---------------------------------------------------------------
I managed to create some almost-working Injector for both Java EE and Spring.
EJBs and Spring Beans get injected with this.
Almost-working because I get serialization exceptions - I don't know why Wicket
needs the class serializable as the classes from Java EE injector and Spring
injector are not and they work. Problem appears with any @SpringBean declared
in page class.
If anyone is able to correct it so that no serialization exceptions are thrown,
feel free.
in Application.init():
{noformat}
addComponentInstantiationListener(new SpringComponentInjector(this));
addComponentInstantiationListener(new JavaEEComponentInjector(this,
createNamingStrategy()));
final SpringAndJavaEeInjector springAndJavaEeInjector = new
SpringAndJavaEeInjector(this, new StandardJndiNamingStrategy()); // I use my
own naming strategy, StandardJndiNamingStrategy is the default
InjectorHolder.setInjector(springAndJavaEeInjector);
