Hello,

I am a BB app. developer. i created an application to work on my BlackBerry 8100.
I use JDE 4.0.2 . I have created one button on screen. When i click that button HTTP request is send to corresponding URL("https://xxx.xxx.xxx") Then I never get the response from the sever. I run my app. in JDE simulator is not connecting the internet . Its take some of time to run my app. after that i get the timeout message '120000' What can i do ...

I tried my application some possible way
1)thro' TCP and WAp, but not works as my service provider is hesitating to give the APN username, password, WAPGatewayIP

My last try is ....

try {
HttpConnection httpConnection = (HttpConnection)Connector.open("https://xxx.xxx.xxx");
httpConnection.setRequestMethod(HttpConnection.POS T);

InputStream inputStream = httpConnection.openInputStream();

int len = (int)httpConnection.getLength();
if (len > 0) {
byte[] data = new byte[len];
int actual = inputStream.read(data);
//process(data);
}
else {
int ch;
while ((ch = inputStream.read()) != -1) {
//process((byte)ch);
}
}

}
catch(IOException e) {
Dialog.alert(e.toString());
}

execution stops at
inputStream.read(data)

Please tell me a solution.

Thanks!!!

Are you also running the MDS simulator? Without it you can't access the internet from the Blackberry.

paramasivan · 07-24-2008, 10:49 AM

As i am using JDE4.0.2, it accompanies a MDS simulator. Before excecuting my application in device simulator, i run the MDS simulator and the command prompt window says at last......
<2008-07-24 21:14:57.812 IST>:[31]:<MDS_MDS>:<DEBUG>:<LAYER = MDS, Web Server Started>

But after running my application into device simulator, i can see no change on the command prompt of MDS simulaotor.

Please let me know, if you need any further details.

And advice me on this. And i am unable to use TCP, WAP methods.

So i can use only the MDS method.

I hope you would help me on this.

Thanks indeed for your quick reply.

Then it would seem that either the PC/MDS server can't look up the host name xxx.xxx.xxx or it can't connect to it once it has the IP address. Things to try:

Use your PC browser to browse to https://xxx.xxx.xxx

If that works, use the browser on the simulator to browse to https://xxx.xxx.xxx

If that works, then have a look at the logs on the web server.

If neither works, try again but replacing the host name with the IP address of the server. If this doesn't work, ie you can't connect to the server from your PC you need to sort that out before the simulator can have a hope.

paramasivan · 07-24-2008, 02:37 PM

The url works fine in my PC.

And i am not testing this in my device simulator as it pops up an error "Could not find service book entry"

My device 8100 have enterprise service activated. So i tried on that.

The execution(at inputStream.read(data)) ends with an uncaught exception "The applcation connection example is is not responding. Process terminated."

Please let me know, how can i fix this.

Many thanks indeed for your reply.

I have a program that reads information from the World of Warcraft Armory. Below is my connection thread. Maybe it'll help some.

Code:

class ServerConnection extends Thread {

        // Declare variables
        HttpConnection http = null;

May i know the sample arguments for the below constructor
public ServerConnection(String character, String server, boolean mds, WowArmoryScreen screen)

Thanks!!!

The arguments are passed from the main screen. They are pulled from fields on the screen. Here's the full code:

Hi!

One thing to keep in mind: HTTP connections should be encapsulated in a thread separate from the main event thread. Because network connectivity and activity and stuff takes a "relatively-significant" amount of time to process, certain networking calls will "block" (halt until data comes in, among other things), which means the OS is prevented from performing other device-event-based tasks/operations. Which the OS can get persnickety about. If the HTTP-connection/transmission/reception code is in a separate thread, it can go off into la-la-land and the OS isn't going to care. That may be why your uncaught exception error.

Other things to think about:

1. It's probably trivial, but you're usually better off compiling and building your BB app with a JDE version that is similar to the device OS version. Keep that in mind. So if your device is OS 4.0.2 (I'm assuming this is a mistype, because the 8100 shipped when OS 4.1 was latest-and-greatest), you would want to use JDE 4.0 or 4.1 - if your device is OS 4.2, you would want to use JDE 4.1 or 4.2 or 4.3.

2. The MDS simulator acts as a "gateway" between the device simulators and the network that the PC is connected to. If you're at home using a broadband internet connection, and you're not doing anything really interesting with your firewall/router, the MDS is probably good to go and should just act as a router for your device simulator. But if you're behind a corporate firewall and/or a proxy, your MDS will need to be configured to deal with that. As hrbuckley mentioned, try to connect to something, even "yahoo.com", using the browser on the simulator with the MDS running (just to be safe, launch the MDS simulator first, wait until it's settled down, then launch the device simulator). The simulator browser should display the yahoo page, AND you should see lots of print output on the command-line screen governing the MDS activity. If you don't get the yahoo page on the simulator browser, or if there's no activity on the MDS command-line screen, something is misbehaving. There's a file called "rimpublic.property" in the MDS config directory - it contains settings that the MDS simulator uses to find the network gateway and any proxy information that's needed to make HTTP connections (my employer requires every HTTP connection to go through a proxy server, and we had to configure MDS simulator to know about this, otherwise nothing would get through).

Good luck!

Cheers,

karl

}

The above code works perfectly for me in simulator, but not in my 8100.
Simula

When i run this in device, it gives me an error saying "Bad DNS Address"
with checking the "Use MDS" box, it gives me an error saying "Invalid URL parameter"

Please let me know, what i should do to fix this.

Many thanks buddy!!!

Paramasivan,
did you get your code work? I see the same problem with my BB Bold.
The Connector.open(url) time out doesn't happen in the simulator,only on the hand held device. I tried deviceside=true and deviceside=false but no help.
I have the APN also set, I guess correctly.

I use JDE 4.0.2 . I have created one button on screen. When i click that button HTTP request is send to corresponding URL("https://xxx.xxx.xxx") Then I never get the response from the sever. I run my app. in JDE simulator is not connecting the internet . Its take some of time to run my app. after that i get the timeout message '120000' What can i do ...

I tried my application some possible way
1)thro' TCP and WAp, but not works as my service provider is hesitating to give the APN username, password, WAPGatewayIP

My last try is ....

try {
HttpConnection httpConnection = (HttpConnection)Connector.open("https://xxx.xxx.xxx");
httpConnection.setRequestMethod(HttpConnection.POS T);

InputStream inputStream = httpConnection.openInputStream();

int len = (int)httpConnection.getLength();
if (len > 0) {

//process((byte)ch);

}
catch(IOException e) {
Dialog.alert(e.toString());
}

execution stops at
inputStream.read(data)

Please tell me a solution.

Thanks!!!

I wrote an HTTPClient recently that works. As stated previously in this post, make sure that you have the MDS server enabled. Check source code:

Code:

import java.io.InputStream;

import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;

public class HTTPClient {
	public static String getPage(String url) {
		String response = "";

		try {
			StreamConnection s = (StreamConnection)Connector.open(url);

			InputStream input = s.openInputStream();

			byte[] data = new byte[256];
			int len = 0;
			StringBuffer raw = new StringBuffer();

			while( -1 != (len = input.read(data))) {
				raw.append(new String(data, 0, len));
			}

			response = raw.toString();

			input.close();
			s.close();
		} catch(Exception e) { }

		return response;
	}
}

Hi folks,

I am also getting the issue with the same,
I want to confirm that if i am using "Deviceside=false" in my Application, then am i need any signing or business with RIM to do this communication?

Regards,
Nagarajan. K

bemshaswing · 12-30-2008, 06:37 AM

according to the api the httpConnection class with which you would use a String url is not a class that requires signing.

Likely though, if you do almost anything more interesting than accessing data and displaying flat text, you will use a class that requires signing. That requires code signing keys available from RIM for 20$ u.s.
