Question

I’m trying to use the @Catch annotation to catch any JAXB UnmarshalExceptions generated in my application. I tried using the code described in the Play Documentation for @Catch:

    @Catch(UnmarshalException.class)
    public static void addUnmarshalError()  {...}

and

    @Catch(value = UnmarshalException.class, priority = 1)
    public static void addUnmarshalError()  {...}

but neither works.

Each time I use the annotation I get the message:

Oops: IllegalArgumentException
An unexpected error occured caused by exception IllegalArgumentException: wrong number of arguments

I don’t think it’s the code inside the method, since even an empty method body generates the exception. Is there something I’m missing in my @Catch call?

Answer 1

Your method should take a throwable as a parameter:

@Catch(UnmarshalException.class)
    public static void addUnmarshalError(Throwable throwable)  {...}
