Gurpreet,
I have faced same problem and got the solution too. Actually I have taken
struts-config.xml file from my old project and DOCTYPE in
struts-config.xml was having old URL of apache given as bold in following
doctype.
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd";>
While i was having newer version of jar file in which
struts-config_1_2.dtd was having following DOCTYPE and URL of apache was
newer one given as bold in follwoing doctype.
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://struts.apache.org/dtds/struts-config_1_2.dtd";>
Now if your computer is on internet then it will connect to
http://jakarta.apache.org as well as http://struts.apache.org. On
standalone computer it will try to resolve from DTD file in JAR file
itself but due to mismatch it will not be able to resolve and then it will
try to connect to internet and end result is "UnknownHostException"
exception.
Moral of he story is check DOCTYPE in your xml file and match it with
corresponding DTD in struts.jar file.
Hope it helps..

RE: Developing and running Struts on Tomcat without an Internet Connection
You are referring to the tab lib files which are hosted on
jakarta.apache.org website.
When you are connected to the internet it get resolved by your web
server and the moment you unhook it
The problem starts. Best practice is to download the same tab lib files
(Tld) and copy them in any of the folder under
Your web application> once done change the path in your JSPs to load the
tld file from your local path instead of jakarta.apache.org
