JCo - Unicode issue


Recently, we migrated SAP to unicode version. Due to this, we are getting the below error when we try to connect from SapJCo to SAP. The version of JCo used is 2.1.6. SAP is hosted on Unix and Java applications are hosted on Windows. We tried with jco.client.codepage= 4103; we are getting different error(RFC_ERROR_LOGON_FAILURE: >> unknown RFC error, no error log found <<) when we give the codepage property.

Please let us know how to resolve the below issue:

Exception in thread "main" Conversion error between two character sets., error key: RFC_ERROR_SYSTEM_FAILURE


At the SAP side, we are getting the below errors

Error analysis

The error probably occurred when installing the

R/3 system.

The termination was triggered in function "RfcExtendedReceive"

of the SAP kernel, in line 301 of the module


The internal operation just processed is "FUNC".

Internal mode was started at 20101124144800.

    This got resolved.

    We had to make changes to the XML which is embedded in the java code of R3Connector classes. Changed the encoding type and data types in the XML. It went through.
