JCO exception BaseProxyException error key: RFC_ERROR_SYSTEM_FAILURE



I am trying to oconnect up to a SAP system when running the tutorial "Using Generated Proxies to Call Function Modules" in the "SAP Web AS for Java Applications" guide.

The call jcoclient.connect();

works fine, and I see the user logged on in the SAP system. However the call to

Bapi_Flight_Getlist_Output output = myproxy.bapi_Flight_Getlist(input);

Causes an exception to be thrown of the type described above.

I am unable to see any evidence of RFC activity on the SAP side in the RFC trace files or system log; there are no system dumps, system log shows no problems.

All I can think of is that the RFC connection is not correctly configured on the R/3 side. Anybody have any experience of this?
