Comet while migrating to Tomcat 7

[Ronald Klop <ro...@base.nl>]

Hello,

I'm trying Tomcat 7. The Comet classes have been moved from the org.apache.catalina package to the org.apache.catalina.comet package. That is fine by me. But for deployment reasons it would be easy if I can deploy the same war on Tomcat 6 and Tomcat 7. In that way I don't need a turn-key upgrade of my Tomcat servers.

Is there a way to make it dynamic which package is used? Something like a Proxy or some other trick I don't know yet.
How do others do this?

Ronald.

Hi,

My problem is not changing the code, but I now have to maintain two versions of the code. One with import org.apache.catalina.CometProcessor and one with org.apache.catalina.comet.CometProcessor. And Eclipse has to resolve both of them.

Look. I can now choose to develop against Tomcat 7, but when I have a problem with it in production in a couple of weeks I would like to have the ability to switch back to Tomcat 6 easily.

Somehow we wil manage this, but I was wondering how other people are doing this migration. Maybe I'm missing something clever.

In the end I'm expected to switch to ServletRequest.doAsync(), or am I not?

Ronald.

This wouldn't require code changes?

Recompile, or produce two versions of the app.  :s
