難道能這樣做。在一個頁面指向添加h:commandLink到你的bean的操作方法：

<h:commandLink value="download report" action="#{myBean.downloadReport}" /> 

在你豆你應該生成報表，並將其寫入到響應的OutputStream：

public class MyBean { 

    public String downloadReport() { 

    // get HttpServletResponse 
    FacesContext context = FacesContext.getCurrentInstance(); 
    HttpServletResponse response = 
     (HttpServletResponse) context.getExternalContext().getResponse(); 

    // set correct content type 
    response.setContentType("application/pdf"); 

    // get OutputStream 
    OutputStream stream = response.getOutputStream(); 

    // TODO: generate PDF and write the report to this output stream 

    // mark response as completed 
    context.responseComplete(); 
    return null; 

    } 
}
