我目前正在使用 Icefaces 1.8.2、JSF 1.1、JasperReports 4.5.1 和 weblogic 10.3.2 我尝试在单击 excel 图像时创建一个功能，它将尝试使用 Jasper Report 将结果获取到 excel 文件中。我可以编译以下代码。

public String downloadToExcel(javax.faces.event.ActionEvent event)
{
    InputStream reportStream = null;
    try
    {

        FacesContext context = FacesContext.getCurrentInstance();  
        ExternalContext ext = context.getExternalContext();  
        //reportStream = ext.getResourceAsStream("resources/jasper/PreviousBookings.jasper"); 
        reportStream = JRLoader.getResourceInputStream("resources/jasper/PreviousBookings.jasper");
        //JasperReport jasperReport = JasperCompileManager.compileReport(fis);
        Object[] previousBooking = new Object[newOpportunityByPreviousBookingDTOList.size()];
        int i = 0;
        for(NewOpportunityDTO previousBookingDTO:newOpportunityByPreviousBookingDTOList)
        {
            previousBooking[i] = previousBookingDTO;
            i++;
        }

        /*
        reportStream = JRLoader.getResourceInputStream("resources/jasper/PreviousBookings.jasper");
        JasperPrint jprint1 = JasperFillManager.fillReport(reportStream, new HashMap(), new JRBeanArrayDataSource(previousBooking));
        JRXlsxExporter exporterXLS = new JRXlsxExporter();
        exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, jprint1);
        exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_FILE_NAME, "c:/test1/test.xlsx");
        exporterXLS.exportReport();
        */
        JasperPrint jasperPrint = JasperFillManager.fillReport(reportStream, new HashMap(), new JRBeanArrayDataSource(previousBooking)); 
        HttpServletResponse resp = (HttpServletResponse) ext  
                .getResponse();  

        resp.setContentType("application/vnd.ms-excel");  
        String filename = new StringBuffer("previousBookings").append(  
                ".xls").toString();  
        resp.setHeader("Content-Disposition", "inline;filename="  
                + filename);  

        JExcelApiExporter exporterXLS = new JExcelApiExporter();  

        exporterXLS.setParameter(  
            JRXlsExporterParameter.JASPER_PRINT,  
            jasperPrint);  
        exporterXLS.setParameter(  
            JRXlsExporterParameter.IS_DETECT_CELL_TYPE,  
            Boolean.TRUE);  
        exporterXLS.setParameter(  
            JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND,  
            Boolean.FALSE);  
        exporterXLS.setParameter(  
            JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,  
            Boolean.TRUE);  
        exporterXLS.setParameter(  
            JRXlsExporterParameter  
                .IS_REMOVE_EMPTY_SPACE_BETWEEN_COLUMNS,  
            Boolean.TRUE);  
         exporterXLS.setParameter(  
        JRXlsExporterParameter.IS_IGNORE_CELL_BORDER,  
         Boolean.TRUE);  
        exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, 
                resp.getOutputStream());  
        exporterXLS.exportReport();
        //byte[] reportPDF = JasperRunManager.runReportToPdf(reportStream, parameterMap, connection); 

        //context.getApplication().getStateManager().saveView(context);  
        context.getApplication().getStateManager().saveSerializedView(context);  
        ServletOutputStream out;
        out = resp.getOutputStream();

        BufferedOutputStream bos = new BufferedOutputStream(out);
        bos.flush();
        bos.close();

        context.responseComplete();  

    }
    catch(Exception e)
    {
        Utility.setTab(AirFreightConstants.AIRFREIGHT_OPPORTUNITIES);
        log.error(StringUtil.exceptionToString(e));
        setErrorMessage("operation.failed.error.message", "Error Detail:"+StringUtil.exceptionToString(e));
        return null;
    }
    return "success";
}

我尝试使用“saveView”，但出现以下错误：

Caused By: java.lang.NoSuchMethodError: javax.faces.application.StateManager.saveView(Ljavax/faces/context/FacesContext;)Ljava/lang/Object;
    at com.cta.web.beans.OpportunitiesBean.downloadToExcel(OpportunitiesBean.java:321)

所以从下面的 url (https://jira.springsource.org/browse/SWF-1112) 它告诉我使用 saveSerializedView 我可以编译但是在执行时得到以下错误：

该方法是在 JSF 1.2 中引入的，因此在 JSF 1.1 中不可用。您需要升级 WebLogic 以使用 JSF 1.2 并重新声明faces-config.xml您的 webapp 符​​合 JSF 1.2 规范。

与具体问题无关，此时需要保存 JSF 视图是很奇怪的。它不会像您想象的那样包含生成的 Jasper 报告（仅仅是因为这不是 JSF 视图......）。但那是另一回事了。顺便说一句，您不会以任何方式将报告写入响应正文。也许那是你真正的问题？
