Just checking you are clicking okay on the emulator to allow it to continue; right?

cyberwit

I did but nothing happens the message just continues to show

Are you sure it can connect ok? Check the proxy settings for the emulator.

I have changed the code and i can now access my webservices through the J2ME however i have installed the app on my mobile phone how can i access the web services throught the app on my mobile phone if my web services are hosted locally on my laptop

You'll need to get your internet ip (not the 192.168.0.x), http://www.whatismyip.com/, and put that into your MIDlet to connect to. You might have to change some firewall settings to make the web services on your laptop available to the outside world.

You're probably better off using the emulator if you're still in development.
