Bean validation with hibernate in karaf, cxf and dosgi - osgi

Question

I have jax-rs services exposed in Karaf with cxf dosgi. I am trying to add bean validation with a hibernate provider.
I Installed the hibernate-validator feature
I Installed the cxf-bean-validation and cxf-bean-validation-core features although I am not sure whether they are both needed.
I added the following intent to enable the hibernate provider:
#Component(immediate = true, property = "org.apache.cxf.dosgi.IntentName=bean-validation")
public class BeanValidationIntent implements Callable<List<Object>> {
#Override
public List<Object> call() throws Exception {
List<Object> list = new ArrayList<Object>();
BeanValidationFeature beanValidationFeature = new BeanValidationFeature();
beanValidationFeature.setProvider(new BeanValidationProvider(new HibernateValidationProviderResolver()));
list.add(beanValidationFeature);
return list;
}
}
But I am getting the exception in the bottom. I added the bundle (wrapped) which contains the missing class:
install -s wrap:mvn:com.sun.el/el-ri/1.0
This still doesn't solve the problem.
I am using karaf 4.0.8
Please share if you have any idea! Thanks!!

Answer 1

The EL ExpressionFactory initialization is a bit buggy: it uses the TCCL instead of using its own class loader and our Karaf feature does not import com.sun.el as it shouldn't be necessary.
We introduced the externalClassLoader() method in HV to (among other things) work around this issue.
See how we do use it in our OSGi integration tests:
https://github.com/hibernate/hibernate-validator/blob/5.4/osgi/integrationtest/src/test/java/org/hibernate/validator/osgi/integrationtest/OsgiIntegrationTest.java#L139
(Note that in 5.4, you also need the providerResolver() call - this limitation is removed in the soon to be coming 6.0)
