struts2 project is not deploying properly in tomcat7

Question

My project runs perfectly in eclipse. But when I export its war file to the tomcat7 on my linux server, it is not unpacking the war file. Even after I do it manually, it says the requested resource is not available

The other war file also had the same problem.But when unpack it manually it worked.

I'm not sure what the problem is.

My Web.xml is

 <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>  
  <filter>
  <filter-name>struts2</filter-name>
  <filter-class>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
  </filter>
  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
   <session-config>
         <session-timeout>-1</session-timeout>
 </session-config>
</web-app>

And my struts.xml is

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration
2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

        </action>
        <action name="Finance_Report" class="EffortAction">
            <result name="success">Report.jsp</result>
        </action>
        <action name="Pivot" class="Downloads">
            <result name="success" type="stream">

                <param name="bufferSize">1024</param>
            </result>
        </action>       
    </package>
</struts> 

The library files that I use are

commons-fileupload-1.3.1.jar
commons-io-2.2.jar

I have checked similar question under stackoverflow, but I am unable to figure out what goes wrong in my case.

Answer 1

I have found a workaround.

I have deleted the war file and the folder that I created manually, and then restarted the server. Now I deployed the war once again, and it worked. But I am not sure what was the reason that blocking me previously.

Hope this helps someone.
