Limit num of connection on webservice

Question

I want to control the number of connection on the webservice for each client
account.
I am thinking to provide a client class encapturing all the client calls to
the webservice. Using the client class to control the number of connection.
public class WsClient{
private int conNum=1;
public WsClient(String userid){
conNum=getConNumFromServer(String userid); //get Num of Conn from server;
public void synchronized wsCall(){
while{
if (conNum<1)
wait(this);
else
break;
conNum=conNum-1;
callWebservice();
conNum=conNum+1;
Welcome suggestions on how to accomplish the goal.

Hi Stephen,
You might want to take a look at the JAAS example, and docs:
http://e-docs.bea.com/wls/docs81/security/fat_client.html
(SAMPLES_HOME\server\examples\src\examples\security\jaas)
Limiting at the web service connection level may prove difficult.
Sorry, not much help,

Hi Bruce,
Thanks Bruce. The webservice is provided in B2B circumstance, so I want to
control each user (license) 's connection. Such as UserA = 4 connections,
UserB = 2, etc.; User need pay for each connection he wants. Exceeded
connection will wait or timeout.
Since it is purchasing transaction, I can not use async. More advice on
how to control the client connections of webservice are welcome.

Hi Stephen,
So, to rephrase, for a specific user (known to the server) you want to
throttle the number of concurrent webservice connections to a
webservice? So for UserA = 4 connections, UserB = 2, etc.; connections
and others that attempt to come in past the given max would simple wait?
Seems like having an async web service that writes into a JMS backend,
you could easily queue requests, then drain them as needed. Or maybe a
cookie scheme managed by the server.
Maybe if you could elaborate on what problem you are trying to solve?
Thanks,
Bruce
