ServletConfig Object

[chintan ramavat]

Hello Ranchers !

I am not getting one bullet in HFSJ (KB) book. In ServletConfig object they have given that, ServletConfig Parameters are configured in the DD(deployment descriptor). Please any body could light on the point, I am confused about the which parameters of ServletConfig there are trying to explain. Is that the one for Database connection / Bean look parameters ?? or something else.


- Thank you

Configuration parameters can be used for anything you want. They are simply name/value pairs that make sense to your web app or to a particular servlet.

[Christophe Verré]

For example, you could have a servlet looking like this :

<servlet>
<servlet-name>SimpleServlet</servlet-name>
<servlet-class>servlet.SimpleServlet</servlet-class>
<init-param>
<param-name>defaultColor</param-name>
<param-value>blue</param-value>
</init-param>
</servlet>

You'll get the "defaultColor" parameter via your ServletConfig's getInitParameter.

ServletConfig object is used by the Servlet Container to pass information to the Servlet during it's initialization. Servlet can obtain information regarding initialization parameters and their values using different methods of ServletConfig class.Initialization parameters are name/value pairs used to provide basic information to the Servlet during it's initialization like JDBC driver name, path to database, username, password etc.

[Raghavan Muthu]

If you want to configure the parameters and their values for a particular servlet, then you can go for ServletConfig. And you can retrieve them using the API with respect to the ServletConfig object inside that Servlet (for which you had configured in web.xml).


Hope this helps!

If you tell me what page this bullet is on, I will try to explain what they mean and how it relates to the exam :-)
