I'm using Castor V. 0.9.4.3 as Persistence Framework, a Sybase Database
(JConnect JDBC), and BEA WebLogic 8.1.
The problem is: I have several fields defined as NUMERIC(20,2) in DB
Tables. Those fields are defined in Castor Mapping file as:

Just started to look to use the java logging and got this error and
don't know why.  Used the example from
