java.io.IOException: invalid port

I am developing a MIDlet to be run on
Nokia 6310i and I always get back
the IOException: invalid port when
making HTTP connection. Can anybody
explain why? HTTP should be supported
by MIDP 1.0.

Thanks,

Simon

Hello,

I took got same error but mine is pecuilar i am getting the response for first time but when making a second conneciton its giving this probelm.

Did u get the solution.

Can you show your URL?And does your network work well?

Hi,

The thing is that i got this error on my Series 40 Nokia 6610 mobile but it was running perfectly on the emulator.

my request URL is

first request is

[url]http://202.63.107.106/frontend?UID=Login[/url]$1000000$spw1_1_1@yahoo.co.in$sfqatest$ROCKET$5

this was working fine

but second request is going for toss and request is

[url]http://202.63.107.106/frontend?UID=GetMobileAlbums[/url]$1112315578084990:3f3a526d47a64:1000:spw1_1_1@yahoo.co.in:SFOSTG02$0

I get java.io.IOException:invalid port on the device.

I'm having the same problems on my 6280. I figured out what's it all about: having a colon ':' in your URL makes the phone think you're trying to set a specific port to connect to.

So try to replace the colons with something else and it will (most probably) work.

The same problem exists in gcalsync. I've suggested replacing : with %3a and that would hopefully help.

But Nokia ought to make sure this bug gets fixed. I upgraded to the latest firmware in my Nokia 5300 and the problem is still there.

Hi agam.jain! Welcome to Nokia Developer Discussion Baords!! :)

In which platform / SDK are you trying ? Have you tried in a real device ?

Gopal

Hello everyone, i am developing a j2me app, which run fine in emulator but gives java.io.ioexception -1 in nokia N97 mini mobile, please help me

Does it also say 'invalid port'? Just asking because in your other hijacked thread you do not mention that ([url]http://www.developer.nokia.com/Community/Discussion/showthread.php?231687-Java-io-IOException-in-J2me-application[/url]).
The "Post New Thread" button is just below the list of discussions on [url]http://www.developer.nokia.com/Community/Discussion/forumdisplay.php?16-Mobile-Java-General[/url]

ok thank you
