Hi,
I am newby for Blackberry. I need some consultation from the experts.

I am using my standard midlet(which i use for Nokia, Motorola and other devices) for Blackberry phones and it is working perfectly. But when i try to connect to the server using HttpConnection it does not connect and throws exceptions. Do i have to add some other code / settings as well and is it possible develop client-server based application using standard midlet or not?

I have tried jar/jad, cod/alx files but still not connect to the server.

Kindly guide me.

Thanks in advance.
Shailesh

You need to do your connections on a non-UI thread to allow the blackberry to prompt the user to allow/disallow the connection.

I've written a getWebData method that you can see at http://www.dowling.me.uk/blog/blackb...ebbitmapfield/

import javax.microedition.io.HttpConnection;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class TestMidlet extends MIDlet implements Runnable,CommandListener
{
private Thread thread;
Display display;
Form frm=new Form("Response");
Command cmd=new Command("Exit",Command.OK,0);
public void startApp ()
{
display=Display.getDisplay(this);
frm.addCommand(cmd);
frm.setCommandListener(this);
display.setCurrent(frm);
try
{
thread = new Thread (this);
thread.start ();
}
catch(Exception e)
{
System.out.println(">>> Exception Caught : " + e.toString ());
}
finally
{
System.out.println("-- startApp() : end -- ");
}
}


public void commandAction(Command c,Displayable d)
{
if(c==cmd){
this.notifyDestroyed();
}
}
public void pauseApp ()
{
}

public void destroyApp (boolean unconditional)
{
}
StringBuffer str=new StringBuffer();
public void run ()
{
try
{
HttpConnection con = (HttpConnection) Connector.open("http://www.google.com");
frm.append("Tryig to Connect..");
InputStream is = con.openInputStream();
frm.append("\n\nNow Connecting..");
int c = 0;
while ((c = is.read()) != -1)
{
str.append((char) c);
}
frm.append("\n\n Connected: "+str);
display.setCurrent(frm);
is.close();
con.close();
}
catch(Exception e)

HI,
Please I guess if you are using JDE 4.2 then you have to download and install the "Blackberry Email Service Simulator" and start the MDS before you attempt to use the HTTP Connection.

IT comes along with JDE 4.3 . Please confirm if that is the issue..

Thanks

Hi shailesh ,
if u r using airtel connection while making httpConnection append parameters to it as :
(HttpConnection)Connector.open(baseURL+";WAPGatewa yIP=202.056.231.117;WAPGatewayAPN=airtelgprs.com") ;

now base url can be anything like ur server URL or "www.google.com"

just try this thing and see if its working.

before that ..are u trying it on device or on the simulator?..if simulator then i think ur wil just have to make proxyEnabled varibale from config file of the MDS true and if on device then just try above method
