Ted, I can add a little to the link you mentioned. Several years ago when Struts was young and hip ;) we developed an app using Struts + Weblogic/EJB (aw, entity beans) + IBM Voice Response Server (for VoiceXML). Application has the following features: * renders regular HTML * delivers WML output * delivers voice responses via VoiceXML + voice server (we used IBM Voiceresponce, but then switched to much smaller and cheaper in-house VoiceXML browser); gets DTMF input. We do not use voice recognition or voice generation. We use pre-recorded voice sequences in sound files, and touch-tone DTMF input. For these three categories we have common EJB/business/Struts actions, but different JSPs. When client hits the application for the first time, we check "accepts" header and set medium to either WEB, WAP or IVR. Then startup action forwards to to an actual welcome action corresponding to the medium. We have three types of action mappings for each medium, like <action path = "/login" type = "acme.struts.LoginAction"> <-- for html <action path = "/vlogin" type = "acme.struts.LoginAction"> <-- for voice xml <action path = "/wlogin" type = "acme.struts.LoginAction"> <-- for wap Each action mapping has its own JSPs which is reasonable since markup is so different. Each JSP contains links only to actions for its own medium, so after "welcome" action detects the medium, all interaction happens within actions and JSPs for a particular medium. This is a pretty cool application, a lot of stuff there: EJB, WebLogic, clustering, telephony, sound-processing, WML markup, WML gateway interaction, VoiceXML markup, VoiceXML browser, ... Yep, this was a great project.
