how to deploy GWT app to tomcat

I searched this site for answer to this question and couldn't find a solution. what i did is that i simply compress the war directory in my eclipse GWT app project then rename it to .war then drop it to tomcat webapps folder. when i run the web app, the first screen is successfully shown but when i call a servlet within my src code it gives me resource not found by tomcat server. i'm sure i have added entry for servlet in web.xml file and the app worked well when i run it in eclipse gwt dev mode. something prevent my servlets (standard servlets not GWT RPC servlets) to be found and executed by tomcat. what could be the reason?

UPDATE

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!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>

  <!-- Servlets -->

  <servlet>
        <servlet-name>OAuth</servlet-name>
        <servlet-class>org.goauth.server.OAuthServlet</servlet-class>

    </servlet>
    <servlet-mapping>
        <servlet-name>OAuth</servlet-name>
        <url-pattern>/goauth/oauth</url-pattern>
    </servlet-mapping>
     <servlet>
        <servlet-name>OAuthCallback</servlet-name>

        <servlet-class>org.goauth.server.OAuthCallbackServlet</servlet-class>

    </servlet>
    <servlet-mapping>
        <servlet-name>OAuthCallback</servlet-name>
        <url-pattern>/goauth/callback</url-pattern>
    </servlet-mapping>
    <servlet>
        <servlet-name>service</servlet-name>

        <servlet-class>org.goauth.server.OAuthServiceImpl</servlet-class>

    </servlet>
    <servlet-mapping>
        <servlet-name>service</servlet-name>
        <url-pattern>/goauth/service</url-pattern>
    </servlet-mapping>
    <servlet>
        <servlet-name>OAuthConfirm</servlet-name>
        <servlet-class>org.goauth.server.OAuthConfirmServlet</servlet-class>

    </servlet>
    <servlet-mapping>
        <servlet-name>OAuthConfirm</servlet-name>
        <url-pattern>/goauth/confirm</url-pattern>
    </servlet-mapping>
  <!-- Default page to serve -->
  <welcome-file-list>
    <welcome-file>GOAuth.html</welcome-file>
  </welcome-file-list>    
</web-app>

I found the problem : for invoking my servlet i was calling a url of the format : "/goauth/OAuth" this worked with eclipse gwt plugin in dev mode but not when i deploy war to tomcat server. the solution is that my url pointing to my servlet should be of the form :

String href = GWT.getHostPageBaseURL()+"goauth/OAuth";

so we need to tell tomcat the full url by prefixing servlet url with GWT.getHostPageBaseURL().

In your mapping, try changing /goauth/oauth to /OAuth
