Thread: Help with a Java Web aplication

Hi all. I want to know if maybe anyone cant help me. Im so bad in Java, just I programm in C or Phyton, but I need make a web aplication for can send commands to a GPS (Skypatrol TT8750), just need 3 datas: IP, Port, and a box for write the command, these command have to be convert to hexadecimal, and have add 00010400 at the start for exaple: the messege is hi, in hexa is:6869 then I have to send 000104006869 in the messege, I want to have the option for write the IP and Port.

I dont know if these is a hard work, but I really need help in that. I hope anyone can help me with these java code.

The GPS use GPRS, then Is possible send data by internet using UDP protocol.
The Gps is installed in a car, and sending hex data by UDP is not important where the user is connected, can be in a diferent country.
I forget write this, when i send a commmand, the GPS reponse too, with an OK, or with the petticion that I ask to him, for example a location, these messege is as TEXT, then i need read UDP incomming too, if I say I want to send by port 1722, the GPS send messege to by these port and at the same IP that is sendding the commands, and is importand to know these messege, then I need it too.

These work like a normal connection, like a phone. The GPS have a public IP, and i decide the port that is going to have when i programm the GPS before being installed in a car.

Just need send hex data by UDP, and read the incomming frames by the same port i decided to send the data.

Its same as Hercules work. In this link you can download hercules for see how work, Releases for Hercules | Drupal. I need same thing but in a java web aplication. and Just as UDP.

Thats ok

Thats the problem, i dont know anything about Java. I dont have done anything.
