Error:"Servlet action is currently unavailable"

Question

Hi,
I wrote a servlet program, when I run in URL
"http://localhost:8080/Tomcat1/" its working fine.
But
"http://localhost:8080/Tomcat1/first.do" its throwing an error
message Servlet action is currently unavailable
description The requested service (Servlet action is currently unavailable) is not currently available.
Please tell me the reason.
Thanks,
Hari

Hi,
I checked & tried, no progress.
I'm attaching web.xml & struts-config.xml.
Please let me know the issues.
web.xml
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"

<!--
This is a blank Struts configuration file with an example
welcome action/page and other commented sample elements.
Tiles and the Struts Validator are configured using the factory defaults
and are ready-to-use.
NOTE: If you have a generator tool to create the corresponding Java classes
for you, you could include the details in the "form-bean" declarations.
Otherwise, you would only define the "form-bean" element itself, with the
corresponding "name" and "type" attributes, as shown here.

This plugin initialize Tiles definition factory. This later can takes some

     are optional.
The plugin should be declared in each struts-config file.
- definitions-config: (optional)
Specify configuration file names. There can be several comma
          separated file names (default: ?? )
- moduleAware: (optional - struts1.1)
Specify if the Tiles definition factory is module aware. If true
(default), there will be one factory for each Struts module.
               If false, there will be one common factory for all module. In this
later case, it is still needed to declare one plugin per module.
The factory will be initialized with parameters found in the first
initialized plugin (generally the one associated with the default
module).
               true : One factory per module. (default)
               false : one single shared factory for all modules
     - definitions-parser-validate: (optional)
     Specify if xml parser should validate the Tiles configuration file.
               true : validate. DTD should be specified in file header (default)
               false : no validation
     Paths found in Tiles definitions are relative to the main context.
