Recently I have upgraded from Struts 1.1 to Struts 1.3.8. I get the

My Server starts successfully without any Struts issues if I've internet
access.
I checked for all the DTDs/XSDs & TLD files which have 'java.sun.com' as
part of the URI.
Currently I have the following TLD/DTD files presentunder \resin-
pro-3.1.3\webapps\<my-app>\WEB-INF\tld

You shouldn't need any TLD or DTD files in your WEB-INF folder.
Regardless, though, the issue is with one of your XML files referencing
a DOCTYPE that's not resolved, so it's your XML files you want to pay
attention to.
I would like to know, which DTD/TLD/XSD file is causing ActionServlet-init
to throw the following error. Recently while I read at
http://struts.apache.org/1.x/userGuide/installation-was352
-x.html<http://struts.apache.org/1.x/userGuide/installation-was352-x.html>
WAS != Resin, so I don't know how relevant that document would be to
your case.
For whatever reason, some installations do not like XML files that reference
PUBLIC DTD's - if in looking at the default_host_stdout.log file you see
errors about invalid public URL references during DTD registrations, or if
your pages say "cannot find //logon or //saveRegistration (ie. action
mappings) then do the following:
1. Stop Default Server
2. Go to servlets\WEB-INF\ and edit web.xml and struts_config.xml.
3. In the DOCTYPE declaration, change the word PUBLIC to SYSTEM and
completely remove the line that reads "-//Sun Microsystems, Inc.//DTD Web
Application 2.2//EN" from web.xml and remove "-//Apache Software
Foundation//DTD Struts Configuration 1.0//EN" from struts-config.xml.
Did you try that? Did it make a difference?
What I would suggest is to look at each XML file you have (web.xml,
struts-config.xml, etc.) and look at the values for the SYSTEM and
PUBLIC identifiers in the DOCTYPE declaration at the top. Most likely,
you have one of those specified incorrectly.
If you can't spot which one is wrong, try building a minimal WAR with
only a web.xml and no other config files, then gradually gradually add
stuff back in until you discover which config file is causing the problem.

Appreciate your help in getting rid of this exception.
