Can not display data from DB

Hello everyone,

 

I am trying to figure out why I can not retrive and

display my data with my jsp from the servlet. I access

data from the servlet then pass it on to a jsp to display it.

 

at first I thought it was due to the fact that the servlet was

not added to my web.xml descriptor, so I did.

 

I am using displaytag to present data, I get this error in the jsp

 

Unable to load tag headler class “org.displaytag.tag.el.ELTableTag” for display: Table.
 

It is pointing to this in my jsp:

 

 <display:table name="sessionScope.baleent" uid="datum" defaultsort="1" defaultorder="descending" pagesize="7" class="tabledata">

 

But in my jsp I have a header as:

 

<%_at_taglib uri="/WEB-INF/displaytag-el.tld" prefix="display"%>

 

and I have added this in my web.xml descriptor:

 

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

            <taglib-location>/WEB-INF/displaytag-el.tld</taglib-location>
        </taglib>
    </jsp-config>
    </web-app>


 

 

 

I get the following error from the server log:
