Running MyEclipse 8.6M1-20100525 on OSX.

Created a simple Web Project application on J2EE 5.0 (there was a grayed option displays to add JSTL support when I created the project).

The top of the page contains:

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>

I have a sql:setDataSource tag that doesn’t display any warnings, and added:

<sql:query var="queryResult" dataSource="${dataSrc}">
...my sql query here
</sql:query>

On the sql:query tag, I have the little yellow warning sign, and the message is “Invalid attribute (dataSource)”.

I also have in the page body:

<c:forEach var="row" items="${queryResult.rows}" >
    <c:out value="${row.user_display_nm}" /> <br />
</c:forEach>

And the little yellow triangle says “Invalid attribute (items)”.

Right-clicking on the project root displays a grayed-out “Add JSTL Libraries”

Expanding the Java EE 5 Libraries for the project includes jstl-1.2.jar.

Running the project fails with:

org.apache.jasper.JasperException: /tips.jsp(76,0) According to TLD or attribute directive in tag file, attribute dataSource does not accept any expressions

    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

I haven’t used JSTL in a very long time, but this should be easy. Is there something I’m missing?

Thanks.

CasaDelNorte,
Since you are using J2EE5, jstl1.2, can you change your taglib directive to include /jsp as shown below

<%@ taglib prefix=”c” uri=”http://java.sun.com/jsp/jstl/core&#8221; %>
<%@ taglib prefix=”sql” uri=”http://java.sun.com/jsp/jstl/sql&#8221; %

Please refer to the following link for further reference –

2. http://www.mularien.com/blog/2008/04/24/how-to-reference-and-use-jstl-in-your-web-application/
Let me know if that helps.
