Gzip Filter in web Application

[JavaFaces]

Please guide me where to put my Gzip filter in my web directory structure.
I am listing my web.xml entry for the filter. Currently my filter is sitting in a filter package. when i run the app it gives an error saying
Error:
-------
FAIL - Application at context path /CofeeAdvice could not be started

please guide me what to do, if i remove my xml entry for the filter then my app runs otherwise it gives above error....Thanks

<filter>
<filter-name>GzipFilter</filter-name>
<filter-class>com.example.filter.GzipFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>GzipFilter</filter-name>
<url-pattern>/*.jsp</url-pattern>
</filter-mapping>

Try <url-patttern>*.jsp</url-pattern>

If it still doesn't work, may I suggest you try an alternative compressing filter which I wrote:
http://sourceforge.net/projects/pjl-comp-filter

It is fully documented and should perform better than GZIPFilter.
