[Advanced-java] java persitence

[Mahesh Geeniga]

Hi,

What is the best (performance wise) way for making java objects persistent ?

After searching the net, i found lots of ways for saving the state of 
objects.
But my application needs a fast method for saving and retrieving data 
and i am not sure about which approach to use.

- I do not want to use java serialization, because i want something 
faster and more efficient.

- JDO looks promising, but i have read that it is slower than straight 
JDBC by about 20-30%.
    Has anybody used it extensively and what was your experience?

- straight forward and direct mapping of java objects to database tables 
using JDBC seems like the fastest way to do it.
    But i want to explore other options before i commit myself to 
writing and maintaining all the SQL code.

Any suggestions or pointers to other ways of persistence are welcome.

thanks,
Mahesh
