I successfully integrated the GWT Server Library into my GWT 2.0 app
and had a working example in hosted mode. Due to a suggestion in the
server library documentation I then added the following to my web.xml.
<filter>
<filter-name>NoCachingFilter</filter-name>
<filter-class>org.gwtwidgets.server.filters.ResponseHeaderFilter</
filter-class>
<init-param>
<param-name>Expires</param-name>
<param-value>Di, 1 Jul 2008 12:00:00 GMT</param-value>
</init-param>
<init-param>
<param-name>Cache-Control</param-name>
<param-value>no-cache, must-revalidate</param-value>
</init-param>
<init-param>
<param-name>Pragma</param-name>
<param-value>no-cache</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>NoCachingFilter</filter-name>
<servlet-name>stream</servlet-name>
</filter-mapping>
Shortly thereafter I was unable to load my GWT app in hosted mode.
The html page loads but I get the error shown below in the console
when I paste the URL into the browser and go.

The file exists in the correct location under under the war directory
as specified by the path shown in the error message. Post error, I
did the following in this order at each step hoping it would fix the
issue.
1) Removed the xml filters shown above form web.xml.
2) Performed a GWT compile.
3) Rebooted my computer.
4) Cleared the browser cache of both I.E. and Chrome.
5) Installed Firefox (never before installed on this computer)
None of these steps helped. Helpful thoughts appreciated.
