just like the other question: Read the documentation. Tiles are a core part of Struts, and we are not doing Struts here. Again read the documentation and discover that Seam uses (amongst other things) JSF and Facelets which are far more powerful than Tiles, although tey have comparable concepts.
READ THE DOCUMENTATION !!!
Knowing that the seam is very powerful, that nobody doubts the issue is I have a project done using tiles do I need to convert it gradually to seam ... I wonder if anyone has used tiles and seam simultaneously.
Thanks for the help.
