Wi-Fi network are not secure

Wi-Fi may not in itself be insecure, but various implementations of the wireless technology are. The most vulnerable of these are "open" networks, which don't even require a password or network key to use. Unfortunately, open networks are common; indeed, most of the free networks you encounter in coffee shops, hotel lobbies, and other public spaces fall into this category. Whenever you use an open network, the information you send and receive is exposed for all to see. And there are plenty of nasty types lurking around who want to see it. They are looking for confidential information in your e-mails, SMS messages, and other Web communications that would enable them to steal your passwords, personal identity, and money. Stealing information from traffic on an open Wi-Fi network is relatively easy. You don't have to be a technical expert or hacker because there is a wide range of tools available for download that allow just about anyone to tune into and record other people's communications. One such program is the free Wireshark utility, which Ryan Russell described in his Mar. 20 Perimeter Scan column. Hey, there's even a YouTube video showing how to do it. So the next time you're considering using an open network, remember that the person at the next table or in the next room may be listening in. If that thought makes you uncomfortable, here are some things you can do to prevent being a wireless victim. Read full article by Ian "Gizmo" Richards

Change struts2 .action suffix

Just found this works when you want to change the suffix for struts2 framework from dot action(.action) to some other suffix like for eg: dot htm (.htm)

1. You will have web.xml as below:

  struts2
  org.apache.struts2.dispatcher.FilterDispatcher 



  struts2
  /*

2. Add below line of code to override "struts.action.extension" value in struts.xml

OR

Create struts.properties file and place along with struts.xml or in other folder but don't forget to set a classpath for it if you put this file into other folder, the code in properties file will be as below:

struts.action.extension=htm

Note: This action just override the extension value which use by DefaultActionMapper in struts2 as ".action" when we extend "struts-default" interceptor.
Refer here for more struts2 constant configuration.

Unable to install Live Messenger in Windows XP box

The application failed to initialize properly (0xc0150004). Click OK to terminate the application This error frustrated me when I try to install Windows Live Messenger version 2009 in my XP box. After googling for sometime, those information doesn't help much, as I try to uninstall windows messenger, install dot net framework etc. When the time i suspect it might be affected by virus or due to hardware problem, I try to update my Windows XP services pack from default services pack 2 to services pack 3, guess what..... Hurray !!! it works now :) p/s: Try to update your services pack when you face above problem during install Live Messenger
