| | | - Newbie Help. Do I have SEAM deployed? | - Newbie Help. Do I have SEAM deployed? 2007-08-08 - By birwin

I started fiddling with SEAM (2.0.0BETA1) today, but I don't think I have
installed it correctly (Installing on JBoss 4.2.1.GA).
I am unable to display data in my UI (Its a JSP). Each time I load the web page
, the input field is empty, but my backing bean has data. The backing bean has a
value assigned to its property on instantiation (See the java code below). If I
add a "managed-bean" entry to my faces-config.xml, it works fine and the number
appears in my input field. I thought I did not need "managed-bean" entries in
my faces-config.xml file if I was using SEAM. From my searches on the Internet,
it appears that I am not using SEAM, but the plain JSF. I have deployed the
Seam JAR file in the WEB_INF/lib directory of my war file. Attached are my
faces-config, web.xml, JSP and Java class files.
My java class has the Name and Scope annotations, and I have included the phase
-listener entry in my faces-config.xml file in addition to including the
listener-class entry in my web.xml file. When I deploy to my JBoss server, it
appears SEAM kicks in. I see row after row of "INFO [Component] Component: org
.jboss.web.session, scope: SESSION, type: JAVA_BEAN, class: org.jboss.seam.web
.Session" type messages.
Any ideas what I did wrong?
faces-config.xml file:
<faces-config>
<phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener>
</faces-config>
web.xml file:
<web-app>
<!-- Listeners -->
<!-- Seam -->
<listener-class>org.jboss.seam.servlet.SeamListener</listener-class>
<!-- JSF -->
<listener-class>com.sun.faces.config.ConfigureListener</listener-class>
