Hello everyone my
last post one small HelloWorld Example I am showed in the video. This just for awareness
of the servlet based application. In the last I didn’t mention deployment descriptor
information in that now I am trying to give here deployment descriptor types
and what is the use of deployment descriptor.
Deployment Descriptor
is a component in Java EE application that describes how a web application
should be deployed. It is an xml file provided with each module of the
application. It describes the configuration information for that module. It must
e placed in WEB-INF directory, directly under the web application root. There are
different kinds of deployment descriptor. Hey common I am giving these
information into video while reading some people may not interest just simply relax
and see video is enough that the reason I am giving here video why your late
let see the video
Like that we can add the
following information in deployment descriptor.
<servlet>
<servlet-name>ShowRequestHeaders</servlet-name>
<servlet-class> ShowRequestHeaders</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> ShowRequestHeaders</servlet-name>
<url-pattern>/req</url-pattern>
</servlet-mapping>
</web-app>
Add more number of deployment
descriptor elements while using EJB in the application.
Next post on Request and
Response Headers…………….
