Want to kill my thread of HTTP connection

Hi all

In my Blackberry application, I have my HTTP thread running on a separate thread. In some cases, I want to kill/destroy this running thread. Any suggestions?

Thank you

Progress until you get http connection data dialog box?

Hello

Can someone help me with the progress dialog box until I get the Http connection data?

I tried using Status.show but how will disappear once I have given. Once I have the data I want to update the user interface. I think it should be the combination of Thread and UiApplication.getApplication.invokelater, but if someone can guide me in the right direction, then it will be a great help.

Dial the two thread simultaneius http

In my application I want a main (UI) Thread and two other thread that runs at the same time, now in both the wire I want HttpConnection appeal, so it is possible for both the thread do HttpCall?

I want to know - is it possible?

Because if one thread calls Http between another thread also do Http call connection so that it will give the error as "Stream already open" because the first thread was opened the stream and before the closing of the first stream son second thread will open the stream, so please help me on this...

Thank you

There is nothing on the Blackberry that will prevent both two threads made http URLs of connections to the same (or other) at the same time.

So the answer to your question is 'Yes it is possible. "

HTTP connection limit

Hello guys '

My application creates the HTTP connection. I want to increase the speed of downloading content to the web server. Content consistes of many unit data. In other words, I need to download 100 unit datas. Now, I use the connection of one for downloading this content (100 unit datas). Its download speed is too slow. I want to be fast.

So, I think that a lot of connections can increase the speed of downloading data.

How many connections for a single application to MAX?

You have another way to increase download speed?

Please share knowledge with me guys.

TNX'

I recently did some tests for a real-time application here performance. Essentially on a GSM GPRS (all we have in the United Kingdom) network without EDGE, I could get about 1 K per second. So with a single connection you should get your lot down in less than 20 seconds.

As I said, I don't think that multiple connections will help you because:

(a) I believe that there is only a single underlying communication method and therefore any package that you use for a connection, it is stealing this package to another connection

(b) I suspect that there is a significant amount of overhead, establishing the connection and latency that involves.

Please let us know how it goes...

Kill a thread does not

Hi all

I have a question about the best way to kill a thread does not. My request has been implemented with two sons:

1 update thread - to extract the values from a web service using JSR 172 created heels
2. view the Thread - to display the retrieved values

Each thread runs in its own period of time - say if ever 60 seconds Update wire passages and the display thread runs every 30 seconds.

The issue I'm having is when the update thread tries to retrieve the data from the web service and for some reason any received no response - the queue of messages is completely blocked and the application ultimately ends.

My solution was to introduce a third thread that would check every 5 seconds if the update thread is still running (I store the status in a singleton class) and if it is to kill this thread. However, it did not really work as once the update thread sends a response to the queue of messages is completely blocked (my explanation - not sure) that he won't let even the kill wire (wire n ° 3) run.

Is there a better way, or is there a way to make sure that the thread to kill and take control of the message queue?

Thanks, I hope that everyone is having a good weekend!

You must use the discussions here. HTTP requests throw exceptions of time-out, but they may not be processed correctly, unless they are in a thread. IIRC, using inokeLater for HTTP requests put on the wire of the main event, which is bad.

ESW-540-8 P, http connection and browsers

Howdy,

Portal: cisco-onplus

VAR: 1913

Client: 5651 (USS Nautilus SSN-571)

Version: with On - 100K 9

ESW540 - 8 p on a network with the default settings. The goal is to connect through proxy http OnPlus http (kubrick) devices management I / F and change the settings.

By the compatibility of the devices for ESW540, I define http (port 80) as a method of connection and allow to "set the headers.

Using a PC connected locally, I checked that I can establish http connection directly (without proxy OnPlus) using IE, firefox, and Safari browsers on multiple platforms (2 win 7 PCs (FF, IE, Safari), 1 iPhone4. () Safari). In all cases, I'm able to establish the http connection to the ESW540 connection - 8 p and perform operations remotely on the device http user interface through the user interface of the browsers.

However, when I try the same when connected remotely through OnPlus, I get different behaviors for success/failure in the browser I use.

When I use Firefox or IE, as soon as I click on the 'Connect' button on the modal system, a browser window is launched as planned.

For IE (IE7) on both Win7 computers, 10 seconds after the launch of the window, the device UI presents its login screen. I provide credentials for the connection. Soon after, a partial rendering of the page main 'status' for the device is presented on the user interface of the browser. I can see the CSS styles of painting, but I see no text, areno visible URL and the simulation planned device indicator is not visible. Clearly, the appliance http server enabled connection. Shortly after the connection information has been presented, a dialog box appears that States "disconnected from server...". "xlx...

For firefox (FF 6.02) on the two WIn7PCs, I get the same behavior with one exception - the connection process does not have the point of view of the page for the device UI http authentication.

Note, I am able to navigate, to connect to and manipulate all the pages of the user interface http to a cable modem TWC ODM built... using any platform and one of the three browsers.

Also of note, I have configured the ESW540 - 8 p to the backup configuration file automatically and every night. This automatic access (using the credentials provided in the "References" of the modal device tab) works very well... even if she does not resemble his support in the list of devices.

I suspect that it is a FF/IE browser config issues with specific pains of Kubrick (Java?). But I'm just guessing. Fortunately, I have Safari on all three devices, so this isn't a big deal. Ideallly, however, I prefer using FF - manage my browser of choice for all the other things-webby.

Any help appreciated.

See you soon,.

Dave

PS - I told you lately how 'killer' this "Cisco OnPlus" remote service is? It is beautiful thing you've built.

Captain Howdy!

The ESW540 was a little 'fun' with cross-launch. We expect a potential MR later this fall that may be able to answer some of these questions. In the meantime, I'll get the documentation updated to reflect the following details on ESW540 support.

1. the port 80 and "Headers of difficulty" are correct configuration items to set for cross-launch.

2. the Safari browser works fine, but you have to ignore the pop-up "lost connection". Everything works perfectly.

3 Firefox has a particular problem. When you connect first with firefox, you'll get an error. It is different with different versions of firefox. If you copy the URL and open a new window, and then paste the URL into the new window, things will work (again, with the message lost connection to ignore).

4 IE tends to work perfectly, without any problem. I have only tested with IE8. There could be a problem with IE7.

These problems come from the fact that OnPlus was not there when the ESW has been developed and switches don't usually do the test to be able to withstand to be connected through a firewall. New SMB devices are tested with OnPlus in order to avoid this type of problem in the future.

Specifically, there is a behavior of Web Management page in the ESW trys to be compatible with all web browsers and it breaks down when you launch into another page, or by an indirect method.

Enjoy,

Robert

PS I'm glad you like it. Your praise seems strangely familiar though ;-)

HTTP connectivity from a device problem

Hello

I'm working on an application that works with our web server via HTTP and HTTPS.

As it is a consumer application, we want to operate without MDS, out-of-the-box when a smartphone is purchased at retail with a web access data plan.

I assumed that this means using direct TCP when a Wi - Fi connection is not available.

The following code snippet prepares the URL according to the configuration, and opens the connection:

String fullUrl = (isSecure? ("https://": "http://") + appConfig.getServerHost () + "/" + url + (bbAppState.isWiFiOnly ()? « ; (interface = wifi': "") + (bbAppState.isDeviceSide ()? « ; (deviceside = true': ' ");

c = (HttpConnection) Connector.open (fullUrl, Connector.READ_WRITE, true);

Details of equipment and network:

Feature: 8320
OS 4.5.0.81
T-Mobile US network
Have a data plan (unlimited web and 400 messages)
Connection preference: Wi - Fi preferred
No apn is not specified
Browser and third-party applications downloaded from the App World can access internet via Wi - Fi and EDGE/GPRS with the above parameters

Tried:
1. Free Wi - Fi and EDGE: deviceside = true - get "Tunnel failed '.
2. Free Wi - Fi and EDGE: no deviceside, only the url - get "Tunnel failed '.
3. No deviceside, only = wifi interface - works with a Wi-Fi connection, reports "The Tunnel failed" when out of range of a Wi - Fi connection.
4. I tried parameter APN to internet2.voicestream.com just to test - got the same error 'Tunnel failed '. I would not use it as the browser and other applications need and work when the APN is empty.
My question is if I'm something wrong or missing something. My hypothesis is that third-party apps and BlackBerry Internet Service browser. Is there a way to know? Is there a way to disable it (for example to make sure that the browser and other applications use it)? Our company has recently become a partner of Alliance of BlackBerry, so we can apply to BlackBerry Internet Service, but I do not understand if this is necessary for consumer applications, or if the consumer applications should rely on direct TCP.

Any help will be greatly appreciated.

Thank you

Sergey

Use '; deviceside = true ', you must also specify the details of the AFN, the options of the device or in the string you provide with "; deviceside = true '. If you do not, you will get "Tunnel failed '.

I would like to confirm the settings for T-Mobile APN - the value that you used does not match what I found in a google search.

Browser and other applications will use WAP 2.0 or BIS - B, requiring no configuration. You can use WAP 2.0 - standard article for more details:

Hi all

I use version eclipse3.4 for Blackberry development. In my application, I need to extract data from a Web service via a servlet created by me. I've implemented it using a wire and it works fine.

But the problem is, after the http connection, when control passes to servlet I can't minimize my application using events end key as a normal application. This fine event key only works when the control back on the side of the unit... My entire application got stuck when he tries to retrieve the data from webservice... Please help me on this.

Please guide me how to implement the reduction feature in my application when it attempts to retrieve data from the server using the http connection.

I used this package for connecting

javax.microedition.io.Connector; javax.microedition.io.HttpConnection;

Problems with HTTP connections in 7.0

Hi all

HTTP connections in my work of fine application with 5.0 and 6.0, but they do not work with 7.0. Enough actually, they work with 7.0 when the device is connected with WiFi, but not with 3G (Sprint) mobile network. Connections are also running smoothly on the Simulator. When the application tries to perform an HTTP request, it seems to open the connection, but the connection hangs just until it expires in a minute later.

I'm unable to debug applications with the SDK 6.0 and 7.0 in Eclipse. The debug mode is always suspended my environment.

Can someone speculate as to why this might be the case? For added convenience, my code is below:

    private RequestResults screen;
    private String url;

        this.method = method;
        this.screen = screen;
    }

    private void connection() {

                    + ConnectionParams.getConnection());
            conn.setRequestMethod(method);

            int responseCode = conn.getResponseCode();

            // Check for both 200 AND 201
            if (responseCode != 200 && responseCode != 201) {

                loader.stop();

        return null;

The culprit seems to be adding the line

for my URL when you set the connection settings:

if (record != null && (coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
// Have network coverage and a WAP 2.0 service book record
    connectionParameters = ";ConnectionTimeout=10000;deviceside=true;ConnectionUID="

Wire Vs sleep Vs MDS Http connection Question

Hello

Here's my situation...

I created a thread for background based on this article:

http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800660/How_To _...

Here is my code:

/ * Thread that runs in the background * /.
the final private class BackGroundThread extends Thread {}
private static final int TIMER = 15; minutes
Private boolean _stop = false;

public synchronized void stop() {}
_stop = true;
}

Private boolean isCoverageSufficient() {}
If ((DeviceInfo.isSimulator ()) |)
(RadioInfo.getState ()! = RadioInfo.STATE_OFF & (RadioInfo.getNetworkService () & RadioInfo.NETWORK_SERVICE_DATA)! = 0) & {CoverageInfo.isCoverageSufficient (CoverageInfo.COVERAGE_MDS))}
Returns false; a Simulator or a real device with sufficient coverage
}
Returns false; real aircraft with insufficient coverage
}

public void run() {}
CoverageInfo.addListener (new CoverageStatusListener() {}
{} public void coverageStatusChanged (int newCoverage)
{Switch (newCoverage)}
box (CoverageInfo.COVERAGE_CARRIER):
System.out.println ("COVERAGE_CARRIER");
GPS.this.sendPoints ();
break;
box (CoverageInfo.COVERAGE_MDS):
System.out.println ("COVERAGE_MDS");
break;
box (CoverageInfo.COVERAGE_NONE):
System.out.println ("COVERAGE_NONE");
break;
}
}
});

While (! _stop) {}
GPS.this.getPoint (); try to get a GPS point
Make sure the radio is on and there is the coverage of the data
If (isCoverageSufficient()) {}
GPS.this.sendPoints (); Send the _Dans table to the web server
} else {/ / blackberry is out of coverage}
GPS.this.storePoints (); store the table _Dans on blackberry
}

try {}
Thread.Sleep(Timer*1000*60); pause the thread for a set number of minutes
} catch (InterruptedException ie) {}
System.Err.println ("Error:" + ie.toString ());
}
}
}
}

The 'getPoint()' method to get a coordinate GPS using LocationProvider.getLocation ().

The method 'sendPoints()' send the GPS coordinated to a web server using the HTTP connection:

...

HttpConnection con = (HttpConnection) Connector.open (URL); Open the connection URL
con.setRequestMethod (HttpConnection.POST); POST method
con.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
OutputStream out = con.openOutputStream (); display the results in a stream
out. Write (Data.GetBytes ());
int responseCode = con.getResponseCode (); Send data and receive the response code
If (responseCode == HttpConnection.HTTP_OK) {}
success
}
If (con! = null) con. Close; close the connection to the URL

...

The "storePoints()" method simply store the GPS on the Blackberry Persistent Store when the BB is out of coverage.

When the Blackberry is trying to send a GPS coordinate, but cannot because it is out of coverage, GPS data are stored on the Blackberry. My thread can sleep for 15 minutes before getting another coordinated GPS. If the BB is on the cover in the next interval of 15 minutes, the two coordinates are sent (the current and that (or those) that have been saved on the device).
It works very well.

However, now, I would put up a CoverageStatusListener so my GPS coordinates would be sent as soon as the BB is on the cover (and not wait for the next 15 minutes).
I tried to "COVERAGE_MDS", but he never seems to have triggered... but gets "COVERAGE_CARRIER".
I have a post on this here: http://supportforums.blackberry.com/rim/board/message?board.id=java_dev&thread.id=6076

My question is on the wire. Actually here is called the 'sendPoints()' method:
box (CoverageInfo.COVERAGE_CARRIER):
System.out.println ("COVERAGE_CARRIER");
GPS.this.sendPoints ();
break;

However, since my son sleeps, this method is not able to initiate a connection HTTP using MDS. I get an error in timeout after 2 minutes.

I'm not an expert on the threads. I think I have all the necessary parts of the code... but I'm not sure about how to reorganize this.
Can anyone help?

Thank you!

The network connection should be asked by a listener method. Do not perform any operation or the heavy within a method of transformation of blocking listener. Instead, you can create a new thread from the method which could then create the network connection to send your data.

Want to kill my thread of HTTP connection
