java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/sql/SQLExecutionTag - sql

Question

I'm getting an error when I'm trying to run a JSP file with some JSTL tags specially SQL in it... in Tomcat server.
I can make out.. it clearly says, some problems with SQL but here what i have in my code.;
<%# page language="java" contentType="text/html; charset=ISO-8859-1"%>
<%# taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<sql:setDataSource dataSource="EMS_DataSource" />
<sql:query var="qryGet" >
SELECT ems_emp_id, ems_emp_fname, ems_emp_lname FROM riz_ems_emp
</sql:query>
<c:forEach var="row" items="${qryGet.rows}">
<tr>
<td><c:out value="${row.ems_emp_id}" /></td>
<td><c:out value="${row.ems_emp_fname}" /></td>
<td><c:out value="${row.ems_emp_lname}" /></td>
</tr>
</c:forEach>
Apart from this, I have correctly closed all my relevant tags.
Someone Please tell me the reason for this error.
NOW: I changed my jars to jsp-api-2.0.jar and jstl-1.2.jar.
now the error i get is ;
Unable to compile class for JSP: The method getELContext() is
undefined for the type PageContext

Answer 1

You are overriding the values for the default database configuration . You should provide your datasource in the <sql:query> tag as,
<sql:setDataSource var=dbDetails dataSource="EMS_DataSource" />
<sql:query dataSource=${dbDetails } var="qryGet" >
SELECT ems_emp_id, ems_emp_fname, ems_emp_lname FROM riz_ems_emp
</sql:query>
Also make sure you have specified the enough attributes for the sql:setDataSource tag.
Hope this helps !!
