I am querying a very large Data Set 5 Million rows and the report
generation is slow. Is there any way I can generate the report every
night and deploy it as a HTML so that end users always see the HTML and do
not have to run the report query and load the server.

Not sure if this is possible. Anyone.

A slightly different way, that should work...

(Assumes a linux server, with some kind of a static web server install, be
it apache or something else)

wget -O /path/to/apache/root/dailyReport.html
" http://birt.server/run?__report=myreport.rptdesign&myfir stparameter=paramvalue&mysecondparameter=anotherparamval ue"

There may be a way to do it within BIRT directly, but if so I don't know
what it is...

You can use the Engine API RunAndRender task to generate your report as
an html file and drop it into a directory of your choice.

See the BIRT Report Engine API page.
http://www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.p hp

You could then use cron or similar to start the report generation each
evening.

[Another message in this thread describes something similar.]

OpenSymphony's Quartz comes to mind. Set up a "job" in Quartz to
do the report generation at a convenient hour (in the middle
of the night). Set the output of the report to the expected
location in your Web app's directories. BIRT's runtime engine

http://www.eclipse.org/birt/phoenix/deploy/

would crank out the report. Your code would update a "reports"
table in your database with a new report entry.

You choose your design: save the report to a blob in the "reports"
table or save it to the file system. (I usually prefer the latter.
That requires that I save the filename as part of each record in
the "reports" table.)

The Web page which provides links to daily reports would
of course be dynamic -- i.e., your code should read the db table
which maintains the link/filename information for each daily report
and create the appropriate links.

Quartz is here:

Quartz tutorial:

Here's an O'Reilly article to get you started:

http://www.onjava.com/pub/a/onjava/2006/03/01/job-scheduling -in-web-application.html

And finally, do it in Spring:
