How to insert multiple rows in same table at once

Question

hi ,
How can I insert more than one row in the same database table on single submit button.
(i am using the ADF , EJB and Toplink for this example.)
EMPLOYEEand DEPARTMENT tables will hold a common coloum deptno
The method I have tried is as follows.
I have created the UI that holds EMPLOYEE(DETAIL) details and a DEPARTMENT(MASTER) table and I have created two separate bean classes which hold the getters and setters for the corresponding tables.
I have created a method in Department bean which will be called when we add the employee details
public String addEmpdetails() {
this.employeedetailslist.add(empdetails);
return null;
where employeedetailslist is a Arraylist and I want to pass the reference of employeebean in the array list.
But this method will fail as I need to create the new employee bean object every time when ever I need to pass.
How can I store values of multiple rows in bean.
In the EJB session bean how can I commit multiple EMPLOYEE rows and DEPARTMENT values at once.

The use of &variable in a script is actually syntax for a "substitution variable" in the SQL*Plus tool (other tools may also do the same), not an inherent part of SQL or PL/SQL itself.
Whenever SQL*Plus is given a script it parses through it and if it encounters one of these it prompts for a value. This value is then substituted into the script before the script actually get's sent to the SQL or PL/SQL engine (process) on the database server. Once the script has gone to the database server it executes there and the results are passed back for SQL*Plus to display. However, the SQL and PL/SQL processes on the database server have no way to interface to the client machine, so they themselves cannot prompt for input from the client and you can't expect to prompt inside a loop as you are doing.
What you need is a user interface on the client that can prompt repeatedly for values and then re-send the script, or call a procedure on the database each time. This can be done using shell scripts or dos batch files (depending on your client being unix/dos based) or using a front end application tool such as Java, .NET, Powerbuilder, PHP, Application Express (APEX) etc.
