Issue while exporting report in Excel Format

Question

Hello,
I am facing problem while exporting the report in Excel Format. After analysis, I think that it could be due to two reasons, either we are using wrong versions of Jars, or we are using wrong API. Here is the code, approaches and problems we are facing. Please help.
First approach we are using is:
// using basic API
import com.crystaldecisions.reports.sdk.ReportClientDocument;
// get client document from crystal report API and open the report by specifying the report name, with path
               ReportClientDocument reportClientDoc = new ReportClientDocument();
               reportClientDoc.open( reportPath, 0 );
               // give chance to extending classes to configure the report document by POJO or by sql parameter etc, just adding the parameters infromation using ParameterFieldController
               configureReportDocument( reportClientDoc, reportMetadata, reportData, reportContext );
               // get data source of crystal report
               Object reportSource = reportClientDoc.getReportSource();
               // export the data - we have also tried with MSExcel format
               ReportExportFormat exportFormat =  ReportExportFormat.recordToMSExcel;
               LOGGER.debug( "exportFormat[" + exportFormat + "]" );
               ByteArrayInputStream byteArray = (ByteArrayInputStream) reportClientDoc.getPrintOutputController().export(
                         exportFormat );
Problem Faced: Specified Excel format is not supported.
Second Approach: We come to know that excel format is supported with new releases and with occa package.
Then we tried with import com.crystaldecisions.sdk.occa.report.application.ReportClientDocument; It ask to set the ReportServer. When we are trying to set the server as
               reportClientDoc.setReportAppServer(ReportClientDocument.inprocConnectionString);
Application is unable to find 'ReportClientDocument.inprocConnectionString' property. It seems like we are using some old jars. However we have downloaded the latest released jars for eclipse 2.
Please help for it. Issue is to export the report in excel format, which is currently working fine for PDF. If this problem is related to Jars, please suggest the path to download the latest jars. We also looking for the latest jars like rasapp and rascore etc. But these are not available with Crystal Report for Eclipse 2 release.
Waiting for urgent help. Thanks you..
Regards,
Mohit

Hi,
Send me Environment Details .
Here is the code  snippet for exporting report to excel format:

String Authen ="secEnterprise";
     //connecting to Enterprise
     IEnterpriseSession es = CrystalEnterprise.getSessionMgr().logon(username,password,cmsname,Authen);
     //get the report App Factory form the Crystal Enterprise
     IReportAppFactory appFactory = (IReportAppFactory) es.getService("","RASReportService");
     //get the infostore service form the Crystal Enterprise
     IInfoStore istore = (IInfoStore) es.getService("","InfoStore");
     //get the report by name from crystal Enterprise
     IInfoObjects iobjects = istore.query("Select * From CI_INFOOBJECTS Where SI_NAME = 'sampleramz2.rpt' and SI_INSTANCE = 0 ");
     //open the report in the report doc object.
     ReportClientDocument Doc = appFactory.openDocument((IInfoObject)iobjects.get(0), 0, Locale.ENGLISH);
     // WORKING WITH THE PRINT OUTPUT CONTROLLER
     //Use the report documents PrintOutputController to export the report to a ByteArrayInputStream
     ByteArrayInputStream byteIS = (ByteArrayInputStream)Doc.getPrintOutputController().export(ReportExportFormat.recordToMSExcel);
     // EXPORTING THE REPORT
     //Create a byte[] (same size as the exported ByteArrayInputStream)
     byte[] buf = new byte[2000 * 1024];
     int nRead = 0;
     //Set response headers to indicate pdf MIME type and inline file
     response.reset();
     response.setHeader("Content-disposition", "inline;filename=ramz");
     response.setContentType("application/xls");
     //Send the Byte Array to the Client
     while ((nRead = byteIS.read(buf)) != -1)
          response.getOutputStream().write(buf, 0, nRead);
     //Flush the output stream
     response.getOutputStream().flush();
     //Close the output stream
     response.getOutputStream().close();

Let me know any information is needed,
