Hedinges, I did it this way. (1) Create a google app engine application using the eclipse plugin (2) Add tapestry-core, annotations, ioc, sl4j, log4j and all needed jars to the war/WEB-INF/lib folder (3) Write your tapestry helloworld program as you like (make sure you changed the web.xml to include tapestry filter)
The above steps are common and you would have done it as well. Now if you run this application now as a google web application (run as/debug as>google web application), you will get the error that you posted. Instead use jetty launcher and configure the webapp folder path to your 'war' folder path... now launch your app in jetty and everything will work fine. Since it is still a google app engine project in eclipse, you can use the eclipse plugin to upload it to your.appspot.com - keerthy On Sun, Apr 26, 2009 at 9:20 PM, hedinges <xcos...@gmail.com> wrote:
