AS2 Sender problem with German "Umlaute"

Hello experts,

I have an AS2 sender adapter sending orders into my SAP system. My problem is though that it deletes all German "Umlaute" before converting it into XML.

I used to use the "CallBicXIRaBean" to do the Encoding with ISO-8859-1 and it did not work. So now I am using the "CharsetConversion" to do that but it still does not work.

In the Module of the AS2 sender I am using:

1) CharsetConversion

- sourceDest --> MainDocument

- targetDest --> MainDocument

- sourceEnc --> ISO-8859-1

- targetEnc --> ISO-8859-1

2) CallBicXIRaBean

- mappingName --> E2X_ORDERS_UN_D93A

3) localejbs/CallSapAdapter

- 0

Does anyone have an idea what I have to change?

Thank you very much for your help!

Best regards,

Peter
