严重: Servlet.service() for servlet action threw exception
org.apache.jasper.JasperException: /pages/zhbg/sfw/lwdj/TOaLwdjjbxxEdit.jsp(272,5) "${empty dbean.lwdl ? param.fmdid:dbean.lwdl}" contains invalid expression(s): javax.el.ELException: Error Parsing: ${empty dbean.lwdl ? param.fmdid:dbean.lwdl}

原因是：Tomcate 6.0不支持，Tomcate 6.0.18支持
