Hi One & All

I have a classfile called HelloWorldService with @WebServiceClient annotation. I want to use this classfile and need to be add one more annotation @HandlerChain using javaassist.

Code Snipped which I am working on.

When I am invoking the below code snipped I am getting only one annotation it is removing all the annotations and adding  the new one.

I am able to add annotation at runtime but it is adding only one annotation. But I want all the annotations? how to add multiple annotations?.

HelloWorldService.java

@WebServiceClient(name = "HelloWorldService")

public class HelloWorldService extends Service

{

}

Adding annotatins using javaassist

AddAnnotations.java

public byte[] makingAnnotationAtRuntime() throws Exception {

            ClassPool pool = ClassPool.getDefault();

            CtClass proxyClass = pool.get("HelloWorldService");

//get annotations from class called HelloWorldService

            Object[] all = proxyClass.getAnnotations();

            // get the class file and add the annotation

            ClassFile classFile = proxyClass.getClassFile();

            ConstPool constantPool = classFile.getConstPool();

            AnnotationsAttribute attr = new AnnotationsAttribute(constantPool,AnnotationsAttribute.visibleTag);

            Annotation annotation = new Annotation("javax.jws.HandlerChain", constantPool);

            annotation.addMemberValue("file", new StringMemberValue("HelloWorldService.xml",constantPool));

            attr.setAnnotation(annotation);

            proxyClass.getClassFile().addAttribute(attr);

            classFile.setVersionToJava5();

            // transform the classfile into bytecode

            ByteArrayOutputStream bos = new ByteArrayOutputStream();

            DataOutputStream os = new DataOutputStream(bos);

            classFile.write(os);

            os.close();

           //get annotations from Class

            all = proxyClass.getAnnotations();

            int i=0;

            for (Object object : all) {

                  System.out.println(all[i]);

                  i++;

            }

            return bos.toByteArray();

      }

When I run this I am getting the output : @javax.jws.HandlerChain(file="HelloWorldService_handler.xml")

But I want to get the other annotation as well. Original HelloWorldService Classfile contains @WebServiceClient(name = "HelloWorldService")

How can I get all annotations at run. Please suggest me I stuck to achieve this issue.

Please throw your thoughts.

Thanks in Advance
