Hi,
I am running jboss-3.2.1 with tomcat-4.1.24 and have configured the following filter scheme in my web.xml:
<web-app>
<filter>
<filter-name>UISCompressionFilter</filter-name>
<filter-class>com.unisys.framework.control.UISCompressionFilter</filter-class>
<init-param>
<param-name>compressed</param-name>
<param-value>true</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>UISCompressionFilter</filter-name>
<servlet-name>LongServlet</servlet-name>
</filter-mapping>

<filter-mapping>
<filter-name>UISCompressionFilter</filter-name>
<url-pattern>/TesteDPR.html</url-pattern>
</filter-mapping>

<filter-mapping>
<filter-name>UISCompressionFilter</filter-name>
<url-pattern>/long.jsp</url-pattern>
</filter-mapping>
...
My filter works fine when accessing a servlet or jsp page but when I try
to get html files, the following exception is thrown:
Please Help !!!

Just in time, take a look at what servlet 2.3 spec says about filters and static content...
"Filters can be associated with groups of servlets and static content using the url-pattern style of filter mapping:
<filter-mapping>
<filter-name>Logging Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Here the Logging Filter is applied to all the servlets and static content pages in the web application, because every request URI matches the ‘/*’ URL pattern. When processing a filter-mapping element using the url-pattern style, the container must determine whether the url-pattern matches the request URI using the path mapping rules defined in Chapter SRV.11.
Thanks, Juarez
