Hi Pooja,
I am a software developer working in java platform.
I need your help.Can you send me code through which we can display parametrized report using only Crystal Report 9.0 and RAS 9.0.
thanks,
regards,
Arvind

Approximately so:

String par1 = request.getParameter( "par1" );
//
// Initialize server connect
//
ReportAppSession app = new ReportAppSession();
app.setReportAppServer( "admin" );
app.initialize();

ReportClientDocument clientDoc = (ReportClientDocument)app.createService( "com.crystaldecisions.sdk.occa.report.application.ReportClientDocument" );
clientDoc.open( "MyReport.rpt", OpenReportOptions._openAsReadOnly );
CrystalReportViewer viewer = new CrystalReportViewer();
viewer.setReportSource(clientDoc.getReportSource());

viewer.setDisplayPage( true );

String strContent = null;
strContent = viewer.getHtmlContent( request, response, pageContext.getServletContext());

//
// Read parameters
//
Fields fields = viewer.getParameterFields();
ParameterField fld = (ParameterField)fields.getField( 0 );
Values values = fld.getDefaultValues();
ParameterFieldDiscreteValue val = new ParameterFieldDiscreteValue();
val.setValue( par1 );
values.add( 0, val );
fld.setCurrentValues( values );

viewer.setParameterFields( fields );
viewer.processHttpRequest( request, response, pageContext.getServletContext(), pageContext.getOut() );

viewer.dispose();
clientDoc.close();

And all.

My question:
how export report ? Example in RAS SDK 9 not working ! There is a mistake: "OutputStream already retrieved"
What to do ?

Mr. Buba

Hello Pooja Mohan !

I'm use Oracle Container for Java (OC4J) as Application Server and I tried to use JavaViewer in JSP. he conclusion of the report in a browser passes normally, but by pressing button "Export" or "Print" happen invocation same JSP with some parameters. It to lead to to a mistake "OutStream already retrived". If to use servlet that will be all OK.

Instead of JSP I use servlets and all works for me.
