HI all,

I am developing a j2me based application where i need to fetch data from server so i used j2me HttpConnection classes. But its working fine in the JDE / Emulator but exception is coming when i try make httpconnection in my BB9700  handset. 

I googled around for this problem and got to add "Deviceside=true/false;" in the URL. But still it didn't work.(Tried both true/false).

Please anyone help me out regarding this problem.

Thanks in advance

would be easy to answer if you can post the exception you are getting on your device. Also check these articles:

Thanks for your reply,

I have already checked these links. They didn't  help me out. 

Could you please give me any other links or codes.

Have you try wifi connection ?

add  ;interface=wifi

I am not using WiFi network. So i don't think it would help me.

Sorry, what you are trying to do is not straightforward:  Grab a great big cup of coffee and start here:

Then I would recommend this Thread, especially the 'Required Reading':

Finally try this:

I hope this helps.

I have tried all the things but still its not working. Please anyone correct me. Where i'm goin wrong. How its ruu=nning in the emulator ? Not in the device ?

[peter_strange]

Easy.  There are three connection method supported on the emulator:

BES (with MDS Simulator)

Direct TCP or carrier

WiFi

Whichever one of these methods you are using on the Simulator is not supported on the device, or at least not without some configuration.

So which of the three methods above are you actually using?  You will be specifying or defaulting one depending on the connection string you append to your URL.  The various articles I referenced talk about these connection strings so you should be familiar with them. 

[soumya_rout]

I'm using BES (with MDS Simulator) in simulator. And as per your(peter_strange) articles i have changed the URL as

httpConnection = (HttpConnection) Connector.open(url+parameter+";deviceside=true");

And its working good in simulator. 

Now my device only use the BES. So I implmentd the same but its showing Connection Fail 

My device uses Vodafone carrier but i'm not using their internet settings. I'm not getting where I went wrong.
