Hi,

What you want to do is to code a standard http client in order to avoid handling TCP connection "issues" (data plan or not/direct connection ...).

TCP connection have three use case.
First you have an adequat data plan which allows a direct tcp connection. Problem with that (in us) is that this data plan could be expensive.
conn=(StreamConnection)Connector.open("socket://testserver:600;deviceside=true");
Second solution (whithout the data plan) your server is on the same network than your bes/mds so that goes straight.
Third solution (whithout the data plan) your server is in another network so you need to ask your admins to open connections.
conn=(StreamConnection)Connector.open("socket://testserver:600;deviceside=false");
please notice the particularity of socket connection where you wants to add "deviceside" parameter.

Just code is as a "standard" java connection except some api are a little bit differents. I believe you can find easily such programs on google.
