I have done a project where the mobile sends it's latitude and longitude to the server every 15mins. To connect with the server every time i used to enter the IP address of the server dynamically in my application. Whenever i tick an option in my app mobile sends an notification to the server with the details of the option that i checked(Check Box) and everything is working fine. I used the code like below:
String url="http://"+ipaddr+"/SFTS/updateLocation.jsp?empid="+empid+"&lat="+lat+"&lon="+lon+";interface=wifi";
Now i got a new Internet connection with static IP. And now i unable to send the notification to the server. When i am checking a checkbox it is displaying nothing either in the server or client. I tried using deviceside=true; deviceside=false but all my attempts are in vain. What is the problem here? Please kindly help me
The problem is with the apn. We should include ;deviceside=true;apn=airtelgprs.com in the url is the first option or go to Options -> advanced Options -> TCP/IP -> check the option APN Settings Enabled and give APN: airtelgprs.com. It works fine

I didn't know it was possible on iOS but lately I went to Japan and one of the free wifi apps wanted to install profile into my iPhone. When I confirmed installation it simply opened Safari with 127.0.0.1. It loaded some page and downloaded profile from there. How do I host some page on iOS?
Creating web server is nothing hard. It is lot of coding of course, but the principle is pretty easy.
There is lot of 3rd party libraries on the github (GCDWebService) just try to search for "ios http server"
To create it manually you need few steps:
1) With the help of CFSocketCreate you open new socket with specific port (standard HTTP 80, or secured one 443 should be forbidden without root access rights) what going to listen on network interface on incomming requests.
2) You need to prepare some receiver what will be triggered as soon as some request income. You can use NSFileHandle class and register NSFileHandleConnectionAcceptedNotification in your notification center. And allow background mode with acceptConnectionInBackgroundAndNotify method. But I recommend to read the manual first
NSFileHandle Apple documentation
3) Process the incoming request. The selector what you register is called and in NSNotification.userInfo property is the incoming request, and you can generate some page here and open it in safari, or in your app or do whatever you want.
4) If you want received some POST data or streams, there is needs to register NSFileHandleDataAvailableNotification what trigger selector as soon as some data to read are available.
I am trying to implement a splash page/ wifi landing page on my existing public wifi network, using the DNS method mentioned in Wiki, in which I host a custom DNS server, that will redirect ALL dns lookup to a local address where a web server is hosted, for all user before they click agree.
After the user clicked agree, my custom DNS server starts returning correct ip for the look up, thus, user will be able to get online.
note: We totally understand that this is in no way secure our network, and even putting our network at risk. But the goal here is to just to pop the landing page up in front of our users.
This approach actually works on Windows Phone (Windows 8 I tested) as splash page, and even on a computer when I try to open a random website, it redirects me to my page, and after I hit agree, I can get to the internet.
When I try it on iPhone/ Android, once I connect to the hotspot, the splash page/ wifi landing page appear as expected (because the device is trying to verify internet access by going to the set of pages) However, after I click agree, and allow internet access, both iPhone and Android splash screen will not go away. I have to force iphone to "use this wifi without network" to exit.
I wonder if there is a special (javascript?) method I can call in the page, or some package I need to send to the device? I noticed on iOS, if I click a link to the App Store, the splash page go away without disconnecting from the network, So, I guess I am missing something here.
For example, clicking the link to the iOS StackOverflow App on iOS device can be a workaround.
Had been googling around for a week now, nothing seems to came up.
by the way, I am building my custom dns server on node js, with the module dnsd.

=-=-=-=-= edit =-=-=-=-=-=
I also uploaded a demo of my code on GitHub:
https://github.com/kylelam/dnsd_wifi
To test it, run it in your local network (sudo node demo.js). Then, change your phone's dns to your machine's IP. Disconnect your phone from wifi and connect to it again. (on iOS, you might need to go into detail, and enable auto-login, and auto-join, or if you can't, just reboot.)
*note1: the server will need to run on port 53, and 80, so it need sudo.
*note2: please don't laugh at my code, I'm very new to this. But please do point out.
*note3: you will need to npm install these packages: os, express, dns, dnsd
ttl set to 0 might be the cause of the issue, try a different value like 5.
OK, this is weird.
We have a test website (just a payment form) here: http://blog.inglesen100dias.com/
The problem is that everyone I've talked to but me can see the form (our hosting provider, other coworkers in different states/countries, etc). Me, I see a 403 forbidden error, "You don't have permission to access / on this server."
We made a change earlier today in that subdomain, changing the A record to point it to a different server. But for some reason everyone but me can see the new page where it's pointing at.
I've deleted the cache, flushed the DNS (I'm on Windows 8), entered the website with my cellphone (same error)... so I don't know what else to do. My impresion is that when I access that URL, it's still trying to open a location in the old server (where the domain originally pointed), instead of in the new server. Why this only happens to me?
Any advice would be very welcome!
UPDATE
I've turned-off the Wifi in my cellphone (it's connected to the same network as my computer) and now it shows the right page! If I turn the wifi back on, then it shows the 403 error again...
Can it be a problem in the router?
I restarted the router and now it's showing the right page!
I am trying to use push notifications for OS < 7.X .
I downloaded the sample server / client code. I deployed the client code on my device and the low-level-sample code on the tomcat provided.
For the record , when i registered for push notifications here i registered using the BIS option. Now that i was actually given a blackberry i was informed it is using BES ( i dont think though this is the root of the problem that i am going to describe..).
On the device , in the sample application i put all the correct settings given from the email i received.
Both my pc which is running the tomcat server and my phone are connected to the same wifi.
I am trying from the device browser to connect to the server , eg https://196.84.32.112:8443/low-level-sample
and the browser opens the page normally , meaning that i am able to connect to my server from the mobile.
Now when i hit register from the device sample app ( i have tried both BIS/BES options on the settings ) , i always get the following error :
Request to register failed. Cause by java.io.IOException: Network operation[Subscribe] failed. Make sure that Content Provider URL is accessible.
In the log i get :
Opening URL: my server url appended with info like username/password/model/connection type etc
Content Provider network command [ Subscribe] failed , caused by could not connect to 196.84.32.112:8443
Command "register" failed with error: java.io.IOException: Network operation[Subscribe] failed. Make sure that Content Provider URL is accessible.
A thought is that i should register again for new push keys and use the BIS/BES option instead of only BIS , but here the problem seems to be no connectivity with the local server , not the RIM server. I already tried to register though and i am waiting for the mail with the new settings.
Also i am a bit confused with the BIS / BES option. I have no idea if my users will have BIS or BES enabled so what do i put in my code ?! In the sample application it asks me to select between BIS or BES but when the app is going to production and i need to programmatically make that choice what will i choose?! Or this choice is made only for the evaluation/development of the app and on production there is another server ?
I think all the right things have been said here, but I'm hoping we can consolidate some of the answers, and wrap this question up.
You haven't shared your code, which makes things more difficult, but many people use the RIM/BlackBerry provided PushDemo source, where a connection suffix is hardcoded in /pushdemo/com/rim/samples/device/push/PushUtils.java:
private static String getConnectionSuffix() {
return ";deviceside=false;ConnectionType=mds-public";
}
I'm also guessing this from having read your other question.
By doing this, you've hardcoded the BlackBerry transport type of BIBS. BlackBerry supports many different transports, like BES, BIS, BIBS, or WAP. The BIBS transport will send the request from your device, out to BlackBerry's servers, which are on the internet. (Note: this part is probably confusing to an iOS/Android developer, since those platforms don't provide Apple/Google network intermediaries to relay normal HTTP/S traffic)
Then, the request is relayed to your server, which is at:
196.84.32.112:8443
I'm pretty sure that TCP/IP endpoint is not available from the Internet (I can't reach it). So, that's why it fails for you.
You can take this URL
https://196.84.32.112:8443/low-level-sample
and paste it into your BlackBerry device's browser, and it will work. Your device is configured for BES, which uses your company's internal servers. Those internal servers can reach the 196.84.32.112:8443 endpoint, so it seems to work for you. But, that's because you haven't hardcoded the transport, as you have in the push code that uses getConnectionSuffix(). The device browser is smart enough to figure out a transport that works, and BES works to reach that intranet server.
Hopefully, that explains the confusing part.
Solutions
As others have said, a solution is to get your company's IT people to make IP address 196.84.32.112 and port 8443 accessible through their firewall. That would allow the BlackBerry servers to reach it successfully.
Another solution would be to change the PushUtils.java code to avoid the BIBS transport:
private static String getConnectionSuffix() {
return ";deviceside=false";
}
If you want really flexible code, then I'd suggest rewriting that PushUtils.java code, because it appears to use the pre-5.0 HTTP connection logic. ConnectionFactory in OS 5.0+ makes this easier, and more robust, when supporting multiple transports ...
To answer your question about supporting users with multiple transports, take a look at this blackberry.com example, specifically the MyConnectionFactory class. It allows you to select which transports your app allows, and which it tries first.
Ultimately, the decision to make your server public or not depends on how it's going to be used, and whether you'll have non-corporate internet clients trying to register with your corporate server.
Let me first explain the registration flow for BB Push Demo:
When you click on Register the device will
Inform your web application that the device wants to register. For this it will send the information about the device to your Web Application (the so called ContentProvider). You are expected to store that information in your database. This step happens in the ContentProviderProtocol.performCommand() method of the push demo.
Inform the BB Push Server that the device wants to register for receiving push notifications from your application. This happens in the BpasProtocol.register() method of the push sdk.
Step 1 is only necessary if you want to know who all are registered for push notifications (maybe if you want to send individual push notifications to each device and not broadcast the message to all registered users). In that case, you will probably need other information like that user's preferences etc for customizing the push anyway.
Now the error you are getting is from the step 1. For step 1 to succeed, your device should be able to connect to your web app which it is not able to.
To solve this problem, either you have to make your web app publicly accessible (and be ready to handle the load) or comment out the step 1 from the app by making ContentProviderProtocol.performCommand() return without doing anything.
PS: The webapp used in step 1 need not be same as your push initiator. The webapp is simply being used for tracking who all is registered for receiving the push and should ideally be located in the cloud on a distributed architecture if you expect a lot of users.
Is there any specific settings for third party app using internet connection because when i try lo login,app need network connection and it ask for APN.
I gave APN as "blackberry.net" as given by vodafone but it gives me "tunnel failure error" or "DNS error"
What settings are required so that third party apps can use internet
This is not a programming question.
If you are trying to use a third party app, and you are not able to (tunnel failure) set the apn in your phone in the following way.
Some third-party applications might require a direct TCP or HTTP connection to the Internet. For example, a stock price application might require a connection to the Internet to retrieve the latest stock prices. The TCP settings might be required for the third-party application to access the Internet.
Note: Contact your wireless service provider to obtain the Access Point Name (APN), user name, and password.
On the Home screen of the BlackBerry smartphone, click Options.
Note: Depending on the theme running on your BlackBerry smartphone, you may need to click Settings, then Options.
Complete one of the following:
For BlackBerry® Device Software version 4.1 or later, click Advanced Options > TCP/IP
For BlackBerry Device Software version 4.0 or earlier, click TCP/IP.
Enter the APN, user name, and password obtained from your wireless service provider.
Press the Menu key and select Save.
This information is from here
Try using "WWW" as access point for Vodafone. if still not proper check out for connection types. or just add ";deviceside=true" at the end of your url.
