[jboss-user] [JBoss Seam] - How to programatically create a seam component in a filter?
With seam 1.2.1, is it possible to create a seam component in a servlet filter?
If so how to do it?
In web.xml, I declare a filter after all other filters 9seam, jsf, etc...)
In components.xml:
| <component name="test.utilisateur" auto-create="true"
scope="session" class="com.saq.pp.metier.modele.Utilisateur"/>
|
In the servlet filter class, I have:
| public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain)
throws IOException, ServletException {
| chain.doFilter(req, resp);
| Utilisateur cx = (Utilisateur)
Component.getInstance("test.utilisateur");
| }
|
This result in the following exception:
| java.lang.IllegalStateException: No application context active

I have the same results with Component.getInstanceFromFactory()
