.112 seconds ok. (no exception)             timer:  0.115 seconds ok. (no exception)             timer:  0.075 seconds not ok: sockettimeoutexception timer: 90.119 seconds not ok: sockettimeoutexception timer: 90.145 seconds not ok: sockettimeoutexception timer: 90.134 seconds 

repeating same request multiple times in terminal using curl took less 1 second bitcoind should not causing problems.

firstly, try removing line:

client.getoptions().settimeout(2000); 

if client takes 2 or more seconds process fifth request fail timeout exception.

secondly, make sure disable javascript if don't need it, can take more 2 seconds process too.
