public ActionForward unspecified(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		QueryPost query=new QueryPost();
		UserDaoiBatis ibatis=new UserDaoiBatis();
		PrintWriter printWriter = response.getWriter(); 
	List list=ibatis.selectUser();
		InputStream reportStream =getServlet().getServletConfig()
		.getServletContext().getResourceAsStream("/reports/DbReport.jasper");
		JasperPrint	jasperPrint = JasperFillManager.fillReport(reportStream,   
                new HashMap(), new JRBeanCollectionDataSource(list));  
	
        JRHtmlExporter htmlExporter = new JRHtmlExporter();   
        response.setContentType("text/html");   
        request.getSession().setAttribute(   
                ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,   
                jasperPrint);   
           
        htmlExporter.setParameter(JRExporterParameter.JASPER_PRINT,   
                jasperPrint);   
        htmlExporter.setParameter(JRExporterParameter.OUTPUT_WRITER,   
                           printWriter);   
        htmlExporter.setParameter(JRHtmlExporterParameter.CHARACTER_ENCODING, "gb2312");   
        htmlExporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,   
                "image?image=");   
        htmlExporter.exportReport();   
    
        System.out.println("done!");   
  

		return null;

	}

下面是错误发生的地方java.lang.IllegalArgumentException: No SqlMapClient specified
	org.springframework.util.Assert.notNull(Assert.java:112)
	org.springframework.orm.ibatis.SqlMapClientTemplate.execute(SqlMapClientTemplate.java:164)

问题补充：
	//查询所有用户

	public List selectUser() {

		return getSqlMapClientTemplate().queryForList("selectUsers");

		

	}
