Subject AW: Using Datagrid together with Servlet Version 2.4
Date Tue, 10 May 2005 13:52:24 GMT
Hi Néstor,

Thank you very much for your quick response. 
The datagrid-taglib is really great. I'm going to use it as soon as it is available.

Regards,

Christian

Hi Christian

The problem is that the datagrid does not work with servlet version 2.4. We are currently
planning to develop a 2.4 version. If I have something I'll let you know.

Regards,

Néstor Boscán

Asunto: Using Datagrid together with Servlet Version 2.4

Hi all,

I have got a big problem using the datagrid taglib and I hope someone can help me. 

When I am trying to use the datagrid taglib together with the following header of my web.xml
file, an error occurs.


<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app 	xmlns="http://java.sun.com/xml/ns/j2ee" 
	
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
			version="2.4" 
	
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   
	
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
.
.
.

The error is: "According to TLD or attribute directive in tag file, attribute items does not
accept any expressions"

The Code of my jsp-file is (taken from the datagrid-examples):

<ui:dataGrid items="${employees}" var="employee" name="datagrid1"
cellPadding="1" cellSpacing="0">
  <columns>
    <column width="100" order="true">
      <header value="Name" hAlign="center" styleClass="header1"/>
      <item   value="${employee.firstName} ${employee.lastName}"
hAlign="left" styleClass="item1"/>
      <aggregate function="count" var="total"/>
      <footer value="Total ${total}" hAlign="left"
styleClass="footer1"/>
    </column>
.
.
.

If the header of my web.xml file is replaced with the following lines, everything works fine
(taken from the datagrid-examples).

<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems,
Inc.//DTD Web Application 2.2//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>

Because I am using Struts and some other things in my web-project, I need version 2.4.
And because I am a newbie in this area, I don't know, how to solve this problem. Thank you
in advance for your help.



Best Regards

Christian
