JSTL sql tag error: No suitable driver

[Mike Cantrell]

I'm trying to use the sql JSTL tags on JRun 4.0 and I'm not having any 
luck with their pooled dataSources. I get the following error:

     javax.servlet.jsp.JspException: Unable to get connection, 
DataSource invalid: "No suitable driver"

Here's how I'm using the tag:

    <%@ taglib uri="/WEB-INF/tlds/sql.tld" prefix="sql" %>
    <%@ taglib uri="/WEB-INF/tlds/c.tld" prefix="c" %>   
        <sql:query dataSource="dev" var="test">
            select * from dn_user
        </sql:query>
        <c:forEach var="row" items="${test.rows}">
            <c:out value="${row.login}" />
        </c:forEach>

I also tried calling it with dataSource="java:comp/env/jdbc/dev" as 
well. I thought it must be JRun so I tried grabbing the DataSource 
manually and I had no problems:

    InitialContext ctx = new InitialContext();
    DataSource ds = (DataSource) ctx.lookup("dev"); // works with 
java:comp/env/jdbc/dev also
    Connection dbConnection = ds.getConnection();

I also tried the dbtaglibs which worked fine as well:

    <%@ taglib uri="/WEB-INF/tlds/dbtags.tld" prefix="sql" %>
      <sql:connection id="conn1" jndiName="dev"/>
            <sql:statement id="stmt1" conn="conn1">
                <sql:query>
                 select * from dn_user
                </sql:query>
                <sql:resultSet id="rset2">
                    <sql:getColumn position="1"/><br>
                </sql:resultSet>
           </sql:statement>
        <sql:closeConnection conn="conn1"/>

I have no idea what's wrong. I must be missing something but I'm not 
sure what it is.  Ugh, I need help :)
