One approach is to expose your Java functionality as a REST service.

Jersey REST end point

@Path("/rest/emp/")
public class EmployeeService {
    @GET
        @Path("/{param}")
        public EmployeDTO getMsg(@PathParam("param") String id) {



            return getEmployeeDetails(id);

        }

    }

EmployeDTO.java

String name;
String id;
String address;
//getters and setters

index.html

    
        
        
        
    

    
        

            
The ID is: 
            
The Employee Name: 
            
The Employee Address:
        
    

employee.js

$(document).ready(function() {
    $.ajax({
        url: "/rest/emp/10" (Your Rest end point URL)
    }).then(function(data) {
       $('#eid').append(data.id);
       $('#eName').append(data.name);
       $('#eAddress').append(data.address);

    });
});
