How to handle multiple connection through JCO

Hello JCo Experts,

My requirement is as follows:

> I need to create a Web Dynpro Java Application

> I have multiple users (different Users on SAP System).

> I need to execute BAPI/Module Functions through these multiple users.

Example:

Users: A and B

User A has logged in from a remote location

User B has logged in from a another remote location

both users have logged in through SAP system Login Ids

Two JCo Connections should be created and all the request from User A must use Connection A and request from B must use Connection B.

> The connection should be created at first time when user login first time.

How can I handle this scenario through JCo or other way. I have multiple BAPI/ModuelFunction which I need to execute but with User specific.

waiting for positive response.
