Unable to Deploy WAR file (Unknown assembly root-tag attribute: version)

Question

Hello,
I created a simple web application with eclipse + tomcat plugin + struts2 (JPA Spring Hibernate ) and created the WAR file using the tomcat plugin compiler. When I deploy the war file into Tomcat 6 the file is deployed properly and i can view the website properly. But when I try to deploy the the WAR file from Oracle 9i Application Server I get the following error.
Failed to deploy web application "mytest". Nested exception Root Cause: Error loading web-app 'mytest' at C:\ora9ias\j2ee\MySystem\applications\mytest\mytest: Unknown assembly root-tag attribute: version; nested exception is: java.lang.InstantiationException: Error loading web-app 'SFPD' at C:\ora9ias\j2ee\MySystem\applications\mytest\mytest: Unknown assembly root-tag attribute: version.
My Current web.xml is this.
<?xml version="1.0" ?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Thanks for the reply sasesha,
I've changed my web.xml to
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
     "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>     
     <display-name>My Test Project System</display-name>
     <filter>
          <filter-name>struts2</filter-name>
          <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
     </filter>
     <filter-mapping>
          <filter-name>struts2</filter-name>
          <url-pattern>/*</url-pattern>
     </filter-mapping>
     <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>
     <welcome-file-list>
          <welcome-file>index.html</welcome-file>
     </welcome-file-list>
</web-app>
During the initial upload the previous error doesn't show anymore, however, I'm getting this new error and currently I'm a bit at a loss since i included the spring.jar library file in my war file. I tried the new war file in Tomcat and the war file deploys fine. Am I missing a configuration or setup ?
