[jboss-user] [JBoss Seam] - Re: Integrating Seam and Icefaces

[jerome_082006]

Hello,

Thank you very much.

I tried to add this:
<application>
  |  <variable-resolver>
  | 	org.jboss.seam.jsf.SeamVariableResolver
  |  </variable-resolver>
  |  <locale-config />
  | </application>

to my faces-config.xml and this is what I get:

I am probably missing something in my configuration files or using inappropriate jar files.

I also tried to add a Seam servlet filter (org.jboss.seam.servlet.SeamServletFilter) around the Persistent Faces Servlet.

I would like to understand how these two frameworks are supposed to interact with one another. Could you please explain me (basically) how it should work ? which servlet is to be called first ?

Regards,
Jerome.
