[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Tomcat 6 comet support in 4.2.2

[jon.brisbin]

I was wondering how I go about doing Comet inside a webapp by implementing the catalina CometProcessor interface? When I access a servlet that implements this interface, I get this JBoss-specific error:

java.lang.ClassCastException: org.jboss.web.tomcat.filters.ReplyHeaderFilter cannot be cast to org.apache.catalina.CometFilter

What do I need to do to get comet support in the Tomcat that comes with JBoss? Replace it with Jetty?

Thanks!
