retrieving data for a report table

This is in reference to the thread

Business Object Reports with Prompts being called from .NET SDK

I am trying to do the same(i.e I want to retrieve the data for the reports) for a report in table format and I get null pointer exception at myBOView.getContents(). Please find the code below

How to resolve this?

RetrieveData XMLdata = new RetrieveData();

RetrieveXMLView XMLview = new RetrieveXMLView();

XMLdata.setRetrieveView(XMLview);

ViewSupport xmlViewSupport = new ViewSupport();

xmlViewSupport.setOutputFormat(OutputFormatType.XML);

xmlViewSupport.setViewType(ViewType.XML);

xmlViewSupport.setViewMode(ViewModeType.REPORT_PAGE);

RetrieveXMLView retXMLView = new RetrieveXMLView();

retXMLView.setViewSupport(xmlViewSupport);

RetrieveData retBOData = new RetrieveData();

retBOData.setRetrieveView(retXMLView);

Navigate nPage = new NavigateToFirstPage();

Action[] actions = new Action[1];

actions[0] = new Refresh();

RetrieveMustFillInfo retrieveInfo = new RetrieveMustFillInfo();

retrieveInfo.setRetrievePromptsInfo(new RetrievePromptsInfo());

retrieveInfo.setRetrieveQueryContext(new RetrieveQueryContext());

DocumentInformation docInfo = engine.getDocumentInformation("6803", retrieveInfo, null, null, retBOData);

com.businessobjects.dsws.reportengine.XMLView myBOView = (XMLView) docInfo.getView();
