在jsf中通过FacesContext访问上下文；
Hssf通过 HSSFWorkbook 向输出流写入；
具体代码：

Bean：

public class TestBean {
    public String action() {
        HSSFWorkbook wb = new HSSFWorkbook();
        FacesContext context=FacesContext.getCurrentInstance();
        HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
        response.reset();
        response.setContentType("application/ms-excel");
        try {
            response.setHeader("Content-disposition", "attachment;filename="+new String("下载Excel.xls".getBytes(),"iso-8859-1"));
            wb.write(response.getOutputStream());
        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        FacesContext.getCurrentInstance().responseComplete();
        return null;
    }
}

以上只是一个空的简单的Excel 具体怎么创建符合项目要求的参看：HSSF GUIDE！
faces-config.xml:

<managed-bean>
        <managed-bean-name>testmanaged-bean-name>
        <managed-bean-class>yds.study.web.TestBeanmanaged-bean-class>
        <managed-bean-scope>sessionmanaged-bean-scope>
    managed-bean>

jsp：

<f:view>
    <h:form>
        <h:commandButton id="button" value="下载" rendered="true"
            action="#{test123.action}" />
    h:form>
f:view>

ok这样就可以了;)
