NO! This is wrong! I must have misread "http://tapestry.apache.org/tapestry5/tutorial1/first.html"; where it says: 'Let's start with the template, which is stored in the webapp's WEB-INF folder. Tapestry component templates are well-formed XML documents.' I thought this meant the Start.tml should go in WEB-INF, but in fact it should be one level higher. > 2) Apparently there is a difference in OC4J packaging T5 classes in lib > vs. classes.
