OK, with the help of the SeamlessViewHandler at http://www.ilikespam.com/blog/faking-a-postback-with-jsf-facelets (with the addition of a call to initialize(context) at the beginning of buildView()), I have gotten much further. I believe I am actually getting to the page now, but I am getting lots of taglib exceptions.

Then there was another one for the jsf-facelets.jar file in myApp.ear/myApp.war/WEB-INF/lib/jsf-facelets.jar.
Then there was a pair of those for jsf-html.taglib.xml, jsf-ui.taglib.xml, jstl-core.taglib.xml, and jstl-fn.taglib.xml.
seam-mail.taglib.xml and seam-pdf.taglib.xml loaded Ok from war/WEB-INF/lib/jboss-seam-mail.jar and war/WEB-INF/lib/jboss-seam-pdf.jar, respectively, but s.taglib.xml failed to load from jboss-seam-ui.jar because:

The following also failed for similar "must be an instance of com.sun.facelets.tag.TagHandler" reasons:
a4j.taglib.xml on org.ajax4jsf.taglib.html.facelets.AjaxListenerHandler
| ajax4jsf.taglib.xml on org.ajax4jsf.taglib.html.facelets.AjaxListenerHandler
| rich.taglib.xml on org.richfaces.taglib.DragSupportHandler
| richfaces.taglib.xml on org.richfaces.taglib.DragSupportHandler
Am I barking up the wrong tree? Shouldn't all this stuff already be initialized? When I first hit my web app, my log spits out a bunch of "loadImplicit" errors about each one of these taglibs, but no stackdump. Do I need to somehow change the classloader I'm working under?
