WEB2795: Marking servlet org.apache.catalina.INVOKER.crn as unavailable

Tool:Cognos 8/Oracle 10g/Sun One Web Server 6.1/BEA Weblogic 8.1 SP3.

I see the following error many times in the cognos web server log file. What does it mean ?

xxx.xxx.xxx.xxx --IP,s

Try commenting out the following lines from webserver config\default-web.xml:

<!-- The mapping for the invoker servlet -->

<!--

<servlet-mapping>

<servlet-name>invoker</servlet-name>

<url-pattern>/servlet/*</url-pattern>

</servlet-mapping>

-->

No change seen after commenting out.

I don't have the exact setup as yours (particularly Cognos ReportNet). But, I had simulated another way and checked that commenting out those lines worked fine: no error after stopping and restarting the server.
