Hi,
I am trying to use JSTL in my
JSP.
My class is like this:
package myclasses;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class MyJstl extends HttpServlet{
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException{
String[] music = {"1","2","3","4","5"};
req.setAttribute("music",music);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/MyJstlJsp.jsp");
rd.forward(req,res);
}
}
And Jsp is
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html><body>
<c:forEach var=arr items=${music} scope="session">
<tr>
<td>
${arr}
</td>
</tr>
</c:forEach>
</body></html>
And DD is like this:
<
servlet>
<servlet-name>MyJstl</servlet-name>
<servlet-class>myclasses.MyJstl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyJstl</servlet-name>
<url-pattern>/MyJstl.do</url-pattern>
</servlet-mapping>
But when i Try to call the Servlet with servletcontext/MyJstl.do
I get the error:
org.apache.jasper.JasperException: The absolute uri:
http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
