Zunxian,
The error message "Invalid request., error key: RFC_ERROR_SYSTEM_FAILURE" makes it seem like there's something wrong with the request. You generally get an error message of the group  RFC_ERROR_SYSTEM_FAILURE when there's something wrong with the backend system, or when you send a request that makes it dump.
What Bapi/RFM are you trying to call?
have a look at <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/f6/daea401675752ae10000000a155106/content.htm">this explaination of different JCO Exceptions</a> for more information.
