Client not getting response from server REST, JAVA?

Question

RESTful API

There is this form:

<form name="user" action="POST">
           Email: <input name="email" required type="email" />
           Password: <input name="password" required type="password" />
           Login:<input name="login" required type="text">
            <input type="submit" value="Submit" onclick="registration()" />
           </form>

The registration method that is called on click

var xhr = new XMLHttpRequest();
function registration()
{
 xhr.open("GET", "http://localhost:8080/user/login", true);
 xhr.send();
 success:  alert('Succes');
}

And here is the class itself, the method that handles the given HTTP "GET" request

@GET
    @Path("/register")
    @Consumes({MediaType.APPLICATION_JSON})
    @Produces({MediaType.APPLICATION_JSON})
    String user_info(@PathParam("email") String email, @PathParam ("password") String password ) throws FileNotFoundException{
        return "succes";   
    }

For several days I have been trying to understand what is wrong, the error is 100% stupid and is associated with an incomplete understanding of the topic, so I will be glad for your help.
The essence of the problem is that when the button is clicked, the registration () method is called, but js does not find the method processing it on the server at the specified path and issues 404 not found.
