How to pass parameter values to a report befor schedule it?

Question

I tried to use Business Objects web service to schedule a report. But I failed to pass in any parameter values. The report was able to run successfully. But check all history from Infoview, all parameter are with NULL value. Does anybody encounter the same problem and has good resolution for this? Many thanks.
Here's my code:
// Logon Crystal Report Server
LogonCrystalServer();
// Find Report
GetOptions oGetOptions = new GetOptions();
oGetOptions.IncludeSecurity = false;
ResponseHolder rh = _bipService.Get("cuid://<" + reportCuid + ">@SI_SCHEDULEINFO, SI_PROCESSINFO", oGetOptions);
InfoObjects oInfoObjects = rh.InfoObjects;
if (oInfoObjects == null || oInfoObjects.InfoObject == null) return;
// Set Scheduling Info
CrystalReport oReport = (CrystalReport)oInfoObjects.InfoObject[0];
oReport.Name = oInfoObjects.InfoObject[0].Name;
SchedulingInfo oSchedulingInfo = oReport.SchedulingInfo;
oSchedulingInfo.RightNow = true;
oSchedulingInfo.ScheduleType = (ScheduleTypeEnum.ONCE);
oReport.SchedulingInfo = oSchedulingInfo; 
// Set Format Info.
ReportProcessingInfo procInfo = oReport.PluginProcessingInterface;
CrystalReportFormatOptions repFormat = new CrystalReportFormatOptions();
repFormat.Format = ReportFormatEnum.EXCEL;
repFormat.FormatSpecified = true;
repFormat.UseExportOptionsInReport = true;
repFormat.UseExportOptionsInReportSpecified = true;
procInfo.ReportFormatOptions = repFormat;
// Get Report Parameters and Set their values
// I don't know if the step has any problem. I copied from wssdk sample.
ReportParameter[] repParams = procInfo.ReportParameters;           
for (int i = 0; i < repParams.Length; i++)
    CurrentValues oCurrentValues = new CurrentValues();
    BusinessObjects.DSWS.BIPlatform.Desktop.PromptValue[] oPromptValue = new BusinessObjects.DSWS.BIPlatform.Desktop.PromptValue[1];
    oPromptValue[0] = new BusinessObjects.DSWS.BIPlatform.Desktop.PromptValue();
    oPromptValue[0].Data = "Test";
    oCurrentValues.CurrentValue = oPromptValue;
    repParams<i>.CurrentValues = oCurrentValues;
procInfo.ReportParameters = repParams;       
oReport.PluginProcessingInterface = procInfo;
// Schedule run the report   
InfoObjects infoObjects = _bipService.Schedule(oInfoObjects);
//Get new instance id
string instanceCuid = infoObjects.InfoObject[0].NewJobID;

Answer 1

Can you clarify your scenario? Which is the case you're talking about?
1) You want to pass a parameter from OmniPortlet to a PL/SQL procedure.
2) You want to pass a parameter from a PL/SQL procedure to OmniPortlet.
In both cases the most obvious way of doing it is through request (URL) parameters.
Render a link in your portlet (either in OmniPortlet or using PL/SQL) that invokes a portal page, containing the other portlet.
Both OmniPortlet and PL/SQL allow you to wire and access page parameters.
Take a look at the Using Parameter and Events section of the Portal User's Guide and the Parameters and Events section of the Portal Developer's Guide.
Hope this helps,
