Problems with @Interceptors in JBoss 4.0.4 GA
Hi There!
I just migrated my whole EJBs to JBoss 4.0.4 GA and now get those exceptions...

For installing JBoss I used the jboss-4.0.4.GA-Patch1-installer.jar and selected the EJB3 configuration.
I figured out, that by commenting out the @Interceptors annotation the deployment functions properly. I want to know, if something with the Interceptors has changed regarding to the new JBoss / EJB stuff.
Here are the "interceptor class" and my session bean. Maybe you've some hints for me. I couldn't find anythings about that in the specs.
CustomerAccountHomeBean
import static javax.ejb.TransactionAttributeType.REQUIRED;
import javax.annotation.EJB;
import javax.annotation.Resource;
import javax.ejb.Interceptors;
import javax.ejb.Stateless;
import javay.ejb.config.Config;
import javay.ejb.config.ConfigListener;
import javay.ejb.config.ConfigResource;
import javay.ejb.config.PropertiesConfigurator;
@Stateless
@Interceptors(ConfigListener.class)
@ConfigResource(type = PropertiesConfigurator.class, resource = "/config.properties")
public class CustomerAccountHomeBean implements CustomerAccountHomeLocal,
CustomerAccountHomeRemote
{
protected @Resource(mappedName="java:/Mail")
Session mailSession;
public @Config
String transportProtocol = "smtp";
protected @EJB
Velocity velocity;
// ...some Methods...
}
ConfigListener
public class ConfigListener
{
@PostConstruct
public void init(InvocationContext invocationContext)
{
Class< ? > clazz;
ConfigResource configResource;
Configurator configurator;
String resource;
InputStream inputStream;
Object object;
object = invocationContext.getBean();
try
{
clazz = object.getClass();
if (clazz.isAnnotationPresent(ConfigResource.class))
{
configResource = clazz.getAnnotation(ConfigResource.class);
configurator = configResource.type().newInstance();
resource = configResource.resource();
assert resource != null;
inputStream = clazz.getResourceAsStream(resource);
assert inputStream != null;
configurator.load(inputStream);
walk(configurator, clazz, object);
for (Class< ? > cl : clazz.getClasses())
{
walk(configurator, cl, object);
}
}
}
catch (InstantiationException e)
{
// TODO Logging
e.printStackTrace();
}
catch (IllegalAccessException e)
{
// TODO Logging
e.printStackTrace();
}
catch (IOException e)
{
// TODO Logging
e.printStackTrace();
}
}
private void walk(Configurator configurator, Class< ? > clazz, Object object)
throws IllegalArgumentException, IllegalAccessException
{
for (Field field : clazz.getDeclaredFields())
{
if (field.isAnnotationPresent(Config.class))
{
configurator.config(field, object, field
.getAnnotation(Config.class));
}
}
}
}
