Problems reading crypted string in DB2 8.2 via JDBC

[Andrea]

Hi,
I've a problem reading a field containing a crypted string. I read the
field via JDBC but when I decrypt the string I obtain a sequence of
strange characters (if I output them I obtain a sequence of ?
characters).
This problem occurs only with a database DB2 8.2 that has the
following encoding:

Database territory = US
Database code page = 850
Database code set = IBM-850

I tried the same code with another DB2 database with the following
encoding

Database territory = C
Database code page = 819
Database code set = ISO8859-1

and it works without problem.

I use the DB2 JDBC Universal driver and I read the string with
ResultSet.getString().
How can I properly convert the String?

I tried to convert the string with:
....
String cryptedString = resultSet.getString(...);
cryptedString = new String(cryptedString.getBytes("ISO-8859-1"));
....

and also with

....
String cryptedString = resultSet.getString(...);
cryptedString = new String(cryptedString.getBytes(), "ISO-8859-1");
....

but without success... :-(

What can I check? Any idea?

Thanks in advance,
Andrea
