Illegal start of expression for Annotations

Question

I am using Ant to build, I'm getting these errors:

Buildfile: ...\build.xml
clean:
  [delete] Deleting directory D:\IdanWorkSpace\ECMSEJB\classes
ejb.compile:
  [mkdir] Created dir: D:\IdanWorkSpace\ECMSEJB\classes
  [javac] Compiling 26 source files to D:\IdanWorkSpace\ECMSEJB\classes
  [javac] ...\src\com\mirs\ecms\mdb\ECMSDispatcherMDB.java:28:   illegal start of expression
  [javac] })
  [javac] ^
  [javac] ...\src\com\mirs\ecms\mdb\ECMSErrorHandlerMDB.java:25: illegal start of expression
  [javac] }
  [javac] ^
  [javac] 2 errors

The java class: ECMSDispatcherMDB.java

@MessageDriven( activationConfig = {
  @ActivationConfigProperty(propertyName = "destinationType",
                            propertyValue = "javax.jms.Queue"),
  @ActivationConfigProperty(propertyName = "destination",
                            propertyValue = Constants.CALLS_QUEUE_LOOKUP),
  @ActivationConfigProperty(propertyName = "maxSession",
                            propertyValue = "50"),
  @ActivationConfigProperty(propertyName = "transactionTimeout",
                            propertyValue = "30000"),
} )

public class ECMSDispatcherMDB implements MessageListener
{
    Logger logger = Logger.getLogger("ecms.log");
    private static final String TAG = "ECMSDispatcherMdb";
    ConnectorManager connectorManager = ConnectorManager.getInstance();

    @EJB
    private ECMSEntityManagerDaoLocal dao;
    ...

The java class: ECMSErrorHandlerMDB.java

@MessageDriven( activationConfig = {
  @ActivationConfigProperty(propertyName = "destinationType",
                            propertyValue = "javax.jms.Queue"),
  @ActivationConfigProperty(propertyName = "destination",
                            propertyValue = Constants.ERORR_QUEUE_LOOKUP),
  @ActivationConfigProperty(propertyName = "maxSession",
                            propertyValue = "50"),
} )

public class ECMSErrorHandlerMDB implements MessageListener
{
    Logger logger = Logger.getLogger("ecms.log");
    private static final String TAG = "ECMSErrorHandlerMDB";
    ConnectorManager connectorManager = ConnectorManager.getInstance();

    @EJB
    private ECMSEntityManagerDaoLocal dao;
    ...

And here's the Ant buildfile build.xml:

    </ear>

</project>

The errors are related to the Annotations I am using. What do I need to do to fix this Ant build to compile my class Annotations?

Answer 1

It looks like you have trailing commas in your annotation arrays, which javac views as illegal - unlike in 'proper' arrays. (There is a bug in eclipse that doesn't report these as such.)

Remove the trailing commas, e.g.:

@MessageDriven(activationConfig =
{ @ActivationConfigProperty( ... ),
  @ActivationConfigProperty( ... ),
  @ActivationConfigProperty( ... ),
  @ActivationConfigProperty( ... ) // no comma here
} );
