Managing Entity Object and PL/SQL transactions

Question

Hi,
I have requirement to use entity objects and PL/SQL API in the same transaction.
First the data is created in the entity object and then API is called to do some validations on the data created through entity object.
I am not able to fetch the rows created by the entity object in the PL/SQL API until I issue a commit before calling the API.
Can anyone suggest me how to get the data in PL/SQL API which was created by the entity object without commit. As I want to have a commit only after API returns true.
Thanks in advance

Override the beforeCommit method of the main entity object of your page.
The commit will only take place if the PLSQL does not throw any errors.
See example below:
public void beforeCommit(oracle.jbo.server.TransactionEvent e) {
methodToCheckUsingPLSQL();
super.beforeCommit(e);
private void methodToCheckUsingPLSQL() {
try {
String sql =
"BEGIN check_my_entity(p_id => :1" +
", x_return_status => :2" +
", x_return_msg => :3); END;";
OracleCallableStatement stmt =
(OracleCallableStatement)getDBTransaction().createCallableStatement(sql,
DBTransaction.DEFAULT);
// Rebind parameters
stmt.setNUMBER(1, getId());
stmt.registerOutParameter(2, Types.VARCHAR); //x_return_status
stmt.registerOutParameter(3, Types.VARCHAR); //x_return_msg
stmt.executeUpdate();
String returnStatus = stmt.getString(2);
String returnMsg = stmt.getString(3);
if (!"SUCCESS".equals(returnStatus)) {
throw new OAException(returnMsg);
} catch (Exception e) {
throw new OAException("Error during methodToCheckUsingPLSQL. " +
e.getMessage());
