JSP or EL expression is not evaluated. I have seen couple of times JSP directly displaying the el-expression on webpages.
It may be because of couple reasons
1) Typo in your jsp.
2) Attributes are not set in reqeust or pageContext.
3) You have not enabled EL expression in your JSP or not enabled in your web container.
From Servlet specs 2.5 finally El expression are enabled by default. You don’t need enabled them manually in your JSP.
In case you are using older version Servlet Container, add following line to enable them.
<%@ page isELIgnored="false" %>
