[jboss-user] [JBoss AOP] - Please help with reflection

[bornmw]

Hi!

I have a very stupid problem with reflection.

My exception is:

  | java -cp .:/projects/lib/jboss-aop_1.5.5.GA/lib-50/jboss-aop-jdk50.jar:/usr/local/pluto-1.1.4/shared/lib/portlet-api-1.0.jar:/usr/local/pluto-1.1.4/webapps/AOPPortlet/WEB-INF/lib/concurrent.jar:/usr/local/pluto-1.1.4/webapps/AOPPortlet/WEB-INF/lib/javassist-snapshot.jar:/usr/local/pluto-1.1.4/webapps/AOPPortlet/WEB-INF/lib/jboss-common.jar:/usr/local/pluto-1.1.4/webapps/AOPPortlet/WEB-INF/lib/trove.jar ConstrTest

  | 
  | 

My code is:

  | ClassLoader loader = Thread.currentThread().getContextClassLoader();
  | Class clazz = loader.loadClass("Test");
  | for (int j = 0; j < clazz.getConstructors().length; j++) {
  | 	Constructor constructor = clazz.getConstructors()[j];
  | 	System.out.println("constructor = " + constructor);
  | }
  | Test t = (Test) clazz.newInstance();
  | System.out.println("t = " + t);
  | 

Test is a class that is aspectized at compile-time.
What am I doing wrong? Or is it not possible to construct aspectized classes using reflection at all?

Thanks
