Hi Tim,
thanks for your reply. Here is a possible scenario:

"An ISP has implemented a web site for e-commerce of web hosting services. The
site runs a quite complex java servlet application, based on an Oracle database,
accessed via jdbc. After order confirmations, the java application has to ask
one of the cobalt boxes in the Server Farm to actually create the domain the
custumer acquired."

I would expect that the CCE libraries allowed to do something like:

- cobaltConnect(cobalt-server, cobalt-password);
- if ok, domainCreate("example.com", "100MB", "admin-login",...);

A more difficult task could involve the possibility to start a domain transfer
for a customer which is changing his ISP. Considering that the previous ISP were
also using a Cobalt box, I would like to do something like:

- fromServer = cobaltConnect(cobalt-fromserver, cobalt-user, cobalt-password);
- toServer = cobaltConnect(cobalt-toserver, cobalt-user, cobalt-password);
- domainTransfer(cobalt-fromserver, cobalt-toserver, example.com);

How can be performed operations like that using CCE in Cobalt?
Is there any other platform allowing this kind of interfacement from external
applications?
