Problem using swing with struts

[sugantha]

Hello all.. I am developing an application where I use struts 2 and an
applet based client side...

>From the applet, I create an ObjectOutputStream to write the parameters to
the struts action.. and for invoking the struts action, I create an
ObjectInputStream by specifying the URL in the following way..

*
   servletURL = new URL("
http://172.24.30.15:8084/Chapter1/displayCustDetails";);
   servletConnection = (HttpURLConnection) servletURL.openConnection();
   returnFromServlet = new ObjectInputStream(servletConnection
                       .getInputStream());  *


My web.xml file is as follows...

  *<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>
*

My struts.xml is as follows...
*
  <struts>
      <package name="default" extends="struts-default">
          <action name="displayCustDetails"
class="com.common.web2.UserDetailsAction">
           </action>
       </package>
  </struts>
*
Now, whenever I try to invoke my code, it gives the below error message..

java.io.FileNotFoundException:
http://172.24.30.15:8084/Chapter1/displayCustDetails



I have the same application, where struts 1.1 is used in combination with
swing. Problem comes when I try to migrate this to struts 2. Any suggestions
are appreciated. Thanks in advance.
