Re: Servlet -: Error running from WAR file

Did you add the servlet and servlet mapping entries to your web.xml? Example:

JSP Syntax (Toggle Plain Text)

<servlet>
  <servlet-name>myServlet</servlet-name>
  <servlet-class>servlet.myServlet</servlet-class>
  <init-param>
    <param-name>load-on-startup</param-name>
    <param-value>0</param-value>
  </init-param>
</servlet>
 
<servlet-mapping>
  <servlet-name>myServlet</servlet-name>
  <url-pattern>/myServlet</url-pattern>
</servlet-mapping>
