Cannot get value for expression

[Edney Imme <ed...@gmail.com>]

Hello,

I need more help.

I get the following error message.

javax.servlet.ServletException: ServletException in
'/pages/consulta/result.jsp': Cannot get value for expression
'#{resultPage.articleNumber}'
	javax.faces.webapp.FacesServlet.service
(FacesServlet.java:154)
	org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:173)
	org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java
:77)
	org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:147)


In faces-beans.xml I had do that:

    <!-- Delivery schedule -->
    <managed-bean>
        <managed-bean-name>resultPage</managed-bean-name>
        <managed-bean-class>
        com.edney.resultPage</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
    </managed-bean>

Why this error message?

Is there a "cause" exception shown for the exception you pasted above?

This looks ok, so I suspect the problem is either in the Hibernate 
integration (eg no database connection), or the getArticleNumber method 
is throwing an exception.
