Step by step guide to create Singleton design pattern with Java
http://www.techcubetalk.com/index.php?page=Singleton java design pattern
The main purpose is that if we have to use a resource then we can create a singleton class which can only access the resource and by making this instance available to other threads or any part of the application we can make sure that unnecessary objects are not getting created for accessing the resource.
Another purpose is that we have some utility classes which are being used by other java classes to do some calculations etc. Now if we make the utility class a singleton class then all objects and all parts of the application can use this one instance of the utility class and no extra instaces are required. There are lots of other uses also. Java > Tips and Tutorials > Development Jun 13, 2008 java_guru send email to java_guru

Product Map (A-Z) for X-Cart provides an alphabetical listing of your products for increased search engine spidering and easy product browsing. For stores with many products, site maps are not ideal, as most SEO gurus recommend not to display more than 50 links per page. Product Map (A-Z) for XCart solves this problem by providing easily spiderable product links, sorted alphabetically, and then broken into multiple pages, with featured products listed first - so they are weighted heavier by search engines.

server-side control architectures such as Java ServerFaces (JSF) or Struts, a majority of the control events must be handled on the server side to update the state of the control. For every user event, the entire page data is sent back to the server as part of the form submission. Even data that has not changed or is not affected by the user event is sent to (and back from) the server. It is obvious that handhelds, overburdened Web servers, and possibly wireless networks would benefit from the avoidance of redundant data processing in these instances; the question is how to implement a solution.
