Event notification

Dear all,

How can I notify a database signal to client ( a forms 4.5 display)? I've created a small trigger from where DBMS_ALERT.signal() is called. I'm trying DBMS_ALERT.register() and DBMS_ALERT.waitany() in my form but it fails to compile (the error being: DBMS_ALERT must be declared).
Any suggestions?
TIA
