- java handling ABAP Exception

Question

Hi folks,
I am developing a webdynpro java programm that communicate with R/3 through a RFC.
In an especif condition the ABAP program raises an "NO_DATA_FOUND" exception.
Unfortunatelly  I can't catch this exception raised by ABAP.
Do you may help me?
Best wishes,

Hi Nelson,
You will get the error "NO_DATA_FOUND" in the back end when there are no records and you will get "INVALID_DATA"  when you pass an invalid input.
BAPIRET2 structure return the error/warning/success messages if there are in the in the backend. If they are returning any messages for the above errors then you can print those messages by accessing the BAPIRET2 structure.
You can print different error/warning/success using the return structure (if they are returning any)with the following code.
IWDMessageManager msgmgr = wdComponentAPI.getMessageManager();
     String msgtype = new String();          
     try{
//          If the RFc is returning any error messages the display those messages
     if(wdContext.currentReturn_outElement().getMessage()!=null){
          for(int i=0; i<wdContext.node<Return_out()>.size();i++)
               msgtype = wdContext.nodeReturn_out().getElementAt(i).getAttributeValue("Type").toString();
               if(msgtype.equals("W"))
                    msgmgr.reportWarning(wdContext.currentReturn_outElement().getMessage());
               else if(msgtype.equals("E"))
                    msgmgr.reportException(wdContext.currentReturn_outElement().getMessage(),true);
               else
                    msgmgr.reportSuccess(wdContext.currentReturn_outElement().getMessage());
     }catch(Exception e){
Or
int size = wdContext.node<Return_out()>.size();
if(size ==0){
  //here you can print your own message
