seam cannot reference EJB, why?
Hi
I want to refer to an EJB from JSF without backing bean in the web container, but I got the following exception:
javax.faces.el.PropertyNotFoundException: Error testing property 'departureAirport' in bean of type null
my JSP refer to the EJB and looks like this
<h:inputText id="departureAirportInput" value="#{bookingBean.departureAirport}">my EJB is specified as Seam component and looks like this
@Stateful
@Name("bookingbean")
@Local(Booking.class)
public class BookingBean implements Booking, Serializable{
..
private String departureAirport;
..
public String getDepartureAirport() {
return departureAirport;
}
public void setDepartureAirport(String departureAirport) {
this.departureAirport = departureAirport;
}
..My faces.config integrates Seam in JSF and looks like this
<faces-config > <lifecycle> <phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener> </lifecycle> ..
My components.xml configure Seam in JSF and looks like this
<?xml version="1.0" encoding="UTF-8"?>
<components xmlns="http://jboss.com/products/seam/components"
xmlns:core="http://jboss.com/products/seam/core"
xmlns:security="http://jboss.com/products/seam/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=

http://jboss.com/products/seam/security http://jboss.com/products/seam/security-1.2.xsd
http://jboss.com/products/seam/components http://jboss.com/products/seam/components-1.2.xsd">

<core:manager conversation-timeout="120000"

conversation-is-long-running-parameter="clr"/>
<!-- <core:transactionListener/> -->
<!--<core:ejb installed="@embeddedEjb@"/> -->
<security:identity authenticate-method="#{authenticator.authenticate}"/>
</components>My web.xml integrates Seam in JSF and enables Seam exception handling and looks like this
<web-app.. <listener> <listener-class>org.jboss.seam.servlet.SeamListener</listener-class> </listener> <servlet> <servlet-name>Seam Resource Servlet</servlet-name> <servlet-class>org.jboss.seam.servlet.ResourceServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Seam Resource Servlet</servlet-name> <url-pattern>/seam/resource/*</url-pattern> </servlet-mapping> <filter> <filter-name>Seam Filter</filter-name> <filter-class>org.jboss.seam.web.SeamFilter</filter-class> </filter> <filter-mapping> <filter-name>Seam Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> .. </web-app>
The ejb.jar declares the Seam interceptor and register it to the EJB and look like this
<?xml version="1.0" encoding="UTF-8"?> <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd" version="3.0"> <interceptors> <interceptor> <interceptor-class>org.jboss.seam.ejb.SeamInterceptor</interceptor-class> </interceptor> </interceptors> <assembly-descriptor> <interceptor-binding> <ejb-name>*</ejb-name> <interceptor-class>org.jboss.seam.ejb.SeamInterceptor</interceptor-class> </interceptor-binding> </assembly-descriptor> </ejb-jar>
What is my mistake?
Note that I can refer to the EJB from JSF using the standard EJB lookup mechanism either local or remote. I use JBoss 4.0.5, JSF 1.0, EJB 3.0 and Seam 1.2.1GA.
The whole stack trace looks like this
