Thanks for your help. I solved the problem. After I fixed a version mismatch in SLF4J Bean Validation was enabled. Maybe the initialization checks the logger?

First, did you package the myfaces jars in the application or in a shared library or something? And the same question for the validation api and impl jars And this Class.forName check is not the complete check. After Class.forName, we completely initialize the bean validation framework, using the default factory. If this fails, I decided to disable bean validation. But in this case, you should see more logging. For example the error message, explaining why the beanval initialization failed. You can set the logger for "javax.faces.validator" to "fine" to see the error message, if any. Otherwise, putting a breakpoint in the javax.faces.validator.BeanValidator.createValidatorFactory() method and stepping into _ExternalSpecifications.isBeanValidationAvailable() would also be a very good first step. @Committers: I decided to log it as fine a year ago, because I can't decide whether or not the exception is important. I didn't want to irritate and scare developers when there is no issue. But we might be better off logging it as info, for cases like this one. Or maybe a second catch clause for specific bean validation exceptions that logs its messages as info. But then again, not every exception thrown by the buildDefaultValidatorFactory has to be that type. For example, NoClassDefFoundErrors could also occur. What do you think?
