Hi!

Is it possible to find classes that are annotated with specific annotation?

I'm writing an application and I'd like to create very simple mechanism
that would allow me to use plugins. I would like to have a name for each
plugin and I would like to be able to find a class given this name (and
not the class name...). For example, I have an annotation like this:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface Plugin {

    String value();
   
}

and somewhere in the classpath there is a class TestTask:

@Plugin("testTask")
public class TestTask extends BaseTask {

    static final Logger logger = Logger.getLogger(TestTask.class);

    public void execute() throws TaskExecutionException {
        logger.info("message from a plugin");
    }
}

I'd like to be able to find class TestTask given the string testTask so
I could instantiate it and run whatever it does (in this case print
message to Log4J). How to do this?

Best Regards,
