Custom Servlet Error

[matkapx]

Hi Friends,
For google visualization api i am tryin to create a CustomServlet for DataSource.
The think is when i try to define my CustomServlet named Tasking Seam gives Error with the URL
http://localhost:8080/seamfinal/tasking


web.xml configuration:

<servlet>
  <servlet-name>MyTasking</servlet-name>
  <servlet-class>Tasking</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>MyTasking</servlet-name>
  <url-pattern>/tasking</url-pattern>
</servlet-mapping>

components xml :
<web:context-filter url-pattern="/tasking/*" />

I also tried to web.xml servlet as ,
<servlet>
  <servlet-name>MyTasking</servlet-name>
  <servlet-class>org.domain.seamfinal.servket.Tasking</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>MyTasking</servlet-name>
  <url-pattern>/tasking</url-pattern>
</servlet-mapping>
But nothing changed
Below you can find the full stack.
