Can u tell me that what kind of program u want to make
using EJB, Are u creating Entity Bean if yes then what
database u are using...

in my appl. named Cargo Mgt Sys.
i have to make some validation and database
connectivity.
not know so much in detail abt EJB.
Which bean to be used plz tell me.

If ur Application uses database then you have to
create Entity Bean but first u have to decide that
which database u want to use becoz you have to apply
some changes in ur Application server  (JBoss)
according to database actually we have to tell the
datasource to Application server. I think mysql
database is suitable for ur Application, if u don't
have mysql then u can use Access also. First u tell me
about the database u want to use and tell me something
more about ur knowledge in Java means what is ur
comfort level in java programming, Have u worked with
jdbc,rmi etc this will be helpful to me to explain u
more about EJB.

it is obvious that you have no clue about EJBs.
EJBs are NO java beans.
