Re: Handling multiple EIS instances with one resource adaptor

Connector 1.5 expands your choices of how to do this.  In 1.0 you have the
following options:
1) one resource adapter per EIS
2) one resource adapter with different connection parameters for EIS
(depending upon whether you want the client app to choose instances or the
resource adapter to do it).

In 1.5 you have the additional choice:
3) one resource adapter with a connection factory for each EIS that you
want to access
