Replacing Oracle's Web Listener?

Does anybody know if it is possible to replace Oracle's Web Listener with a different Web Server, say NCSA's HTTPd Web Server?

If anybody has done this, did they have to do any re-configuration or setup on NCSA's web server so that it could talk to Oracle's Web Agent (to access stored procedures in the database)?
