If a user logins at my application (with username and password) the
username and password would be sended to my
web service and checked if this is right?

Yes.

And how can i make this? It's my first time for developing a java web
service!

Web services are code just like any other code.
You will need a Java web container like Tomcat and you will
make life a lot easier for yourself by using a toolkit like
restlet instead of handcoding a servlet.

I have already created a web service with reslet and this is a great
framework!
I am now trying to let it work with a database (jdbc)

What do you prefer to use for the database?
Object Database (db4o) or xml Database or jdbc (mysql)?

I would go for a regular relational database.
Like MySQL.
But there are also other.

How can i make a login webservice with mysql?

A login web service is like any other web service call.

But login is not RESTful.

You should check in each call.

The web service check in MySQL just like any other Java code.

So I can make a seperate web service for my login and logout and have
a restful webservice for the other stuff?

No.

Every RESTFUL web service call should check credentials without
there being any session login.

I can save the username from the login and use this in my restful web
service?

No.

You send username/password with every call. No special login only call.
