JProgressBar and DB

Hi guys,

Quick question: I have a query to the db that takes a while (~15 sec) I would like to let the end-user know that something is going in the background so don't exit.

Anyway, I don't know how long the query will take and I don't know how many records it will obtain, how a JProgressBar can help? and/or if anyone has better alternative.

From the API documentation for the class:

"To indicate that a task of unknown length is executing, you can put a progress bar into indeterminate mode."

I will leave you to read on from there.
I agree. Here's the link:
