Problem while calling RFC in java

Question

hi,
I writed a java program  calling a batch input RFC.  The RFC return an internal table which storing the system messages of the batch input process. My problem is:
When i debug the java program,the RFC excecuted and return the correct internal table to me.
But when i executed it not in debug mode, there is no batch input messages return to me.
My code is:
package com.hongta.com.z_delivery_bdc;
import com.sap.mw.jco.IFunctionTemplate;
import com.sap.mw.jco.JCO;
import com.sap.mw.jco.JCO.ParameterList;

hi,
i had resolved my problem in other way.I don't upload my data using ws_upload now,but upload with table.
here is my code.Maybe helpful to somebody:
       JCO.Table C_XYORDERTable;
     JCO.Table C_XYORDPR_FINALTable;
     public void getXyordprFinalElement(Element e) {
          try {
               for (Iterator i = e.getChildren().iterator(); i.hasNext();) {
                    Element child = (Element) i.next();
                    if (child.getName().equals("ORDER_ID"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "ORDER_ID");
                    else if (child.getName().equals("ID"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "ID");
                    else if (child.getName().equals("PRODUCT_ID"))
                         C_XYORDPR_FINALTable.setValue(
                              child.getText(),
                              "PRODUCT_ID");
                    else if (child.getName().equals("MATNR"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "MATNR");
                    else if (child.getName().equals("QUANTITY"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "QUANTITY");
               C_XYORDPR_FINALTable.nextRow();
          } catch (Exception ex) {
               ex.printStackTrace();
