JCO$Exception: (120) JCO_: JCO.Server could not unmarshall import parameter

[Former Member]

Hi Everybody,

I'm using SAP JCO and when SAP sends some dates to my Java program I got the Exception bellow:

Exception com.sap.mw.jco.JCO$Exception: (120) JCO_: JCO.Server could not unmarshall import parameters

at com.sap.mw.jco.rfc.MiddlewareRFC$Server.nativeListen(Native Method)

at com.sap.mw.jco.rfc.MiddlewareRFC$Server.listen(MiddlewareRFC.java:1395)

at com.sap.mw.jco.JCO$Server.listen(JCO.java:7067)

at com.sap.mw.jco.JCO$Server.run(JCO.java:6996)

at java.lang.Thread.run(Thread.java:619)

Anybody knows what could happened?

I try to found some solution on the internet but I found nothing.

Thanks for any help.

Hi danielpaulin ,

When attempting to unmarshal data flows using an encoding other than UTF-8, such as

UTF-16, then you must also call the setUnmarshalEncoding method to specify this

encoding. This enables the eWay to properly unmarshal the byte array.

Hope may get some input.
