[Eclipse] How to use local DTDs to validate XMLs

I have multiple Eclipse versions installed in my Ubuntu 12.04, so I wanted to have separate launcher icons in Launchpad. However I noticed it is not possible to create launch icons simply using:
"Right click -> Lock to Launcher" approach since the same launcher icon is used for all Eclipse installations; simply said there will be only one launcher icon for all Eclipse installations. 


It is quite easy to create multiple launcher icons for multiple installations. Below is the 4 steps you need to follow.
