When I'm using display tag "<display:table name="${users.rows}" id="user"
class="list">"
result is empty table (Nothing found to display.).

With following code everything looks fine.
"<display:table name="pageScope.expanses.rows" id="rows" class="list">"

I still can't get rows from table using "value="<c:out
value="${user.firstName}"/>" ".
How I can retrieve "users" using ${user.username} expression.

CODE EXAMPLE
************************************************************ ******
<sql:query var="users" >
select id, username, firstName, lastName
from temp_user order by upper(username)
</sql:query>

<display:table name="${users.rows}" id="user" class="list">
<display:column title="Username">
<input type="text" name="username" style="padding: 0"
value="<c:out value="${user.username}"/>" />
</display:column>
</display:table>

************************************************************ ******

Result for "value="<c:out value="${user.username}" is "${user.username}".

Probably I forget to set something on my JSP page or in web.xml file.
I have spend few day to find solution.
Hope that somebody can help me.

Thanks!
Branko

First things first...the 'display', 'sql' and 'c' taglibs you are using:
are they Expression Language versions? In other words, does this work
as you would expect?

value="<%=user.getUsername();%>"

If it does, that would suggest that your c.tld taglib *isn't* an EL
version. Ditto for your 'display' taglib.

How I can recognize c.tld taglib EL version?

Thanks

(whoops...that semi-colon shouldn't be there)

I use the Apache taglibs. The c.tld descriptor is the EL version,
c-rt.tld is not. And inside the c.tld file the 'out' tag's Java class
is 'org.apache.taglibs.standard.tag.el.core.OutTag', whereas the
c-rt.tld tag is 'org.apache.taglibs.standard.tag.rt.core.OutTag'.

Are you importing the TLD properly in your JSP?

Something like this in your JSP:

<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>

I am using EL version properly.
I doesn't have "listener" in my application.
Maybe problem is there.

I saw in web.xml something like this.

<listener>

<listener-class>org.apache.taglibs.standard.examples.startup.Init </listener-
class>
</listener>

Examples I have work fine with ${user.username} expression when they have
above deployment descriptor and class.

Problem can be in <sql:query>. It retrieve table not object.
