从jar文件扫描注释

Question

Is it possible to scan annotations (Ex: javax.ejb.MessageDriven) from an external jar project.

I need to extract information from a given ear file . It is possible to do with EJB 2.x by parsing the deployment descriptors (ejb-jar.xml) but not quite for EJB 3.x

If possible, please give me an example.

Thank you very much for any reply.

Thanks, rlegendi

Look like Scannotation is a find solution for me. Here is the example:

URL[] urls = { new URL("jar:file:" + pathToJar+"!/") };
AnnotationDB db = new AnnotationDB(); 
db.scanArchives(urls);
System.out.println(db.getAnnotationIndex().get(javax.ejb.MessageDriven.class.getName()));
