--->It connects to single session of Oracle and sticks to the single Oracle Database session.
--->when a button is pressessed in Form need to add the code for it and in oa pages
you will add a controller java code to handle events like Form Submit button clicks.
--->In handling the values for Form we use Block.Fieldname where as in oa pages
use getparamenter
