JTA and JDBC code

[scott miles]

I am bit confused when we connect to databse from java application.I have always worked on JDBC.

I have questiions about JTA and ORM like hibernate.

1) Does they also use JDBC internally or they have separate mechanism altogether?

2) I have seen some JTA api code but everywhere on different sites it does not say how do we get connection and execute the statement.

3)Can we couple JTA with JDBC like

//Step1 begin Transaction with JTA

//Step2 Now JDBC code for getting the connection ,statement and executing them.


//Step3 End Transaction with JTA

can we do the step 2 as i mentioned above or connection , statement needs to be acquired with JTA apis like XADatasource.?
