I do not think a Internet discussion board is any help in your state. I recommend to go out and find someone in your vicinity who has experience with web services. For example, go to a university with a computer science faculty and try to find a student who explains the details you need. If you dare to ask someone, this faculties do have public libraries. Start with a general book about web services. Then choose the technology you are comfortable with. Java-Server Pages (JSP) still require a webserver which you have to create as well.
For the start, I recommend to use the Nokia emulator on one PC and an Apache web-server on another PC. If you are not to Apache, go out for an old Mac OS X computer. Version
before Mac OS X 10.8 come with a Apache
bundled. Then you connect these both computers via one Ethernet cable. Then you install
Wireshark and watch the data traffic between the emulator and your server. That Apache
comes with PHP.
As you see, there are zillion of ways and I do not know which is the best in your situation. Therefore, ask someone in your vicinity and you can discuss all your requirements in much more detail.
