Connecting up a mobile phone to a computer (via bluetooth?)

Question

Hi,
I'm looking for the best way to connect up a mobile phone to a nearby computer (wirelessly) so that they are able to communicate with each other.
Would bluetooth be the best way?
Would it be as simple as buying a bluetooth dongle for the computer, and writing a java application on the computer which accepts connections, and then writing a j2me application for the phone which connects to the computer? How would you find out what address the mobile phone needed to connect to?
Also, is there a better way of doing this without the need for a j2me application on the phone, such as a phones built in web browser? If I did this how would the computer be able to send information over to the phone telling it what to display? Would it be a case of creating an index.html on the computer and the phone would be able to display that?
Thanks for the help

At the PC end, your software will connect to the serial port corresponding to your bluetooth dongle. The two can communicate using a client-server relationship.
That is, of course, the bare-bones outline of quite a lot of stuff. Device pairing has to be done manually, since there is no method to do this in j2me. On many handsets, BT has to be launched before running a MIDlet that requires its services. All bluetooth dongles are not created equal, neither are all bluetooth managers. So you will have to deal with a number of specifics as you progress. I am not sure on this, but I think there are a few phone models that do have bluetooth but no serial port profile, so that's another point to check out.
AFAIK, the browser on a mobile phone cannot open local files nor access content via bluetooth -- html pages can only be viewed via the internet.
You will need to use the javax.bluetooth and, possibly, javax.obex packages.{color}

If you have further queries regarding the j2me part of your endeavour, you might get better response in the CLDC and MIDP forum{color}
