In a Sun free ePractice question:


The aswer is letter B... Ok, I agree about that.
But why the letter C is wrong?! The param-value isn't passed with a parameter to the Servlet?

if i'm not wrong, the servlet is initialized only once and get a servletConfig
that contain the name=value pairs of init parameters.
so C is wrong because:
1. only the servletConfig get the name-value parameters.
2. the servlet doesn't get the servletConfig each request, only upon initialization...

Yeas...
I think that you're right. This param is configured at Servlet just at when it is initialized...

Thanks!

This url-pattern tells to container how the servlet will be called.

For example:

http://www.mysite.net/shop/action1
http://www.mysite.net/shop/action23
http://www.mysite.net/shop/123

All url's will use the same servlet mapped by servlet-name.
In that case org.myorg.ShoppingServlet.

The actions after the ...shop/ (action1, action23, 123, ...) we can get them in servlet code and use like a flag to choose the action required...
