What is the best way of searching the whole classpath for an annotated class?
I'm doing a library and I want to allow the users to annotate their classes, so when the Web application starts I need to scan the whole classpath for certain annotation.
Do you know a library or a Java facility to do this?
Edit: I'm thinking about something like the new functionality for Java EE 5 Web Services or EJB's. You annotate your class with
A component provider that scans the classpath from a base package. It then applies exclude and include filters to the resulting classes to find candidates.
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(<DO_YOU_WANT_TO_USE_DEFALT_FILTER>); scanner.addIncludeFilter(new AnnotationTypeFilter(<TYPE_YOUR_ANNOTATION_HERE>.class)); for (BeanDefinition bd : scanner.findCandidateComponents(<TYPE_YOUR_BASE_PACKAGE_HERE>)) System.out.println(bd.getBeanClassName());
