So what does that exception tell you?
(I have very limited internet access today, so I can't look up the
requirements for displaytag. but do you have all the required libraries for
it?)

Seems you missed to add the Apache Commons Lang library jar file.
I have projects running with displaytag 1.1.1 and commons-lang 2.3.
(Don't know if the last 2.4 version work though.)

arum,
Read this *entire* page paying particular attention to point 2
"dependencies":
http://displaytag.sourceforge.net/11/install.html
A ClassNotFoundException always implies you're missing a jar in the
classpath.

The exception is telling you precisely what class is missing; this is a clue
as to what may be wrong.
Do you have *all* the libraries you need for using displaytag?
You can't just randomly add libraries to your application and expect it to
work: libraries have their own sets of dependencies. You almost certainly
don't have all the dependencies that displaytag requires.
Look up the dependencies for displaytag and make sure you have them all.
Here's the link:
http://displaytag.sourceforge.net/11/displaytag/dependencies.html
This is Java 101. I'd consider taking some time to learn the environment
within which you're attempting to program; it will almost certainly save time
and aggravation.

Please note:
java.lang.NoClassDefFoundError: *org/apache/commons/lang/UnhandledException
*
Indicates the classloader couldn't find a class (which one, you may ask?).
Looks like commons.lang couldn't find the UnhandledException class. Please
make sure you have all displaytag dependencies. You may want to consider
using maven2 to avoid these problems.

yes i have already put the display tag jr file in my lib folder
only problem in my opinion is use of
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>
tag lib directiveas removing this directive will aslo remove the exception,
according to exceptin it is unable to find the class.
myself also trying to use the display tag first time with struts2 and i am
also not sure abot how to configure it with struts2.
