Hi Gavin,
Yes, I used myfaces/tiles in my project, and it is great. Now, I also want to
use facelets, but I don't know whether it is possible to keep the myfaces/tiles
and also use facelets functions. Thank you.

Petemuir and Gavin,
Thank you very much for your directions, I fixed my problem after removing
javax.faces.CONFIG and recoding my web.xml.
I have one more question, did anyone ever combine faces/tiles with facelets? Or
is it possible? Thank you.
Best regards,

As to changing List to SortedSet on JBoss 4.0.4. GA, I found that the dvdstore

| public class Order
| implements Serializable
| {
| ...
| List orderLines = new ArrayList();
| ...
| @OneToMany(mappedBy="
I have a problem after changing List to Set. Since the data type of JSF
dataTable should be List, Array or ResultSet, it is a little hard to change Set
back to List to be displayed by dataTable, especially for Seam @DataModel.
Anybody has some good idea? Thank you.

Hi Jboss experts,
Recently, I plan to use Seam on my project, but I immediately found that JBoss
proposed the new std framework of Web Beans. I am wondering whether the Web

Hi all,
We currently have a problem for merging two Tomcat servers to one, because the
two have different port number 4040, 5050. Since we do not want to combine the
two port right away(we need to notify customers), is it possible to use two

Hi all,
I found a little idea in the Hibernate in Action book, it is on the section of
Using a collection of components for a many-to-many association in Chapter 6.
It seems that I need to create a new class for the joint table. Any further
suggestion is appreciated.

"Writing a getFiles method in your stateless bean" means to create another
