Right now, some of these things are being addressed by two initiatives. This is not to say these are the only possible solutions, simply what people have already started. I personally think both solutions are quite good, and any help anyone can offer would be appreciated.
First, there is Oleg's service manager, which could be used to plug in things like the Validator without loading another servlet or subclassing ActionServlet. As Oleg mentioned, the current work is in the contrib folder of the nightly build. Second, there is Craig's workflow package. This could help with a number of the multi-request sequencing (workflows) that people stuggle with now. There is some background on this here: http://jakarta.apache.org/struts/proposal-workflow.html The code repository is over in the Commons sandbox right now. I also worked the workflow demo into the Struts-Simple application (which is no longer that simple ;-). http://husted.com/struts/resources/struts-simple.zip Here, I think the next step is working on loading multiple Activities into the Registyr. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel +1 716 737-3463 -- http://www.husted.com/struts/ Bill Boland wrote: > > Hello all. > > I'm just getting to know Struts so please bear with me.
