Can you rephrase the question? What are you asking?

In general, you *have* to use web.xml. You don't have a choice. You use it to declare key aspects of your web application.

we give the <url-pattern> of our servlet in web.xml, and i read somewhere that we can also give this into the servlet itself using annotations, and we can easily change the url-pattern from class itself, no need to go for web.xml..

also i want to know what other things i can do in web.xml??
(ie. we can do error handling.)

1-par application should have one web.xml file.
2-you can able to define the welcome pages.
3-when server going to deployed any J2EE application it will look for only web.xml first
3-all Servlet entry should we present in this file
4-you can also add filter class can also mentioned dependency.
7-EJB reference
