Problem description:
Ok, so here's the problem. I have to connect to a legacy database that only allows NUMERIC's and FIXED_CHAR values. To try and get around the FIXED_CHAR problem I wrote a custom user type as listed above. The Uppercase user class is exactly the same but uppercases the values in the get and set. Anyway, it appears that a call to the SYSTEM_PARAMETER table returns the values no problem, however when I try and pull a row from the USER_PROFILE table it tells me "No data read" with the SQL error of 17024. When I first implemented the FIXED_CHAR user types, which I had found in the wiki, I couldn't get the app to run because it didn't know how to map SQL type 999. I managed to fix this by creating a new Dialect which only adds the following mapping:

registerColumnType( OracleTypes.FIXED_CHAR, 4000, "char($l)" );

Does anyone have any thoughts on why this would be failing?

Thanks in advance.
Adam
