Problem Generating a Report by passing a Resultset as a datasource

Question

I am having troubles generating a report using CR for Eclipse 2.0.
I used the example that shows how do a simple select SQL query to the database and pass the resultset from the query to the report to generate a report from here: https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/201084dc-be66-2b10-64bf-dde4970c9b90
I used a simple rpt file that simply shows the content of two columns from a table: TXN_TYPE_CD and TXN_STATUS_CD from a POLICY_TXN table.
Using the code above, and just modifying it a bit to include my jdbc connection details as well as my select query, I was able to view the report which populated data from my database (Oracle 10g) at runtime of the application.  This test proved positive.
However, the problem I am having is that I am trying to make this code into a Servlet for use in a Java EE application running on Websphere 6.1.0.17 using JVM 1.5.0_15  64-bit.  Instead of using the DHTML thick client, I export to PDF.  When I do this, the crystal report shows as a PDF, but the data is missing for some reason.  Only the headers for the two db columns are shown.  I don't see any startling differences between the code and am 100% positive that my resultset is being returned with data (I output the data returned in the result set as shown in the code).
Here is the code I am using:
public class CrystalReportGeneratorServlet_WOW extends Servlet {
     private static final long serialVersionUID = 768970549082466125L;
     protected HttpSession session;
     private final String EXPORT_FILE = "myExportedReport.pdf";
     private final String CUSTOM_PATH = "/custom/resource/crystalReport/";
     private String REPORT_NAME;
     public void service(HttpServletRequest request, HttpServletResponse response)
               throws IOException, ServletException {
          Properties loParms = new Properties();
          ResultSet resultSet = null;
          //Obtain current JDBC Connection
          Connection loConn = AppEnvironment.getJDBCConnection();
          Statement statement = null;
          try {
               REPORT_NAME = "Test.rpt";
               //Open report
               ReportClientDocument reportClientDoc = new ReportClientDocument();
               reportClientDoc.open(SystemConfig.getAppHome() + CUSTOM_PATH + REPORT_NAME, 0);
               //Create SQL query.    
               String query = "SELECT \"POLICY_TXN\".\"TXN_TYPE_CD\", \"POLICY_TXN\".\"TXN_STATUS_CD\"" + "FROM   \"POLICY_TXN\"";
               //Query database and obtain the Resultset that will be pushed into the report.  
               statement = loConn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
               //Execute query and return result set.
               resultSet = statement.executeQuery(query);
               //Look up existing table in the report to set the datasource for and obtain its alias.  This table must
               //have the same schema as the Resultset that is being pushed in at runtime.  The table could be created
               //from a Field Definition File, a Command Object, or regular database table.  As long the Resultset
               //schema has the same field names and types, then the Resultset can be used as the datasource for the table.
               String tableAlias = reportClientDoc.getDatabaseController().getDatabase().getTables().getTable(0).getAlias();
               /////TESTING: OUTPUT contents of resultSet
               while (resultSet.next()) {
                    System.out.println("TXN_STATUS_CD = " + resultSet.getString("TXN_STATUS_CD"));
                    System.out.println("TXN_TYPE_CD = " + resultSet.getString("TXN_TYPE_CD"));
               //Push the Java ResultSet into the report.  This will then be the datasource of the report.
               DatabaseController dbc = reportClientDoc.getDatabaseController();
               dbc.setDataSource(resultSet, tableAlias , "resultsetTable");
               //Export to PDF
               ExportToPDF(reportClientDoc, response);
          catch(ReportSDKException ex) {     
               System.out.println(ex);
          catch(Exception ex) {
               System.out.println(ex);               
          } finally {
               try {
                    resultSet.close();
               } catch (SQLException e) {
                         e.printStackTrace();
                    } finally {
                         AppEnvironment.returnStatement(statement);
                         AppEnvironment.returnConnection ( loConn ) ;
     private void ExportToPDF(ReportClientDocument rcd, HttpServletResponse response)
          try {
               ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)rcd.getPrintOutputController().export(ReportExportFormat.PDF);
               rcd.close();
               writeToBrowser(byteArrayInputStream, response, "application/pdf", EXPORT_FILE);
          catch(ReportSDKException ex) {
               System.out.println(ex);
          catch(Exception ex) {
               System.out.println(ex);
     * Utility method that demonstrates how to write an input stream to the server's local file system.
     private void writeToBrowser(ByteArrayInputStream byteArrayInputStream, HttpServletResponse response, String mimetype, String exportFile) throws Exception {
          //Create a byte[] the same size as the exported ByteArrayInputStream.
          byte[] buffer = new byte[byteArrayInputStream.available()];
          int bytesRead = 0;
          try{
               //Set response headers to indicate mime type and inline file.
               response.setHeader("Content-disposition", "inline;filename=" + exportFile);
               response.setContentType(mimetype);
               //Stream the byte array to the client.
               while((bytesRead = byteArrayInputStream.read(buffer)) != -1) {
               response.getOutputStream().write(buffer, 0, bytesRead);
               //Flush and close the output stream.
               response.getOutputStream().flush();
               response.getOutputStream().close();
          } catch (Exception e){
                    e.printStackTrace();
     public static Servlet getInstance()
        return new CrystalReportGeneratorServlet_WOW();
Any help would greatly be appreciated.

Actually Uzair I came across this thread in trying to find a resolution to my problem.  I was wondering if you were able to resolve this issue as it appears as though I may have the same problem.
Thanks.
