Hi all, I am working on ejb3 project. Ejb3 always use some annotations such as "@Stateless","@Remote", "@RemoteBinding" and etc. Now I want to use javassist to generate these annotations. But have some problem. Can you help me to point out my mistake? <The class I wanna modify> | @Stateless | public class StatelessTest { | public String sayHello(String user) { | return "Hello" + user; | } | | } | <In this test case, I wanna put a new annotation "@RemoteBinding(jndiBinding = "StatelessTest /remote")" into StatelessTest class> | public class AnnotationTest extends TestCase { | public void testAnnotation() { | ClassPool pool = ClassPool.getDefault(); | pool.insertClassPath | ("D:/workspaces/.maven/repository/jboss/jars/jboss-annotations-ejb3-4.0.3.jar"); | CtClass c = pool.get | ("com.quartet.fwk.container.hivemind.qar.models.StatelessModel"); | ConstPool consts = c.getClassFile().getConstPool(); | ByteArrayOutputStream output = new ByteArrayOutputStream(); | AnnotationsWriter writer = new AnnotationsWriter(output, consts); | writer.numAnnotations(1); | writer.annotation("RemoteBinding", 1); | writer.memberValuePair("RemoteBinding"); | writer.constValueIndex("remote"); | writer.close(); | byte[] attribute_info = output.toByteArray(); | AnnotationsAttribute attribute=new AnnotationsAttribute(consts, | AnnotationsAttribute.invisibleTag, attribute_info); | c.getClassFile().addAttribute(attribute); | Object[] objs = c.getAnnotations(); | System.out.println(objs[1]); | I think these codes should work very well, but it throws exception: java.lang.reflect.InvocationTargetException detailMessage="bad descriptor: RemoteBinding"; thank for any replay!!
