Networking idiosyncracies in S40 & S60 emulators

[tenren]

I have a midlet which makes HTTPConnections. Strangely it works in the S40 3rd ed. FP1 emulator but not in the S60 3rd ed emulator. I have API permission for http access in the JAD. Are there any differences in the implementation for S40 & S60 ? Thanks.

hi,

have you got any exception when running the same midlet on S60 emulator?
(you should trap IOException and SecurityException at least for Nokia devices and network operations),

regards,

Hi Peter,

I am not getting any exceptions. In the emulator, I opened the diagnostics pane, and the traffic tabs shows that a HTTP POST request was sent out. But on my server side, I did not get any connections. And the app just hangs.

By the way, I'm trying to find out how to debug the emulator & I posted my questions at http://snipurl.com/comlin . If you have any ideas, please let me know. Thanks for your help.

Here's an update. Instead of using the S60 3rd ed. emulator, I have reverted to using the S60 2nd ed. emulator. And I've noticed that I got an EOFException. The code that caused the EOFException is:

1 int httpCode = connection.getResponseCode();
2 if( httpCode == HttpConnection.HTTP_OK)
3 {
4 DataInputStream dais = connection.openDataInputStream();
5 int appStatusCode = dais.readInt();
6 ..snip..
7 }

The offending line is #5. Does anyone know why ?

Note that this code works fine in S40.

Thanks all.
