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!!
