Re: JSTL and EL question - SOLVED

[Jeff Knox]

I thought I liked the idea of having the taglib in the web.xml file. 
When I try it I'm getting "This absolute uri 
(http://java.sun.com/jstl/core) cannot be resolved in either web.xml or 
the jar files deployed with this application". Do I have to download it 
somewhere in order to use it in the web.xml file? Any ideas?

Thanks,

Jeff

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"; %>

can you also send the taglib line from the top of jsp?

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.
