Question

I am trying to create some MySQL code that will invoke a Java program from a trigger.

Here is what I have so far:

CREATE TRIGGER trig_name after insert ON studentinfo 
FOR EACH ROW
BEGIN

END

The trigger content would then call the Java program. Is this possible?

A direct answer: no you can’t call a java method from a mysql trigger. If you had an oracle database you could, but not mysql.

To do what you want to do with mysql you can

• make the code that updates the database also notify the swing application. Or you can
• make the trigger accumulate data on pending operations in a separate table that you read periodically from the swing app.
