    Hi Andrus,

    Thank you for the respone

    There is little catch in our existing design. Here is the design

    My application interacts with it Manger applications (could be more than
    one) that are running either on SQL server or Oracle. Schema is same for
    both the vendors. Manager application actually holds information about it's
    database connection.

    User who is using my application will be one Manager at a time. So, when
    user login to my application, system connects to the manager he is
    intereted, bring all connection details and keep them in HTTPSession. For
    Cayenne, I would like to keep DataContext in HTTPSession so that it will be
    user specific.

    I could not understand your previous response. After setting DataSource on a
    node and keeping DataContext in HttpSession affects all other users as well?

    What happens on below scenario?
    Using my application User A can connecto Manager A that is running on SQL
    Server Database.
    Using my application User B can connect to Manager B that is running on
    Oracle.

    If possible can I have sample code or examples for Spring+Cayenne
    integration. Unfortunately I am new to Spring as well :(

    I hope you understand my text :)

    Thank You
    Sudheer
