I’m upgrading from 4.5.2 to 7.0.3. Since the upgrade, I have an interceptor
that fails and consequently session beans can’t be invoked. I found the same
error when I tried to upgrade to 4.6.0.2. Was there a JNDI change between 4.5.2
and 4.6.0.2?

The NPE line is indicated in this source...
public class UsernameCacheRefresher {
@Resource
private javax.ejb.SessionContext context;
private static final Logger logger =
LoggerFactory.getLogger(BaseService.class);
@AroundInvoke
public Object refreshUsernameCache(InvocationContext ic) throws
Exception {
Principal callerPrincipal = context.getCallerPrincipal(); <<<
Line 38. NPE happens here.
if (callerPrincipal != null) {
UsernameCache.setThreadUsername(callerPrincipal.getName());
}
else {
// Is this even possible? Isn't there a default
principal of guest (OpenEJB) or anonymous (JBoss)?
logger.error("WATCH OUT - UsernameCacheRefresher found
callerPrincipal is null!!!!!!!!!!!!!");
UsernameCache.setThreadUsername(null);
}
return ic.proceed();
}
}
Here’s an example of how it gets used…
@Stateless
@Local(IEmailManagerServiceLocal.class)
@Remote(IEmailManagerServiceRemote.class)
@Interceptors({ UsernameCacheRefresher.class })
public class EmailManagerService extends BaseService implements
IEmailManagerServiceLocal, IEmailManagerServiceRemote {
…
}
Thanks in advance,
Geoff
