EJB 3.0 insert data to more than 2 tables with one transaction

[nis siv]

We are using EJB3.0 + entities
in our project we need to save data to 3 to 5 tables.
They have relationship(one to many like ...).

can anyone please suggest a method to insert data to all the tables using one transaction .

(instead insert in master then merge detail then child of second ).


Thanks,

Nis

I don't follow the question - if your DAO code is called from an EJB method that uses CMT it will all be in one transaction. Am I missunderstanding what you are asking?

if there is some master child relationship between tables using the named query we can get all the data satisfying our criteria .like this is there any facility to insert the values using named query

you should put cascade attribute in your relationship annotation.

you can see this site he explain what you want exactly.
