The error i'm facing is...

exception

Hi Friend,

Have you done the servlet mapping in web.xml?
If not, do it as follows:

<servlet>
<servlet-name>Ex1</servlet-name>
<servlet-class>Ex1</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Ex1</servlet-name>
<url-pattern>/Ex1</url-pattern>
</servlet-mapping>

For more information, visit the following link:
