j2me post data limit

Question

is there any limit to send data from j2me device to server. I coded a application to send big data to server from j2me client. it works fine in wtk and sonyericsson emulator. but when i tried same code in real device, I can send only 6K data. then, app throws IOException. every 2K, I run flush function of outputstream to seperate data to chunk type.

anyway, is there anybody to send 20K data from j2me real device to server ? and which model ?

i tried it in SonyEricsson W710

Answer 1

What web server are you posting to? If IIS, this fix may help.

Answer 2

It is possible that the Mobile Network Operator blocks HTTP POST requests if their body is over 6Kb.

I would try to use a different network to check whether the limit changes (could be less, could be more).

Chunking may also be a bad idea, depending on the mobile network.
