[EJB 3.0] - Re: RC9 mappedBy and InheritanceType.JOINED problem
by supernovasoftware.com
GenericItem does not have a @MappedSuperclass. Adding this gets me past that error, but I then get the error at the bottom of this post and breaks my application in 4.0.4.
Did something change in the EJB3 spec that prevents me from using mappedBy on the property property of a superclass?
The following code appears in my State class.
| private Set<Coupling> couplings = new HashSet<Coupling>();
| @OneToMany(mappedBy="state")
| public Set<Coupling> getCouplings() { return couplings; }
| public void setCouplings(Set<Coupling> couplings) { this.couplings = couplings; }
GenericItem has the following and Coupling extends GenericItem
private State state;
| @ManyToOne
| public State getState() { return this.state; }
| public void setState(State state) { this.state = state; }

[JBoss Portal] - Re: Portal Request Architecture
by jboss＠biancashouse.com
Tom,
you mentioned that I should look at the Seam portal demo, which is supposed to show the use of Seam + Portlet + Facelet, but the view files are JSP. The non-portal demo of Booking uses xhtml. Is the seam portal demo using Facelets ?
Encouraging development:
I had a little browse inside the Nuxos-5 ear, because it looks like it is using the whole combination of sought after technologies; i.e. seam + portlet + facelets + AJAX4JSF + jBPM.
Perhaps their xml config files will provide some insight into how these APIs can work/fit together...
BTW - JSF-Bridge - it's a proposed standardising of how the JSF and Portlet request lifecycles should be integrated. I assume JBoss are a player in this effort ?
Thanks for the feedback - it really is appreciated.
Ian
