Babi,
If you need the specific connection then your best best is to write a
driver bridge plugin. You can get the connection object and make your
call before the default driver calls your dataset. Take a look at this
blog entry:
http://birtworld.blogspot.com/2007/01/birt-connection-poolin g-continued.html
Your requirement is not connection pooling but the article(s) cover the
driver bridge extension.

Athul,
I am not exactly sure what you are trying to do, but if you want a
stored proc to run before your standard dataset, create one datasource,
then one dataset that calls the proc and one dataset that reads from the
table. Bind a hidden table at the top of the report to stored proc data
set first. Below it bind your second dataset to the second dataset.
