HTTP Connection thread doesn't update result inside TimerTask - BlackBerry Java -

i'm doing http call ksoap within timertask can update data every 5 minutes. after getting data web service provide them interface via function procecssdata(). works out first time, although timer firing every time data stays same. in fact, ui being drawn every 5 minutes uses data first http call. have idea why might happen? seems me variables inside httpcall() function not being updated.

public class connectionthread extends thread {  soapobject request; soapobject result; soapserializationenvelope envelope;  string[][] resultarray; int resultlength;  public connectionthread(connectioncallback concallback) {      callbackobj = concallback;      refreshtask = new timertask() {         public void run() {             httpcall();         }     };      new timer().schedule(refreshtask, 0, 50000); }  public void httpcall() {      request = new soapobject(servicenamespace, methodname);     result = null;      envelope = new soapserializationenvelope(soapenvelope.ver11);     envelope.setoutputsoapobject(request);      http = new httptransport(serviceurl);      try {         http.call(soapaction, envelope);         result = (soapobject) envelope.getresponse();         resultlength = result.getpropertycount();     } catch (final interruptedioexception ex) {         dialog.alert("no internet connection!");         _isconnected = false;     }     // other catch blocks     {         http.reset();     }      resultarray = new string[resultlength][resultlength * 8];     // put result own stringarray      if (_isconnected) {         callbackobj.processdata(resultarray, resultlength);     } } } 

any soo appreciated! :) cheers, musipoo

in first place i'd advise not extend thread unless need override custom threading behavior (that not case , scary thing do). instead, the recommended approach implement runnable , pass thread constructor. in javase have introduced new executors framework gets rid of instantiating threads old way. timers it's similar here implement timertask pretty runnable (inherits it), , schedule it.

another issue code starts thread within constructor, dangerous thing do, because every new instance created spawn new thread (the 1 asociated timer). considered antipattern. never this, , if do, please document , make sure using class know it. (more info here). confusing class extending thread launches timer in constructor, , doesn't override run (what inheritance for?).

these tips make code clearer , bit safer, won't fix problem. think problem might in updating result variable not putting resultarray (or maybe ommited code?).
