Checking the server connection from the device for uploading

[dhiraj.deka]

I have to upload a video file to the server from the device. But before that I am getting problem for establishing the connection to the server from the device for uploading.

Can you tell me how to establish the connection to the server for uploading a file?

Hello rageboy,
there are other threads related to persistence in JavaME in Forum Nokia Discussion Boards and articles in Forum Nokia Wiki. Take a look at them (such as Floggy Framework).

Hello rageboy,
Are u planning to get data that are stored in a remote machine (server)?. If it is your goal, it depends how the server is providing the required service (eg. login). If it is available through web service, you can use JSR 172 (Web Service Specification), by using WTK to build your stub (Stub Generator Tool). If it is available as http connection, you can use the HttpConnection class, like this example.

Thanx thiagobrunoms for your reply. I am trying to do that with HttpConnection only. I am getting problem in connecting the server means I am not getting any response from it, I don't know whether the connection is established or not? Can you tell me what is the proper way to establish the connection for uploading a file(video)to the server?

Hello,
When u send the request, does it throw any exception?!!? If so, past the exception result here. Otherwise, the server is not sending u a response. Try to get the response code through the HttpConnection object, such as httpConnectionObj.getResponseCode(), and check which code it is getting back, such as 200, 404, etc. U can see the meaning of each code here.
