It looks like a factory for a validation service might be looking for
the declaration of
the validation service.
These are often declared in a file in META-INF/services in
jars that are the providers of that service so take a look at the jars
in your
web apps lib directory. That same declaration can be made
programmatically using
System.setProperty("javax.validation.spi.ValidationProvider",
packagename.validatationclass)
if you know what it is and do not want to alter the jar file.
