jsp pages sql error using tomcat and eclipse error = : The index 1 is out of range

I am having a problem with my jsp page. I am using:-

-Tomcat 8.0.20

-Eclipse Java EE luna SR2

-Microsoft SQL server 2005

-Using management studio express to do my db work

It's a small problem as i am learning to run queries on jsp pages. I have stumbled upon this problem and wondered if anyone can help me.

this is my code snippet

 <sql:setDataSource var="snapshot" river="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
 url="jdbc:http://sqlserverSANGKARAN;database=ILMU;" 
 user="*******" password="******"/>

<c:set var="empId" value="102"/>

<sql:update dataSource="${snapshot}" var="count">
 UPDATE Employees SET last VALUES = 'Ali'
 <sql:param value="${empId}" />
</sql:update>

This is the error

org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException:

UPDATE Employees SET last VALUES = 'Ali'

The index 1 is out of range. org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:548) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:454) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:396) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:340) javax.servlet.http.HttpServlet.service(HttpServlet.java:725) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)
