Re: JSTL and EL question - SOLVED

[Jeff Knox]

I never thought about putting the tablib in the web.xml file. I like 
that! As for referencing the tablibs on individual pages there are four 
differentlibraries you can use depending on what you need to do on the 
page. The core library is:

   <[EMAIL PROTECTED] prefix="c" uri="http://java.sun.com/jstl/core"; %>

For internationalization and formatting:

    <[EMAIL PROTECTED] prefix="fmt" uri="http://java.sun.com/jstl/fmt"; %>

Database access:

   <[EMAIL PROTECTED] prefix="sql" uri="http://java.sun.com/jstl/sql"; %>

XML parsing and transforming:

   <[EMAIL PROTECTED] prefix="x" uri="http://java.sun.com/jstl/xml"; %>

I'm still having problems. Can you please post a complete sample along
with
web.xml sample?
What exactly are your problems?

In web.xml you should declare taglibs:

 <taglib>
  <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
  <taglib-location>/WEB-INF/c.tld</taglib-location>
 </taglib>
 <taglib>
  <taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>
  <taglib-location>/WEB-INF/sql.tld</taglib-location>
 </taglib>
 <resource-ref>
  <res-ref-name>jdbc/EVracunDS</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>
 </resource-ref>
And then use this in your JSP:

<sql:setDataSource dataSource="EVracunDS"/>
<sql:query var="userData">
  SELECT * FROM user_tab WHERE user_id = ?
  <sql:param value="${userID}"/>
</sql:query>
...
<c:set var="userRow" value="${userData.rows[0]}"/>
<c:out value="${userRow.user_id}"/>
...
Nix.
