Error: The report source could not be retrieved from the state object.

Question

I have been trying to create a report in a JSF page. The relevant parts are below:
Inside the JSP page, this is the code:
              <jsp:useBean id="MyBean" class="com.nm.facade.rto.POJOViewerBean" scope="session" />
                <jsp:setProperty name="MyBean" property="reportLocation" value="Report1.rpt" />
               <v:reportPageViewer reportSource="#{MyBean.reportSource}"
                                       displayToolbarPrintButton="true"
                                       printMode="ActiveX"
                                       zoomPercentage="100"
                                       displayToolbarExportButton="true"
                                       displayToolbarRefreshButton="true"
                                       viewerName="My Viewer"
               ></v:reportPageViewer>
In the backing bean, this is the relevant code:
    public Object getReportSource() throws ReportSDKException
        if (propertiesChanged || reportSource == null)
            propertiesChanged = false;
            if (reportLocation == null)
                throw new RuntimeException("The reportLocation property must be set before a report source is retrieved");
            ReportClientDocument rcd = new ReportClientDocument();
            rcd.setReportAppServer(ReportClientDocument.inprocConnectionString);
            rcd.open(reportLocation, 0);
            DatabaseController dbc = rcd.getDatabaseController();
            //Create the POJO collection and populate it with data
            ReportData[] data =
              new ReportData("B.B.", "King", 6, new Date(25, 9, 16)),
                new ReportData("Muddy", "Waters", 7, new Date(15, 4, 4)),
                new ReportData("John Lee", "Hooker", 8, new Date(16, 8, 16)),
                new ReportData("Otis", "Rush", 9, new Date(34, 4, 29)),
                new ReportData("Buddy", "Guy", 10, new Date(36, 7, 30))
            //Create the result set from the collection of POJOs
            POJOResultSetFactory factory = new POJOResultSetFactory(ReportData.class);
            factory.setVerbose(true);
            POJOResultSet results = factory.createResultSet(data);
            ResultSetMetaData metaData = results.getMetaData();
            //Set the resultset as the report datasource
                  //Get the table name from the 'Set Datasource Location' dialog in the Crystal Reports designer
            String reportTable = "getReportDataDataSource";
            dbc.setDataSource(results, reportTable, reportTable);       
            IReportSource reportSource = rcd.getReportSource();
            if (reportSource == null)
                throw new RuntimeException("Unable to get a report source.");
        return reportSource;
In the CRConfig.xml, this is what is there:
<?xml version="1.0" encoding="utf-8"?>
<CrystalReportEngine-configuration>
    <reportlocation>../reports</reportlocation>
    <timeout>0</timeout>
    <ExternalFunctionLibraryClassNames>
         <classname></classname>
    </ExternalFunctionLibraryClassNames>
</CrystalReportEngine-configuration>
The report template 'Report1.rpt' is packaged under WEB-INF/reports in the war file.
When I try to generate the report by accessing the JSF page, I am getting an error: "The report source could not be retrieved from the state object. "
I am not sure what is wrong. Can someone help me in resolving this issue?

My formatting gets lost and the message looks unintelligible. After some experimentation, I found that if the message exceeds some length, the formatting is removed. Since I couldn't find any way to delete this post, I made another post with the same subject. Please ignore this post and help me to find a solution for the problem posted in the other thread with the same subject. Thanks in advance.
