Trigger / Stored Procedure problem

[sjolin01]

I am trying to get a simple trigger that calls a stored procedure to work. Both the trigger and the stored procedure get created successfully using SPUFI. However, I am running into an error when I insert the row to fire the trigger. It seems that DB2 can't access or load the procedure being called. Here is the trigger definition I am using.

SET CURRENT SQLID = 'KZ7MPR';
--#SET TERMINATOR #
CREATE TRIGGER SC29_I AFTER INSERT ON GC01SCMY.SC29
FOR EACH ROW
MODE DB2SQL
BEGIN ATOMIC
CALL JUNK();
END#

The procedure it calls 'JUNK' is defined as

SET CURRENT SQLID = 'KZ7MPR';
--#SET TERMINATOR #
CREATE PROCEDURE JUNK()
LANGUAGE SQL
MODIFIES SQL DATA
NO WLM ENVIRONMENT
BEGIN
INSERT INTO SD29 (
SYS_PARM_NM,
SYS_PARM_DESC,
PARM_VALUE,
DB_TXN_SEQ_NBR,
DB_ACT_CD )
VALUES(
'AA',
'AA',
'AA',
1,
'A');
END#


When I try to fire the trigger by inserting a row into the SC29 table, I get the following...

---------+---------+---------+---------+---------+---------+---------+------
INSERT INTO GC01SCMY.SC29 VALUES('SK','SK','SK');

---------+---------+---------+---------+---------+---------+---------+------

When I lookup the SQLSTATE code of 42724 it says Unable to access an external program used for a user-defined function or a procedure. Any ideas what this could be?
