Hi,
Try this link.
http://www.agileskills2.org/EWDT/chapters1-4.pdf These are the first 4 chapters in "Enjoying Web Development with Tapestry" by Ka Iok Tong (Book).
You will find it more interesting and easy.
after going through the chapters, it is better to get this book. Don't go for Tapestry in Action if you are a beginner.
Regards,
Nandhini
