getResponseCode() hangs on 9500

[kmaijala]

Hi,

I use HttpConnection to make HTTP requests from a midlet. Some times getResponseCode() hangs indefinitely. My estimate is that this happens maybe in one out of eight requests. A new thread is spun for each consecutive request.

On the server requests complete normally and the server log shows HTTP 200 even when the getResponseCode() is hanging.

The phone is a 9500 Communicator with firmware version 4.51(0).

Have you got workarounds for this?

Soku,

The sonyericsson link points to a thread where the poster has problems with HTTP-requests of certain content size. I'm sending HTTP-request with same content every time so there is no variation in content size and still the failure sometimes happens and some times not. The server supports chunked HTTP so that shouldn't be the problem.

The code works well in Sun WTK emulator. It also works on the real Communicator in one server environment. I will test it on Series 80 emulator on friday and get back with the results.

I browsed through this forum and indeed I found people having a similar problem. Some of the posts had 0 replies. Some told to close the stream and connection in a finally-block, which is what I already do. In one case a Nokia guy asked for a zip file containing the problematic code. Someone "improved stability" by recycling a thread to use it in multiple http requests.

Given the wide range of devices and platforms where this problem seems to pop up, I'm a little bit surprised that this issue has not been handled more thoroughly.

Hi,

I tested My code with Prototype_4_0_S80_640x200_MIDP_Emulator. Works fine; I can rerproduce the problem only on the real device.
