Creating Datasource Dynamically - Help Needed.. Urgent..

ayyalaraj

Hi,
I am trying to develop reports that are generated completely dynamic. As I am new to BIRT, I am wondering whether I can do this or not. My scenario is like this:
User will come to view reports based on his id, ex. client id. I will get this id from session. I need to generate reports based on this id. I also need to connect to respective database based on this id. I mean, my database is not static for creating Datasource and use it. I need to generate the datasource information on the fly and generate the reports.
I am thinking it is possible using JNDI URL and other stuff. But I don't know whether it is possible in BIRT or not.
Is it possible to create datasource or dataset dynamically? If yes, how can I acheive that in BIRT.... Please help....

Thanks in advance...
