Filter Setup

I am having trouble setup a filter to function on only my jsp files. Below is what i have in my web.xml file. But it does not function. How do i specify this correctly?

<filter>
<filter-name>SemestreSelectedFilter</filter-name>
<filter-class>ies.SemestreSelectedFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>SemestreSelectedFilter</filter-name>
<url-pattern>/*.jsp</url-pattern>
</filter-mapping>

Thanks

what is not working?

How do you know your filter is not being invoked?

Make sure you are using a servlet engine (Tomcat 4.0 and greater or a servlet engine that supports Servlet 2.3 spec) that supports Filters.

When i use "/*.jsp" it does not invoke the filter for any files. I know it works because when i change it to "/*" it functions on all the files, including the images in the sub-directory.

Perhaps it´s due to me calling url-pattern and not specifying a valid pattern? Or is "/*.jsp" a valid url-pattern?

have you tried just this:

<filter-mapping url-pattern="*.jsp" filter-name="ies.SemestreSelectedFilter" />

or

<filter-mapping url-pattern="/*.jsp" filter-name="ies.SemestreSelectedFilter" />

I have tried *.jsp.

I will try now /*.jsp and */*.jsp

<url-pattern>*.jsp</url-pattern>
has always worked for me. it could be that there is already a 'default' filter in place defined earlier in the web.xml file.
