Howdy,
Just started with the new EJB 3 stuff, so I'm guessing I've done something wrong. I just can't see what it is.
I'm getting ClassCastExceptions when trying to get the a Remote Session Bean in a JNDI lookup. It's failing on the cast to the GeoFeatureManager.
try {
| String geoFeatureManagerName = "motionbased/GeoFeatureManagerBean/remote";
|
| InitialContext ctx = new InitialContext();
| Object object = ctx.lookup(geoFeatureManagerName);
| GeoFeatureManager geoFeatureManager = (GeoFeatureManagerBean) object;
|
| this.geoFeature = geoFeatureManager.findGeoFeature(getGeoFeaturePk());
| } catch (NamingException e1) {
| e1.printStackTrace();
| throw new SQLException(e1.getMessage());
| }
The Remote Interface
| @Remote
| public interface GeoFeatureManager extends Serializable {
| ...
| }
|
The Implementation of it ...
@Stateless(name = "GeoFeatureManagerBean")
| @Remote( { GeoFeatureManager.class })
| @RemoteBinding(jndiBinding = "motionbased/GeoFeatureManagerBean/remote")
| public class GeoFeatureManagerBean implements GeoFeatureManager {
| private static final long serialVersionUID = 6211376611083502502L;
|
I read this http://wiki.jboss.org/wiki/Wiki.jsp?page=CommonHurdlesAndDifficultiesYouMayEncounterDuringEJB3Development that says to make sure you don't have the class in more than one jar. I've checked, and it only appears in one of my jars.
When I step through the code, it returns a $Proxy, which contains h, a StatelessRemoteProxy. Within the proxy it sees the appropriate jar. And in the EJBMetaData, it has the appropriate interface, GeoFeatureManager.
So, I don't really see what I'm doing wrong. Hopefully somebody else can point out my mistake.
Thanks!
