I tried the second option, and it doesn't seem to work either...:)
I created a specific exception which is thrown from the constructor of the
backing bean and mapped it in web.xml to an error page.
Do you think tiles may have something to do with it ?
This is part of my entry in tiles-defs:
<definition name="/erreurGenerique.tiles" extends="rootLayout">
.....
</definition>
And this is from my web.xml
<error-page>
<exception-type>com.hydroquebec.lsw.ExceptionErreurGenerique</exception-type>
<location>/erreurGenerique.jsp</location>
</error-page>
(I know there is a diff between the *.tiles and *jsp suffixes, but I believe the mapping is done via the JspTilesViewHandlerImpl view handler)
My context root is "lsw". I've tried every variation possible for the path
in the location tag:
/erreurGenerique.jsp
/faces/erreurGenerique.jsp
/lsw/faces/erreurGenerique.jsp
etc....
and it simply wont't catch.
Could anyone give me example of a Backing Bean constructor that loads info
from a database and contains code which redirects a user to an
error page should the database link be broken ?
Thanks in advance,
Mark

Objet : Re: Error handling & redirecting from BB constructor possible ?
Well, this should work. Look at the JSF 1.1 API for further details, but here are some things that could be going wrong:
1. FacesContext.getCurrentInstance().getExternalContext().redirect(String)
already called FacesContext.responseComplete(), so you don't need to call FacesContext.renderResponse(), though this shouldn't matter 2. FacesContext.getCurrentInstance().getExternalContext().redirect(String)
needs the absolute URI you are redirecting to. If you provide the wrong URI, I don't know what will happen.
If you're still dead set against using
FacesContext.getCurrentInstance().getExternalContext().redirect(String)
you could just set up an error page in your web.xml for the exception, though this may not be optimal.
