Hi Sean,
Thanks for your reply. I use Clojure.Jar version 1.2.0 and the
contrib.jar is also the same version.
Copied below is the stack trace of the Error:

************ Copied below is the code snippet of agent.clj which has the
import statement. *******************
(ns nlplabs.webfetch.agent
(:refer-clojure)
(:use nlplabs.lib nlplabs.webfetch.scheduler nlplabs.webfetch.util
clojure.contrib.str-utils)
(:import (com.gargoylesoftware.htmlunit BrowserVersion
Page
JavaScriptPage
UnexpectedPage
TextPage
WebClient
MockWebConnection
History)
......
))
The error comes when it tries to load WebClient Class. WebClient.java
imports BaseFrameElement Class. When I comment WebClient, the compilation
passes through.
Let me know if you need any more information.
Regards
Vasu
