My code is
In Servlet i am getting list of my table data and place it in a session the list is getting correctly

                List<Student> allList = stdentDb.showAll(); //for passing list of all java bean parameters to jsp
                session.setAttribute("student", allList);

Jsp page:

<display:table name="sessionScope.student" export="true" uid="std" sort="list">
      <display:column title="Name " sortable="true">
        <c:out value="std.STD_FIRSTNAME"/>
        <c:out value="std.STD_MIDDLENAME"/>
        <c:out value="std.STD_LASTNAME"/>
      </display:column>
    </display:table>

I have added commons-beanutils1.82.jar,Displaytag-1.2.jar,log4j-1.29.jar to my project path and i placed them in lib folder under WEB_INF folder.
FYI: I am using JDEVELOPER 11, Oracle Database

Are all those files present inside the WEB-INF/lib inside the app in the server? It's not WEB_INF...

Sorry my mistake, the jar files are in WEB-INF/lib folder only. But it is still showing same error
