ping CDC device in to Machine(our desktop or notebook)

step 1: config the device into system and vice versa
this configuration in linux machine
1. ifconfig usb0 ip1 netmask maskid (this at linux machine) - machine -1
eg:- ifconfig 10.100.100.101 usb0 netmask 255.255.255.0
2. ifconfig usb0 ip2 netmask maskid (this is at device machine) - machine 2
eg:- ifconfig 10.100.100.102 usb0 netmask 255.255.255.0

Struts Tutorial Page

           Difference between Model 1 and Model 2 architecture: Features of MVC1: Html or jsp files are used to code the presentation. To retrieve the data JavaBean can be used. In mvc1 archictecture all the view, control elements are implemented using Servlets or Jsp. In MVC1 there is tight coupling between page and model as data access is usually done using Custom tag or through java bean call. Features of MVC2: The MVC2  architecture removes the page centric property of MVC1 architecture by separating Presentation, control logic and the application state. In MVC2 architecture there is only one controller which receives all the request for the application and is responsible for taking appropriate action in response to each request. Struts framework provides three key components: A  request  handler provided by the application developer that is used to  mapped to a particular URI. A  response  handler which is used to...
