HTML generated by backing bean

[Juri Gavrilenko]

Hi everybody,

I've got following problem, that maybe is pretty easy to solve, but I'm not good in web-tier. I have reporting components (Jasper) and I've integrated it into JSF using backing bean, that generates report. This bean itself obtains objects from the servlet API (implementation: JSF and Jasper).
The problem is, how can I integrate this bean, so that the report is being showed in my navigation structure, e.g. that I can generate the html on the same JSF-page. Currently completely new page is being generated (in the same window) and I have no ideas how I can use it with my template.

The HTML code is:

 <ui:composition template="/templates/main.xhtml">
<ui:define name="title">Parts Orders Report</ui:define>
<ui:define name="current">panel</ui:define>
<ui:define name="body">
 
<h:selectOneRadio value="#{reportingBean.exportOption}">
<f:selectItem itemValue="PDF" itemLabel="PDF"/>
<f:selectItem itemValue="HTML" itemLabel="HTML"/>
<f:selectItem itemValue="EXCEL" itemLabel="EXCEL"/>
<f:selectItem itemValue="RTF" itemLabel="RTF"/>
</h:selectOneRadio>
<h:commandButton  action="#{reportingBean.execute}" value="Get Report" />
</ui:define>
</ui:composition>   

The bean code is:

 
  protected void prepareReport() throws JRException, IOException {
    ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
    
    ServletContext context = (ServletContext) externalContext.getContext();
    HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();
    HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
    
    ReportConfigUtil.compileReport(context, getCompileDir(), getCompileFileName());
    
    File reportFile = new File(ReportConfigUtil.getJasperFilePath(context, getCompileDir(), getCompileFileName()+".jasper"));
    
    JasperPrint jasperPrint = ReportConfigUtil.fillReport(reportFile, getReportParameters(), getJRDataSource());
    
    if(getExportOption().equals(ExportOption.HTML)) {
      ReportConfigUtil.exportReportAsHtml(jasperPrint, response.getWriter());
    }else {    
      request.getSession().setAttribute(BaseHttpServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jasperPrint);    
      response.sendRedirect(request.getContextPath()+"/servlets/report/"+getExportOption());
    }
    
    FacesContext.getCurrentInstance().responseComplete();
  }
