JSON request for database
At the moment i'm working on a school project, we are configuring a Raspberry Pi as a Wifi AP with a captive portal.
We already build a .HTML landing screen, where the user can provide his name and ticketnumber. That information gets send to a java servlet with HTTP post.
In the java servlet the name and ticketnumber are saved as a variable.
The school provides a database where the name's and ticketnumbers are saved. We have to use a JSON request to check the name and ticketnumber, and that get a valid reply. I have no idea where to start, or how this will work. Maybe someone has a idea on where to start, or where to look or what to read. The JSON request we have to send will look something like this:
"function":"Check",
"teamID":xxxxx,
"teamKEY":xxxxx,
"firstName":"Henk",
"lastName":"Jansen",
"requestId":"15"
I think i have to call the database through the URL we got, and then use Java to POST the data the user provide's to the database.
I cannot use PHP or something, it has to be Java!
Sorry for bad English and thanks in Advance!
Ps. I'm not asking u to do my homework, i just need some directions :-)

Hi there, welcome to Stack Overflow. This question is a little broad, because there are many ways to do what you want, and many people will have different ideas. It might be helpful for you to search (on Google, e.g. "how to send JSON request in Java"), or ask (your teacher, or another developer working on the project, e.g. "can you explain what sending a JSON request means?"), and come back to Stack Overflow when you are stuck but have a more specific obstacle

You could look into googles java http client following the links below. This might be a good place to start.
