We do no recommend to register deployers programmatically. The recommended
approach is to declare them in the component.xml. This allows Carbon kernel
to read and register deployers before initializing Apache Axis2 engine. If
you register deployers programmatically, Carbon kernel does not have any
control. Your artifacts may get deployed after server has been started.
I.e. after the transports are started.
The above approach perfectly fits if the deployers do not get added or
removed dynamically. But in your case, we cannot predict the number of
deployers. I.e. for every new virtual host, there will be a new webapp
deployer. Therefore we cannot list all the deployers in the component.xml.
Now we need to come up with a solution to support this requirement.
Thanks,
Sameera.
