Comet transport [Was: Re: Deploy Synapse on Tomcat?]

[Andreas Veithen <an...@skynet.be>]

Paul,

I looked into it and I think that implementing this should not be too  
difficult. The reason is that a CometProcessor servlet pretty much  
uses the same API as a normal servlet (i.e. HttpServletRequest/ 
Response with Input/OutputStream). The difference is in the way the  
servlet is invoked. Therefore the implementation could reuse a large  
part of the code in the existing AxisServlet. As you know, one can  
reuse code either by copy & paste or introducing appropriate  
abstractions. Since the first alternative is not really an option, we  
would have to refactor some parts of AxisServlet so that it becomes  
reusable for a CometProcessor implementation. Therefore we would need  
somebody who is familiar with the code and who is willing to take the  
responsibility to make the necessary changes (knowing that AxisServlet  
is one of the core components of the framework).
