Retrieving japanese characters through jdbc

Iam using Jdk1.3 and Oracle 8.1.7. My OS is in english.
The NLS of Oracle database is set to UTF8.
The oracle database contains japanese characters. Iam using a java
program to fetch these japanese characters. Iam using JDBC to do this.
When i fetch this data and display it on the console or write into a file,
it is written as '?'(Question marks.)
I even changed the setting of my OS to support japanese, even then this
continues.
can anyone help me on this.

You are more likely to find an end-to-end solution in the JDBC dforum, so I'm sending this thread there.
