Calling Java App through Oracle 9i Database

Question

Hi there,
I have a Java application that is being invoked through an AFTER INSERT trigger on a table. The trigger calls an Oracle plsql wrapper stored procedure which fires the Java application and passes a parameter value.
Problem: Java application should be invoked only once the commit after the INSERT statement is issued. I am unable to do this by this by using an INSERT trigger as the commit; takes place after the Java app is called?
I know and understand that ON COMMIT TRIGGER IS NOT POSSIBLE IN ORACLE.
Is there any other possible way to solve this problem?
Cheers.
Rohan

Answer 1

Unless the behaviour of DBMS_SCHEDULER has changed recently, it does a commit as part of the create_job call (or whatever subprogram you use) so is not suitable as a replacement for DBMS_JOB when submitting a job as part of a transaction.
So, what you say is a good approach but using DBMS_JOB.
