java udp request response mismatch

we are providing a java library to be used in web application.Library methods can be accessed from jsp pages by creating objects for corresponding classes.Upon a method call , library will send udp request to third party server for response.

If jsp page A calls library method B then request-0 will be transferred to server for key-0.If key-0 is obtained , then further method calls will be ignored.Consider B is called 4 times.4 requests namely request-0 , request-1 , request-2 , request-3 are transferred to server.Since we are using udp which is connectionless , key-3 is received before other responses.Key-3 is not for request-0.So it is ignored.Then Key-0 is received.This is not for request-1.So it is ignored.Similarly all responses are ignored. Now the library has no idea on how to handle these responses. Can anybody help in this?
 
It is sorta covered in the JavaRanch Style Guide.
