We are having web application reports in the application using BO-XI SDK Viewer API. This API approach was working fine earlier. We upgrade our reporting component to SAP BO-4 (Crystal Server 2011) due to EOL of BOXI.
We have updated new API’s provided by SAP as per guide.
We updated web based Crystal Report Viewer (DHTML Viewer). The crystalreportviewer folder coming with SAP CS 2011.
We applied updated patch set upto last patch released CS2011 SP4 Patch4.
We still facing issue while viewing report in DHTML viewer provided by SAP. Please advice on below.
In our web application we do have updated folder for /crystalreportviewer.
We dynamically creating enterprise session object to get client document which explained as below –
IEnterpriseSession es = null;
try{
es = sm.logon(mUser, mPassword, mAPSName, mAuthType);
}catch(Exception e){
// request dispatched to error page
}
// Get the Report Application Factory service from Crystal Enterprise
IReportAppFactory rptAppFactory = (IReportAppFactory)es.getService("", "RASReportService");
// Get the InfoStore service from Crystal Enterprise
IInfoStore infoStore = (IInfoStore)es.getService("", "InfoStore");
IInfoObjects oInfoObjects = infoStore.query(“Select * From CI_INFOOBJECTS…for RPT File.”);
ReportClientDocument clientDoc = rptAppFactory.openDocument((IInfoObject)oInfoObjects.get(0), 0, objLocale);
Setting parameter
// Setting Parameter to clientDoc
Object[] parameters = {
parseDate(fromDate),
parseDate(endDate),
getLanguageID(request),
reportName,
getLanguageID(request)
};
Fields parameterFields = clientDoc.getDataDefController().getDataDefinition().getParameterFields();
for(int index=0; index < parameters.length; index++){
ParameterField oldParameter = (ParameterField)parameterFields.getField(index);
ParameterField newParameter = (ParameterField) oldParameter.clone(true);
newParameter.getCurrentValues().removeAllElements();
ParameterFieldDiscreteValue newDiscreteValueObj = new ParameterFieldDiscreteValue();
newDiscreteValueObj.setValue(parameters[index]);
newParameter.getCurrentValues().add(newDiscreteValueObj);
ParameterFieldController paramController = clientDoc.getDataDefController().getParameterFieldController();
paramController.modify(oldParameter, newParameter);
}
// Create an Viewer
CrystalReportViewer viewer = new CrystalReportViewer();
//Set the name for the interactive viewer
- viewer.setName("Crystal_Report_Viewer");
- viewer.setDisplayPage(true);
//Set Navigation button false
- viewer.setHasHistoryNavigationButtons(false);
//Set best fit to page true
- viewer.setBestFitPage(true);
// Set reuse parameter on referesh
- viewer.setReuseParameterValuesOnRefresh(true);
// Set Own Page true
- viewer.setOwnPage(true);
// Enabled export and print button
- viewer.setHasExportButton(true);
- viewer.setHasPrintButton(true);
// Group Tree Removed
- viewer.setDisplayGroupTree(false);
// Toggle group false
- viewer.setHasToggleGroupTreeButton(false);
//viewer.refresh();
// Removed refersh button
- viewer.setHasRefreshButton(false);
- viewer.setPrintMode(CrPrintMode.ACTIVEX);
// Set the source for the interactive viewer to the client documents report source
- viewer.setReportSource(clientDoc.getReportSource());
// Retain parameter and set again for pagination in viewer
setReportURL(viewer,request);
// Process the http request to view the report
- viewer.processHttpRequest(request, response, getServletConfig().getServletContext(), out);
//response.flushBuffer();
// Close client document
- clientDoc.close();
// Dispose of the viewer object
- viewer.dispose();
- es.logoff();
Issue we faced?
a) On Pagination thorws exception in webreportinglog as
[@APPNAME@] ERROR [[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'] WebReportLogger.error(62) | Unable to set the ancestors
