Hy everybody,,,,

i have a connection with http connection on thread...

i want to set specified time to time out, for example i want to force thread and show dialog timeOut information if connection more than 10000ms... so user not wait too long... any body help me?

you can use http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/io/SocketConnectionEnhanced.ht... for direct tcp connections, or ";ConnectionTimeout=30000;deviceside=false" for a MDS connection.
As far as i know other connection types do not support a timeout.

the new connectionfactory encapsulates these into http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/io/transport/ConnectionFactory...

If you use ConnectionFactory, you can set a connection timeout on that.  I have not actually attempted this nor do I know what happens when the time is exceeded, sorry,

Another option is to start your own Timer, and then try to cancel the connection if the Timer returns before the connection is complete.  In this circumstance you can allow the stalling Dialog to continue so the user does not wait and ignore the results of the request if it does eventually come back.  Not exactly stopping it but the effect from a user perspective is the same.

my part connection like this,

connection = (HttpConnection) Connector.open("http://ecc.ft.ugm.ac.id/?r=blackberryapp/vacancybycomp&offset="+offset+connParameters);
		    connection.setRequestMethod(HttpConnection.GET);
		    connection.setRequestProperty(net.rim.device.api.io.http.HttpProtocolConstants.HEADER_CONTENT_TYPE,"application /x-www-form-urlencoded");
		    os = connection.openOutputStream();
		
		      if (connection.getResponseCode() == javax.microedition.io.HttpConnection.HTTP_OK) {
		      is=connection.openInputStream();
		    
		              String xml = "";
		              int ch;

		              while((ch=is.read()) != -1){
		            	  sb.append((char)ch);

		              }
		              xml = sb.toString();

any the best way to set time out on httpconnection...

use ConnectionFactory

[enamur_rashid]

ConnectionFactory doesnt support  setting timeout(BlackBerry API 5.0.0 ) tough it has a default timeout. Custom made timer can be a good idea as peter said. 

[simon_hain]

setConnectionTimeout
public void setConnectionTimeout(long connectionTimeout)
Sets connectionTimeout to the desired value

Parameters:
connectionTimeout - the connectionTimeout to set (in milliseconds)
Since:
BlackBerry API 5.0.0

Ok im have try connection whit connectionFactory... like this

	MyConnectionFactory connect = new MyConnectionFactory();
        			connect.setConnectionTimeout(2000);
        			connect.setTimeLimit(2000);
        			ConnectionDescriptor conDesc = null;
        			try{
        			    conDesc = connect.getConnection("http://192.168.1.26/eccx/?r=blackberryapp/moreindex&id_comp="+x+"&offset="+offset);
        			}catch(Exception e){
        			    System.out.println(e.toString()+":"+e.getMessage());
        			}
        			//String response = "";
        			if(conDesc!=null){
        				try{
        			       connection = (HttpConnection)conDesc.getConnection();
        			       connection.setRequestMethod(HttpConnection.GET);
        			       connection.setRequestProperty("Connection", "close"); // close the connection after success sending request and receiving response from the server
       			           connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
       			           os = connection.openOutputStream();
       	        		
              		  //  os.write(postBytes);
       			           os.flush();
       			           os.close();

       			           if (connection.getResponseCode() == HttpConnection.HTTP_OK) {
       			        	   is=connection.openInputStream();
              		    
              		              String xml = "";
              		              int ch;

              		              while((ch=is.read()) != -1){
              		            	  sb.append((char)ch);

              		              }
              		              xml = sb.toString();
              		
              					jso = new JSONObject(xml); 
       			           }
        			        
        				}catch(Exception e){
        			      //  System.out.println(e.toString()+":"+e.getMessage());
        			        Dialog.alert("error, time-out");
        			    }

 code above is to try if the connection timeout, how to catch the error? and show dialog alert, where i must put the code?
