Java RPC server on os/400 cannot process extended alphabet

Product/components used and version/fix level:

os/400 V7R4MO, EntireX Java RPC Server, Version: 7.1.1.50
z/OS 2.4, EntireX 10.9.03
Windows Server 2026 Standard, EntireX 10.9.15

Running Java RPC server on os/400 but it does not process special characters such as ÁÉÊËÍÎÏÓÔÖÚÛÝáéèëêíïîôöúûý

Tested with the broker on Windows and z/OS.
Tried using encoding ISO8859_1 for JVM and RPC server but without difference.
Tried using CONVERSION broker attribute without success.

Providing more information on the RPC server execution such as CL and Java, RPC trace, brokers attributes in the attached file.

Will appreciate your advise how to configure the conversion.

Regards.
Leonard
