ULC executes the presentation logic on the server side.
The server doesnot block, it only responds to the requests from the client.
So showing the splash screen and starting you operation in the same server
roundtrip will not help.

Using the progress pane is the right approach.
Which version of ULC are you using?
The ULCProgressPane contribution on the community has been ported to ULC
6.1.
Moreover you can use ULCPollingTimer. Lets say you start you action by
pressing a button:
In the ActionListener for the button: Start PollingTimer and Show the splash
window
In the ActionListener of PollingTimer: Do your task and at the end Close the
splash window.
I hope this helps.
Thanks and regards,
Janak
