Pentaho報告+ JSF

Question

我想開發一個包含預先設計的pentaho報告的小JSF門戶。我的問題是：如何嵌入pentaho報告以及如何將參數從jsf傳遞到報表引擎。謝謝。

final FacesContext context = FacesContext.getCurrentInstance(); 
ClassicEngineBoot.getInstance().start(); 
try { 
    // load report definition 
    ResourceManager manager = new ResourceManager(); 
    manager.registerDefaults(); 
    manager.registerDefaultLoaders(); 

    ExternalContext extContext = context.getExternalContext(); 

    String reportPath = "file:" + extContext.getRealPath("aaaaaaaaaaaaa.prpt"); 

    Resource res = manager.createDirectly(new URL(reportPath), MasterReport.class); 
    MasterReport report = (MasterReport) res.getResource(); 
    report.getParameterValues().put("x1","%" + current.getx1() +"%"); 
    report.getParameterValues().put("x2","%" + current.getx2() +"%"); 

    HttpServletResponse httpServletResponse = 
    (HttpServletResponse) extContext.getResponse(); 
    httpServletResponse.setContentType("application/rtf"); 
    httpServletResponse.setHeader("Content-Disposition", 
    "attachment; filename=\"bbbbbbbbb.rtf\""); 

    RTFReportUtil.createRTF(report, httpServletResponse.getOutputStream()); 
    FacesContext.getCurrentInstance().responseComplete(); 
} catch (ReportProcessingException ex) { 
}
