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

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
