Problem using BeanValidator

Vaadin 6 / 7 / 8 Framework UI
1

Hello everyone.
I don’t know if this is the right forum (in case, I apologize) but I’m getting crazy about an error launching CRUD example in ECLIPSE and in Tomcat 9.0.
The error throws when i click on the Login button: it getes “A JSR-303 bean validation implementation not found on the classpath or could not be initialized. BeanValidator cannot be used.”
In \WEB-INF\lib\ there are both “hibernate-validator-5.1.0.CR1.jar” and “validation-api-1.1.0.Final”.
Maybe is a stupid thing, but this issue is giving me an headache.

Thanks in advance

Hi Samuele,
nothing relevant other than the message in the log file? Can you post the stacktrace?

Debugging test application, I’ve seen that the error thrown when BeanUtilClass try to find “javax.validation.Validation” class.

    private static class LazyValidationAvailability implements Serializable {
        private static final boolean BEAN_VALIDATION_AVAILABLE = isAvailable();

        private static boolean isAvailable() {
            try {
                Class<?> clazz = Class.forName("javax.validation.Validation");
                Method method = clazz.getMethod("buildDefaultValidatorFactory");
                method.invoke(null);
                return true;
            } catch (ClassNotFoundException | NoSuchMethodException
                    | InvocationTargetException e) {
                Logger.getLogger(BeanValidator.class.getName()).log(Level.INFO,
                        "A JSR-303 bean validation implementation not found on the classpath or could not be initialized. "
                                + BeanValidator.class.getSimpleName()
                                + " cannot be used.",
                        e);
                return false;
            } catch (IllegalAccessException | IllegalArgumentException e) {
                throw new RuntimeException(
                        "Unable to invoke javax.validation.Validation.buildDefaultValidatorFactory()",
                        e);
            }
        }

Thats qll.

Here is the cause of the exception

Caused by: java.lang.NoClassDefFoundError: org/apache/geronimo/osgi/locator/ProviderLocator at javax.validation.Validation$DefaultValidationProviderResolver.getValidationProviders(Validation.java:209)

I don’t use eclipse so I don’t know if the problem is related to the IDE.
Have you tried to deploy the war on an external tomcat?

Maybe if you add a dependency to org.apache.geronimo.specs:geronimo-osgi-locator it will work, but this will be just a workaround

This just happened to me and I was missing this dependency.

<!-- Bean validation implementation-->
<dependency>
	<groupId>org.hibernate.validator</groupId>
	<artifactId>hibernate-validator</artifactId>
