I am pretty new to firebird (still at the review stage) and would
like to know if I can use a trigger to call UDF library to send a
message via sockets to java packages running on client machines?

If not, can I send events to different packages (either in C++ or
java) residing on different
machine to the database? I have read something about
POST_EVENT and understand the concept behind it but do not understand
how in reality I can get them working? Is there an example I can
download?

Does the Firebird ODBC or JODBC driver support the event facility?

Any help or advice would be much appreciated.

Thanks in advance!!!
