I have a desktop application(Swing) that run BIRT reports and i want to place a progressbar with a status label that show to the user the report generation status and progression in percentage, Is it possible to retrieve report progression in percentage ? How ?

I use an IRunAndRenderTask to execute the report .

Alessio,

Currently the engine does not provide this feature. If would be
difficult to know how much data is going to be retrieved. You could
write some code to simulate percentage based on number of data sets and
use the progress monitoring interfaces to see when each is processed but
it would not be very accurate.

Not yet as the calculation could be wildly inaccurate.

One more question :

Each time that a task is started the start or ended an event is generated, to calculate the percentage i need the total number of task that a report will run, is it possible retrieve that value ?

Thanks again.

Do you mean like start page and end page or start and end query? I do
not think there will be an easy way to determine this.

You can the number of queries by looking at the report design, but as
for the others, I do not know of a way to know before the report runs.
The report has no knowledge of how much data is going to be processed
from the data sources.
