How to set Database Logon Info, if allowDatabaseLogonPrompting="false"

Question

Hey,
Here is the Version Details -
Crystal report X1 R1
Sql Server 2005
Tomcat 5.5.27
Question -
I am using jsf viewer to dispaly report in my web project. We don't want to prompt for database logon information before showing the report to teh front user. I have seen few sample jsp code which creates the crystalreportviewer object and set the connectioninfo details and calls the processhttprequest method to render the report. I have tried the same approach and it works for us.
But our requirement is to just use the jsf tags. Is there a way to pass the database credentials to the jsp without prompting for Logon Information or using the java code to populate the connectioninfo in crystalreportviewer instance.
Here is the jsp file -
<%@ taglib uri="/crystal-tags-reportviewer.tld" prefix="crviewer" %>
<crviewer:viewer displayGroupTree="false" viewerName="CrystalViewer"
reportSourceType="reportingComponent"
displayGroupTree="false"       
        displayToolbarExportButton="true"
        displayToolbarPrintButton="true"
        displayToolbarRefreshButton="true"
        displayToolbarToggleTreeButton="false"
        displayToolbarCrystalLogo="true"
top="100"
left="200"
reportSourceVar="#{Report.reportSource}"
isOwnPage="true"
displayGroupTree="false"
allowDatabaseLogonPrompting="false">
<crviewer:report reportName="Report.rpt">
     <crviewer:partsViewer viewerName="CrystalViewer"
          reportSourceType="reportingComponent"
          title="Fill to Fill Report"
          numberOfRecords="10"
          showHeadings="true"
          showPageNavigationLinks="true"
          allowParameterPrompting="false"
          reportSourceVar="#{Report.reportSource}"/>
</crviewer:report>
</crviewer:viewer>
I am trying to run this and it shows an error page with information Database Login Error.
I have created the report using JDBC/JNDI database connection with trusted authentication = false.
The Sql Server 2005 error log shows -
Error: 18456, Severity: 14, State: 5.
Logon       Login failed for user ''. [CLIENT: <named pipe>]
Any help will really be appreciated.
Thanks

Yes within the report designer i am able to refresh the report and open and close the report without getting prompted. I am not changing any database properties at runtime and using the jar files which come with CR Release 2.
All i am doing is to export the report in pdf format. Here is the code :
ReportExportControl exportControl = new ReportExportControl();
ExportOptions exportOptions = new ExportOptions();
PDFExportFormatOptions  pdfOptions = new PDFExportFormatOptions();
exportOptions.setExportFormatType(ReportExportFormat.PDF);                 
exportOptions.setFormatOptions(pdfOptions);     
exportControl.setExportOptions(exportOptions);
exportControl.setExportAsAttachment(false);     
exportControl.setReportSource(this.wrapper.getReportSource());
exportControl.setName(this.wrapper.getReportName());
exportControl.setEnableLogonPrompt(false);
//Pass Fields object to ReportExportControl
exportControl.setParameterFields(this.wrapper.getFields());
//Export only works if i pass the connections object with connectioninfo object populated with username and password.
//We want to run the report using trusted authentication i.e. we don't want to pass username and password.
exportControl.setDatabaseLogonInfos(connections);               
if(to_refresh)
  exportControl.refresh();
If i don't provide the connectioninfo object with proper username and password to run the report inside the java class, it try's to logon to database using username = 'userid'. I think it picks it from the JDBC Connection String created while creating database connection for the report in the designer.
Here is the jdbc connection string for the JDBC/JNDI connection created inside the report designer:
!net.sourceforge.jtds.jdbc.Driver!jdbc:jtds:sqlserver://localhost:1433/customer;namedPipe=true!user=!password=.
Is there a way to get pass this problem??? Is there a way to force the connection from the java class to use trusted authetication??? Can we change the connection string to replace the userid with empty string to force trusted authetication???
Any help will be really appreciated.
