[forge-dev] [Roaster] Don't know how to add an annotation inside another one

Hi, This is a Roaster question. I've been trying to create a Bean Validation constraint properly... in vain. What I want to achieve is the following (notice the @List annotation) : @Target({*METHOD*, *FIELD*, *ANNOTATION_TYPE*, *CONSTRUCTOR*, *PARAMETER*}) @Retention(*RUNTIME*) @Documented @Constraint(validatedBy = {}) *public *@*interface *Email { String message() *default **"wrong email address"*; Class<?>[] groups() *default *{}; Class<? *extends *Payload>[] payload() *default *{}; @Target({*METHOD*, *FIELD*, *ANNOTATION_TYPE*, *CONSTRUCTOR*, *PARAMETER* }) @Retention(*RUNTIME*) @*interface **List* { Email[] value(); } } This is the code I've written. Both annotation are generated separately... but I don't know how to add listAnnotation inside emailAnnotation. Any idea ? Thanks public class Main { public static void main(String[] args) { // This is the inner annotation List final JavaAnnotationSource listAnnotation = Roaster.create(JavaAnnotationSource.class); listAnnotation.setName("List"); listAnnotation.addAnnotation(Retention.class).setEnumValue(RUNTIME); listAnnotation.addAnnotation(Target.class).setEnumValue(METHOD, FIELD, PARAMETER, TYPE); listAnnotation.addAnnotationElement("Email[] value()"); System.out.println(listAnnotation); // This is the annotation @Email final JavaAnnotationSource emailAnnotation = Roaster.create(JavaAnnotationSource.class); emailAnnotation.setPackage("org.agoncal.proj.constraints").setName("Email"); emailAnnotation.addImport(Payload.class); emailAnnotation.addAnnotation(Documented.class); emailAnnotation.addAnnotation(Retention.class).setEnumValue(RUNTIME); emailAnnotation.addAnnotation(Target.class).setEnumValue(METHOD, FIELD, PARAMETER, TYPE); emailAnnotation.addAnnotation(Constraint.class).setLiteralValue("validatedBy", "{}"); emailAnnotation.addAnnotationElement("String message() default \"wrong email address\""); emailAnnotation.addAnnotationElement("Class<?>[] groups() default {}"); emailAnnotation.addAnnotationElement("Class<? extends Payload>[] payload() default {}"); // I was expecting to have a method like that so I could add annotation inside another one // emailAnnotation.addAnnotationElement(emailAnnotation); System.out.println(emailAnnotation); } } -- Antonio Goncalves Software architect and Java Champion Web site <http://www.antoniogoncalves.org/> | Twitter<http://twitter.com/agoncal> | LinkedIn <http://www.linkedin.com/in/agoncal> | Paris JUG<http://www.parisjug.org/> | Devoxx France <http://www.devoxx.fr/>
