I would like to know if there is a possibility how to solve problem when I have my own library that uses hibernate validator and it is running in standard and also OSGI environment. It means the same library is used in OSGI-based server and also for client which isn't OSGI-based. For standard environment everything works fine but for OSGI I have got exception :

javax.validation.ValidationException: Unable to find a default provider
at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:264)

There are instructions what to do for OSGI (ValidationProviderResolver), so I assume it will work. But will it work also in standard environment?

Hi,

I am not an OSGI expert, but would your library not include the required OSGI metadata in its manifest. In particular the dependency to Bean Validation?

Hi,

the general problem here is that the standard approach defined by the BV spec for finding BV providers - which utilizes Java's service loader mechanism - per definition does not work in OSGi environments.

This is because in OSGi the BV bundle can't see any service provider configuration files provided by implementation bundles in META-INF/services. As mentioned in the spec (section 4.4.4.1) the idea here would be to implement a custom ValidationProviderResolver which leverages for instance OSGi declarative services to make BV implementations known to the BV bootstrapping. So you would work with this custom resolver within an OSGi environment and with the default resolver provided by BV within in a standard environment with one common class path.
