Sockets!!!!

[grahamhughes]

I was having success using the Connector class with URLs like "socket://ip-addrort" on all of the Sun device emulators, and the Nokia Series 40 emulator. Of course, on the 7210 emulator, it tells me that I can't access a system class. I've tried tricking it, by subclassing the systems classes in my own class, or creating my own classes in a system package (because they obviously can access system classes), but then the phone says "can't create class in system package". So far I'm out-smarted.

I had assumed that sockets just weren't possible on such devices, and have started to build an HTTP based solution instead. But today I see a product (http://www.reqwireless.com/emailviewer.html) that apparently talks POP3, IMAP and SMTP on Java phones, including the 7210 (indeed, the whole Nokia range). I guess they might actually be diverting requests via their own webserver, but I kind of suspect that they might know something I don't.

If they do, they have a competitive advantage. Which doesn't seem very fair. Won't Nokia tell us all how to do this!!!???!!

Hi all
I tried using Socket :// and also Datagram ://
But i get

javax.microedition.io.Connector
java.lang.classNotFoundException
com.symbian.midp.io.protocol.Datagram.protocol


But i found that nokia support TCP /UDP support according to their documentation.

Why is that http support given and its work fine ,but not TCP / UDP.

Can any one give me some solution for Datagram and Socket over the 60 series phone.

As far as I know they stopped supporting socket connections since Symbian OS 3.16 or later for security purposes (e.g. I got a status = -18 Exception Msg, which means, that the Symbian TCP-Stack isn't ready, and after setting the boolean 'timeout' to false, I got a -33 (cancelled). These are error messages coming from Symbian). So to establish a socket connection one first has to flash his phone.
:-((
Honestly, I can't understand, why Nokia did not inform us about this. I really would like to know, whether Nokia is planning with sockets in the future or not and if so, which devices will be concerned.

Hi ,Firstly thanx for ur reply.
Im still not getting Socket:.// (TCP) and Datagram://(UDP).

I tried using HttpConnection class for http://www.yahoo.com.
But the problem is , im able to get the requested page from emulator.
But NOT from the 3650 phone.

But i got this exception

java.io.IOException status=-33

and sometimes

java.io.IOException status=-20019

Could you please tell me what would be this and what does this status value means.

and is it possible to connect to any http(URL) from 3650 phone using HttpConnection.
