jsp - Accessing c:var variable inside sql:param -

i facing problem in accessing jsp "core tag" in jsp "sql tag" query.

code :

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>  <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>   <sql:setdatasource     var="myds"     driver="org.postgresql.driver"     url="jdbc:postgresql://localhost:xxxx/xyz"     user="xyz" password="test123" /> <% string user_email = session.getattribute("email").tostring();     out.println("email = "+ user_email); %>   <c:set var="emailid" value= "${user_email}"/>  <sql:query var="listusers"   datasource="${myds}">      select * developer_apikey_registration email_id = ?  ;     <sql:param value="${emailid}"/>   </sql:query> 

i not able email value here. although checked coming correctly in session attribute.

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>  <sql:setdatasource     var="myds"     driver="org.postgresql.driver"     url="jdbc:postgresql://localhost:xxxx/xyz"     user="xyz" password="test123" />   <c:set var="emailid" value= "${sessionscope[user_email]}"/> <sql:query var="listusers"   datasource="${myds}">     select * developer_apikey_registration email_id = ?  ;     <sql:param value="${emailid}"/> </sql:query>
