At Invoke of: Update,A COM exception has been encountered

Question

Hi Guys,
I just use java to access the data of SAP B1, and I  met a trouble, I have no idea.
I have imported into SAP B1 from file and export the SAP data to a file, just in business partner module,
it's ok.
I also can export data from ORDR of SAP B1 database to  a file.
But I can't work out importing data from external data about Order module, just table ORDR.
I have search the WEB for 2 days, just nothing!!
I will appreciate to your great help. Could you please give me a sample, should be perfect!!!!

the following just is some code.
          ICompany vCompany = SapSdkHelper.getICompany();
          vCompany.connect();
          IDocuments aOrder = SBOCOMUtil.newDocuments(vCompany,
                    SBOCOMConstants.BoObjectTypes_Document_oOrders);
          IDocument_Lines line = aOrder.getLines();//line should be the data in table rdr1
          int successCount = 0;
          for (String[] rowData : dataList) {
               Integer key = new Integer(rowData[0]);
               if (aOrder.getByKey(key)) {
                    aOrder.setAddress(aOrder.getAddress()+"test");
                    int rr = aOrder.update();
                    SBOErrorMessage errMsg = vCompany.getLastError();
                    System.out.println(errMsg.getErrorMessage());
                    System.out.println(rr);
                    continue;
               aOrder.setDocNum(key);
                                                aOrder.setCardCode(rowData[2]);
               aOrder.setCardName(rowData[3]);
               aOrder.setDocTotal(Double.valueOf(rowData[4]));
               aOrder.setDocType(SBOCOMConstants.BoDocumentTypes_dDocument_Items);
               //aOrder.setDocCurrency("RMB");
               //aOrder.setDocRate(10.1);
               line.setItemCode("A00001");
               line.setItemDescription("description Testing");
               line.setQuantity(new Double(3));
               line.setPrice(new Double(3));
               //line.setRate(10.1);
               //line.setCurrency("RMB");
               //line.add();
               long rc = aOrder.add();
               SBOErrorMessage errMsg = vCompany.getLastError();
               System.out.println(errMsg.getErrorMessage());
               System.out.println(rc);
               successCount++;
          vCompany.disconnect();

Just refer to DI JCo: Getting a COM Exception when adding an Order
I got it.
If you have any question about this issue, please contact me.
For SAP B1, just need to patch java.exe, if you develop/test something in IDE you should also patch javaw.exe, please notice the right path used in IDE.
Just my steps-
1. download the Visual studio express 2008 from microsoft.com and install it online(no need to download SQLSERVER Express)
2. backup the original exe file, java.exe/javaw.exe
3. edit the PATH environment variable plus 'C:Program FilesMicrosoft Visual Studio 9.0VC in'
4. open CMD window and enter into %JAVA_HOME%/bin/
5. Use dumpbin.exe to check the original stack size
    dumpbin.exe /headers java.exe
    find line: 40000 size of stack reserve
    It means the current stack size is 256k
6. Use editbin.exe to patch the exe, for example with 2m stack size
    2m = 2 * 1024 *1024 bytes = 2097152 bytes
    editbin.exe /stack:2097152 javaw.exe
7. Use dumpbin.exe to verify the patch.
   dumpbin.exe /headers java.exe
   dumpbin.exe /headers javaw.exe
   find line: 200000 size of stack reserve
   It means the current stack size is 2m
IT'S OKAYYYYYY.
The version of SAP B1 is 7.10.32 SP:00 EF:2.
The version of SDK just is contained in the SAP B1.
Hope it can help you a little.
