Why is this table trigger not firing when insert/update from servlet?

Question

Hi!
I have this servlet that parses XML and stores values into Oracle tables. I have created a table trigger so that when one table is updated, a trigger is fired and the current system date is store in another table's field.
I have tested the trigger in Toad and it works, that is, if I update the table that the trigger is set to, the SYSDATE is stored as intended.
Here is the trigger's code:
DECLARE
tmpVar NUMBER;
NAME: transaction_time
PURPOSE:
REVISIONS:
Ver Date Author Description
1.0 9/14/2007 1. Created this trigger.
NOTES:
Automatically available Auto Replace Keywords:
Object Name: transaction_time
Sysdate: 9/14/2007
Date and Time: 9/14/2007, 8:00:42 AM, and 9/14/2007 8:00:42 AM
Username: (set in TOAD Options, Proc Templates)
Table Name: MS_RESLIMITS (set in the "New PL/SQL Object" dialog)
Trigger Options: (set in the "New PL/SQL Object" dialog)
BEGIN
tmpVar := 0;
UPDATE MS_Misc SET mi_lastrun = SYSDATE;
EXCEPTION
WHEN OTHERS THEN
-- Consider logging the error and then re-raise
RAISE;
END transaction_time;
Now, when the table is updated by the servlet, the trigger does not fire. And here is the code from the servlet:
--- <start of code> ---
boolean recordExists =
this.isRecordPresent("MS_ResLimits", "rl_compcode",
compCode, url);
Connection rlConn = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
rlConn = DriverManager.getConnection(url, dbUser,
dbPwd);
Statement stmt = rlConn.createStatement();
PreparedStatement xmlUpdate = null;
if (recordExists) {
xmlUpdate =
rlConn.prepareStatement("UPDATE MS_ResLimits SET rl_compcode = ?, rl_maxreslimit= ? WHERE rl_compcode =?");
xmlUpdate.setString(1, compCode);
xmlUpdate.setString(2, maximumReservationDate);
xmlUpdate.setString(3, compCode);
} else {
xmlUpdate =
rlConn.prepareStatement("INSERT INTO MS_ResLimits VALUES(?,?)");
xmlUpdate.setString(1, compCode);
xmlUpdate.setString(2, maximumReservationDate);
} //end-if-else
int n = xmlUpdate.executeUpdate();
rlConn.commit();
} catch (Exception ex) {
out.println(ex.toString() +
"-> error inserting Max Reservation Date<br>");
} finally {
if (rlConn != null) {
rlConn.close();
} //end-try-catch-finally
--- <end of code> ---
What causes the trigger to fire? the commit? My understanding is that executeUpdates are in autocommit mode by default, or am I mistaken? Do I have to programmatically send something to the DB so that the trigger fires?
BTW, I'm using JDeveloper 10.1.3.3.0. The project is being compiled with Java 1.5.0_06. The servlet is running in OCJ4 standalone. DB is 10g (don't know the release version).
...and, for some reason this message is not keeping format from my edit window to the post...
Thx!

You are supposed to be able to preserve you formatting using the <pre></pre> tags but I can't get this to work either<br>
