I am doing desing for a web based reporting application. I use JSP for view , servlets for controller and then DAO's for talking to database. Value Objects carry information back and forth. I user application server's Data Source for getting connections via thin driver.
Number of records in each table that I talk to are in lakhs.
If I introduce Session beans between servlets and DAO , how will I get benefited ?
Will it increase performance in any way ?
Please clarify.

I reckon your existing design is fine.
If it is read-only data and the volume is very high, in your case.. a few hundreds of thousands of records....then I do not see any reason why you should use EJBs....
The foll. J2EE pattern may be useful...
