Ok Found the answer as to why this was not working. This may be trivial to seasoned users, but a hard catch for a newbie.
For components, such as the Header we have been talking about, the .java file AND the .tml file need to both reside in the components package. I had been putting the .tml file in the webroot and the .java for the component in components. Moved the .tml to components package and it works now.

No error, just no header rendered. ------------------------------------------- Here is my Header.java file: package try.tapestry.components; public class Header { public Header() { } } -------------------------------------------- Here is my Header.tml file: <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";> <body> <h1>This is a header</h1> </body> </html> -------------------------------------------- Here is my Start.tml <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd";> <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/> <title>Hello World Title</title> </head> <body> <t:Header /> Hello world. Start. </body> </html> ----------------------------------------------- Here is my Start.java package try.tapestry.pages; public class Start { public Start () { } } ------------------------------------------------- Here is the output when rendered (no header was inserted, just ignored. No errors.): <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd";><html><head><link href="/assets/tapestry/default.css" rel="stylesheet" type="text/css"><meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"><title>Hello World Title</title></head><body> Hello world.

Bob -----Original Message----- From: Howard Lewis Ship [mailto:[EMAIL PROTECTED] Sent: Friday, October 19, 2007 18:20 To: Tapestry users Subject: Re: Templates and t:body Tapestry mandates a certain organization to your classes. If you page class is org.example.pages.MyPage then your component class (here, Header) must be org.example.components.Header. The .pages. and .components. part is very specific to Tapestry, hard-wired into the framework. Those are packages that Tapestry scans at startup to locate page and component classes, and such classes must exist there (for Tapestry to perform runtime code transformation and hot class reloading).
