Japanese, Java and Postgres

I have a Java applet (1.1.5) running on win9x/IE/Netscape, 
using which the user can enter Japanese charactors. 

On the backend (RedHat 5.2 Japanese), I just installed postgresql 6.5 with 

./configure  --enable-locale  --with-mb=UNICODE  --with-odbc

And then I compiled the JDBC bridge. 

Now, when I insert some Japanese charactors in the DB and select it back, 
I get ??? marks. 

What I'm missing?? I'm not doing any encoding stuff programmatically... 

Please help me, and don't force me to go back to SQL Server !!
