hello daniel,
i would like to suggest other solutions.
i think you are familiar with the common ways of handling navigation
(summarized - e.g. if you use the "from-outcome" approach an action-method
returns the outcome or you use a static string within your page - with this
approach only these outcomes are used for navigation)
-> if your "init"-method is not an action method (it doesn't sound like one)
- you should consider alternative solutions.
--- just a general information before we start ---
with this additional information i don't refer to the solution you are
having in mind!
basically you can manually navigate e.g. with:
FacesContext.getCurrentInstance().getApplication().getNavigationHandler().handleNavigation(
... );
or with:
FacesContext.getCurrentInstance().getExternalContext().redirect(
... );
however, be careful with these mechanisms - they don't work at any point of
your application and you risk to "break" your application if you misuse
these mechanisms.
---
if you don't like to use security extensions such as Acegi you have to
implement custom mechanisms to provide login pages and to avoid initial
actions within your bean. in that case i would suggest more generic
solutions - e.g. a custom PhaseListener or a custom NavigationHandler.
to summarize my suggestion: use/implement a mechanism which takes place
before your init-method gets executed.

gerhard
