error:exportername is empty

[mickey]

Hi Frends,
I have a very basic simple question.

I want to show crystal reports (exported in excel format)
using JSP page on tomcat with mysql as a database.

I downloaded crystal report 11 evaluation version but not crystal report server.

I wrote a jsp code to export the report in excel format.
but tomcat is showing no report but

ERROR: exporterName is empty

I am stuck in this.
I am attaching my jsp code for reference.
May be I am missing something very important.

<@ page import= "com.crystaldecisions.report.web.viewer.*,com.crystaldecisions.sdk.occa.report.data.*,
com.crystaldecisions.reports.reportengineinterface.JPEReportSourceFactory,
com.crystaldecisions.sdk.occa.report.reportsource.IReportSourceFactory2,
com.crystaldecisions.sdk.occa.report.exportoptions.ReportExportFormat,
com.crystaldecisions.sdk.occa.report.exportoptions.*,
com.crystaldecisions.report.web.ServerControl,


com.crystaldecisions.sdk.occa.report.reportsource.IReportSource"
%lt String path = "/Report2.rpt";
IReportSourceFactory2 rsf = new JPEReportSourceFactory();
IReportSource rptSource = (IReportSource)rsf.createReportSource(path,
request.getLocale());

ConnectionInfos connInfos = new ConnectionInfos();
IConnectionInfo connInfo1 = new ConnectionInfo();
connInfo1.setUserName("root");
connInfo1.setPassword("ragini");
connInfos.add(connInfo1);
CrystalReportViewer viewer = new CrystalReportViewer();
viewer.setDatabaseLogonInfos(connInfos);
viewer.setReportSource(rptSource);
viewer.setEnableLogonPrompt(false);
viewer.setName("CrystalReportViewer");
ReportExportControl exportcontrol=new ReportExportControl();
ExportOptions oExportOptions = new ExportOptions();
oExportOptions.setExportFormatType(ReportExportFormat.MSExcel);

ExcelExportFormatOptions xlOpts = new ExcelExportFormatOptions();
oExportOptions.setFormatOptions(xlOpts);

exportcontrol.setReportSource(rptSource);
exportcontrol.setExportOptions(oExportOptions);
exportcontrol.setName("ReportExportCintrol");

exportcontrol.processHttpRequest(request, response, getServletConfig().getServletContext(),
out);

should I need to do some changes in server.xml of tomcat5.5
Should I need some another component of Crystal reports to serve the web based reports.

Please help me.

"mickey",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!
