You can add snow storm for your web site easily.....
Copy the following code to a new javascript file....
var snowStorm = null;

this.flakesMaxActive = 64; // Limit amount of snow falling at once (less = lower CPU use)

this.targetElement = null; // element which snow will be appended to (document body if null/undefined) - can be an element ID string, or a DOM node reference
this.followMouse = true; // Snow will change movement with the user's mouse

// --- less-used bits ---

Assume that we saved this code in a javascript file called snow.js....
Then import that file on your master page.
<script type="text/javascript" src="snow.js"></script>
Then click the install button below and continue with installing...
Select Tomcat 6.0 (according to your sever version) and continue. 
You can simply start server by right click on tomcat and selecting start option.
Add a desired project name (I used "CardValidator") and complete creating project. Then right click on newly created project and select New -> Axis2 Service From Java... 
Give any name you wish as class name (in my case "MyClassValidator") and select package from list (in my case "cardvalidator"). And Finish it. Now its done. You will find a sample service call hello:String.
Then your new service method will appear as a service. You can right click on it and test it.
