I follow this guide: Using an Adaptive RFC 2 Model in Web Dynpro for Java(Using an Adaptive RFC 2 Model in Web Dynpro for... | SCN) to excute ARFC2
BAPI_FLIGHT_GETLIST like this:
-------------------------
public void wdDoInit() {
//@@begin wdDoInit()
// Set the class wide reference to the component's message manager
msgMgr = wdComponentAPI.getMessageManager();
// Create a new model
flightModel = new FlightModel();
// Using the model, create an executable model object for the BAPI
bapiGetFlightList = new Bapi_Flight_Getlist_Input(flightModel);
}
--------------------------------
public void call_BAPI_FLIGHT_GETLIST( ) {
//@@begin call_BAPI_FLIGHT_GETLIST()
// Call BAPI_FLIGHT_GETLIST by using the class wide reference to the
// model object. This style of coding makes the coding easier to
// understand, and bypasses the need to traverse the context to locate
// the node to which the model object is bound, and then finally call
// execute() method. It is much simpler to invoke the execute() method
// directly on the model object
try {
bapiGetFlightList.execute();
// In ARFC2, it is no longer necessary to call the invalidate()
// method of the context node that corresponds to the output side of
// the BAPI's interface
checkBapiReturn(bapiGetFlightList.getOutput().getReturn());
}
catch(ARFC2ModelExecuteException ex) {
// If the call to the ABAP system goes pear-shaped, then the most
// meaningful message to show the user is usually found by calling the
// exception object's getNestedLocalizedMessage() method
msgMgr.reportException(ex.getNestedLocalizedMessage());
// Also write the exception to the system log
// Please make it a habit to add this simple line of code because it
// makes solving CSN messages *so* much easier!
logger.catching(ex);
}
//@@end
}
-----------------------
public void checkBapiReturn( java.util.List returnStruct ) {
//@@begin checkBapiReturn()
// Check that we've actually got a return value here
if (!returnStruct.isEmpty()) {
Bapiret2 returnMsg;
// Process all the messages found in the return structure
for (int i = 0; i < returnStruct.size(); i++) {
returnMsg = (Bapiret2)returnStruct.get(i);
// What king of message was returned?
switch(returnMsg.getType().toCharArray()[0]) {
// Error
case 'E':
msgMgr.reportException(returnMsg.getMessage());
break;
// Warning
case 'W':
msgMgr.reportWarning(returnMsg.getMessage());

case 'I':

// Something else...
default:

" with text " + returnMsg.getMessage());
}
}
}

//@@end

//@@begin others

//@@end
------------------------------------------------
when I execute rfc output-Flight_List is null in table UI
but When I set external breakpoint to debug in ecc I find output-Flight_List is not null
I know about it in netweaver 7.0 but 7.3 or 7.4 is different
can anybody help me to solve this issue..
thanks
