I think the question being asked here is "will the Struts controller functionality (currently implemented in ActionServlet) be implemented as a javax.servlet.Filter from the Servlet 2.3 API?" It's a pretty interesting question. Had the Servlet 2.3 API been available when Struts was originally designed, it's a pretty sure bet that I would have implemented the controller as a Filter instead of as a Servlet. This would have made possible some interesting approaches to using the Struts controller in front of (or in front of part of) existing applications that are being migrated to Struts, as well as the "multiple controllers per webapp" paradigm that we are currently discussing. However, that's not what happened. Struts is currently based on the facilities of Servlet 2.2 and JSP 1.1, because that provides support on the very broad range of application servers that support these APIs. I feel that we ultimately want to migrate to Servlet 2.3 / JSP 1.2 to take advantage of the new facilities -- the quesion is, when? We certainly need to continue to support the ability to run Struts based applications on a Servlet 2.2 / JSP 1.1 platform for the forseeable future. However, there are many compelling features of the next generation APIs that are worth supporting. I'd like to see us explore taking advantage of those capabilities by offering enhanced (or alternative) implementations of the basic Struts controller functionality based on the new APIs. What do the other developers think? Are there enough Servlet 2.3 / JSP 1.2 environments available (obviously, I will be using Tomcat 4 for this, since I'm pretty intimiate with its internals :-) to make development *and deployment* of Servlet 2.3 / JSP 1.2 based applications useful, or is it still a little too early? Even if it's too early, we can start exploring those sorts of ideas so that we're ready when the platforms are readily available.
