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:
 
<%@... 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">

        <servlet-name>Controllerserv</servlet-name>
        <servlet-class>servlet.Controllerserv</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Controllerserv</servlet-name>
        <url-pattern>/Controllerserv</url-pattern>
    </servlet-mapping>

        <session-timeout>

    </session-config>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    <jsp-config>
        <taglib>
            <taglib-uri>http://displaytag.sf.net</taglib-uri>
            <taglib-location>/WEB-INF/displaytag-el.tld</taglib-location>
        </taglib>
    </jsp-config>
    </web-app>

 
 
 
I get the following error from the server log:

Thank you.
 
The bean was there, I just forgot to implement the persistence API within my bean:
 
@PersistenceContext
 
Thank you.
