Using 4.2.0CR2. I am using TestNG from within a Stateless Session Bean. The TestNG jar for jdk1.5 is in the ear/lib directory, and I can import the main TestNG class just fine, so I know it is actually on the classpath. TestNG uses reflection internally to load and instantiate some TestRunners, etc. I get: java.lang.NoSuchMethodException: org.testng.internal.annotations.JDK15AnnotationFinder.<init>(org.testng.internal.annotations.IAnnotationTransformer) | java.lang.Class.getConstructor0(Class.java:2647) | java.lang.Class.getConstructor(Class.java:1629) | org.testng.internal.ClassHelper.createJdkAnnotationFinder(ClassHelper.java:175) | org.testng.TestNG.initializeAnnotationFinders(TestNG.java:692) | org.testng.TestNG.run(TestNG.java:701) | The relevant section of ClassHelper.java is: | try { | Class clazz= forName(JDK5_ANNOTATIONFINDER_CLASS); | Constructor ctor= clazz.getConstructor(new Class[] {IAnnotationTransformer.class});//Exception here | return (IAnnotationFinder) ctor.newInstance(new Object[] {annoTransformer}); | } | catch(Exception ex) { | throw new TestNGException("Cannot create/initialize the JDK5 annotation finder " + JDK5_ANNOTATIONFINDER_CLASS, ex); | } | Please note that I added the comment showing which line throws the exception (line 175) It works fine when called from the web context if the jar is in WEB-INF/lib, but that doesn't meet our needs. According to http://jira.jboss.com/jira/browse/JBAS-4037 the lib directory within an ear should work as defined in the EE5 spec - Does that not include reflection? (Or is this a bug?) Thanks in advance for any help you can supply. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4041998#...
