The @javax.ws.rs.CookieParam annotation injects the matching cookie parameters present in the HTTP headers into a class field, a resource class bean property (the getter method for accessing the attribute), or a method parameter.

The following code snippet uses the Default-Dept cookie parameter present in the request to return the default department details:

@GET 
@Path("cook") 
@Produces(MediaType.APPLICATION_JSON) 
public Department getDefaultDepartment(@CookieParam("Default-Dept") 
   short departmentId) { 
  Department dept=findDepartmentById(departmentId); 
  return dept; 
}
