running Adobe ColdFusion 9 on CF8 with simple url rewriting

At work, we use are transitioning to Adobe ColdFusion 9. Our local development is multiple instances created with an Adobe ColdFusion 8 installer. It was very easy to get an ACF9 instance going. We created a ACF9 war and used that when creating a new instance in the ColdFusion administrator. I noticed simple friendly urls like index.cfm/myController/myAction wasn't working in CF9. It came down to uncommenting a section in the web.xml for ACF9(SES).

For me, the web.xml was C:\JRun4\servers\ACF9\cfusion.ear\cfusion.war\WEB-INF\web.xml . Search for SES (around line 436) and then remove the comments around:

<servlet-mapping id="coldfusion_mapping_6">
<servlet-name>CfmServlet</servlet-name>
<url-pattern><em>.cfml/</em></url-pattern>
</servlet-mapping>
<servlet-mapping id="coldfusion_mapping_7">
<servlet-name>CfmServlet</servlet-name>
<url-pattern><em>.cfm/</em></url-pattern>
</servlet-mapping>
<servlet-mapping id="coldfusion_mapping_8">
<servlet-name>CFCServlet</servlet-name>
<url-pattern><em>.cfc/</em></url-pattern>
</servlet-mapping>
