Data representation problem

Hi everyone,  I have a problem that I am hoping someone on the group can help
with.

We have a JAVA application on an NT Server using IIS(Java 2 for NT). It connects
to the AS/400 using a Java socket.

The application works fine on a CISC V3R2 machine.  This machine was upgraded to
a RISC machine running V4R4 with the latest Cum Pack.

When we use the application on the RISC machine  any Single data display field
returns the correct data, but any multiple display fields
(ie returning a list of details from some sort of query) returns as all clear
Squares(on IE) or Question Marks(on Netscape).

The RISC machine is setup identical to the CISC machine (The Software vendor
that supplied the application has this working OK on a V4R4 machine)
I am puzzled as to what is causing the issue.

The Database Group PTF is not applied(but will be over the weekend)

Does anyone have any pointers to help me get to the bottom of this strange
issue.

TIA
Dave
