You can think of *.rpt as template. When the RAS serve the report to web browser, *.rpt needs to be rendered as a html page. Winthin your jsp page, you can call RAS Jdk to processhtmlrequest

tongcd(不明真相的总是群众)
sample :

rptAppSession = new ReportAppSession();
rptAppSession.initialize();
ReportClientDocument clientDoc =
(ReportClientDocument) rptAppSession.createService("com.crystaldecisions.sdk.occa.report.application.ReportClientDocument");
clientDoc.open("test.rpt", 0);
CrystalReportViewer theViewer = new CrystalReportViewer();
IReportSource reportSource = clientDoc.getReportSource();
theViewer.setReportSource(reportSource);
DataDefController ddc = clientDoc.getDataDefController();
ParameterFieldController pfc = ddc.getParameterFieldController();
pfc.setCurrentValues("", "Para1", new String[]{"value1"});

theViewer.processHttpRequest(request, response, getServletConfig().getServletContext(), out);

      • 生成的jsp上,defaultly,有没有那些控件:next page,last page, page of pages... -cathy618(cathy); 2003-7-2 (#1267373@0)
        • you can optionally chose what to display, as you can see from code inside, you can specify -tongcd(不明真相的总是群众); 2003-7-2 {757} (#1267468@0)
          theViewer.setHasRefreshButton(true);
          theViewer.setDisplayPage(true);
          theViewer.setDisplayGroupTree(false);
          theViewer.setDisplayToolbar(true);
          theViewer.setHasSearchButton(false);
          theViewer.setHasRefreshButton(false);
          theViewer.setHasPrintButton(true);
          theViewer.setHasExportButton(true);
          theViewer.setHasGotoPageButton(true);
          theViewer.setHasZoomFactorList(false);
          theViewer.setHasViewList(false);
          theViewer.setHasLogo(false);
          theViewer.setEnableDrillDown(false);

          next/prev page button can be set by code. But page of pages need to be done in 'speical fields' in report designer.

          My suggestion is to setup an environment and get hands dirty. You will find the answer in mintues
          • 多谢能否给一个sample,用Html或jsp把rpt 通过activevX 显示在browser里(不是纯HTML).crystal report9不支持URL reporting,又不想用CE9. -cathy618(cathy); 2003-7-7 (#1274084@0)
