I was thinking along the lines Michael says. e.g.: public interface DefaultValidationConfigurationProvider { InputStream getDefaultValidationConfiguration(); }
Then we use ServiceLoader (functional equivalent for BVal 1.0, Java 5) to find any available implementations. If none found, we fall back to: class StandardDefaultValidationConfigurationProvider implements DefaultValidationConfigurationProvider { final Properties properties; StandardDefaultValidationConfigurationProvider(Properties properties) { this.properties = properties; } public InputStream getDefaultValidationConfiguration() { // look for property pointing to custom resource, else META-INF/validation.xml // ensure only one such resource // return getResourceAsStream(resourceName) } } This way TomEE would simply have to provide: WebApplicationDefaultValidationConfigurationProvider implements DefaultValidationConfigurationProvider { public InputStream getDefaultValidationConfiguration() { return getServletContext().getResourceAsStream("WEB-INF/validation.xml"); } private static ServletContext getServletContext() { // TBD } } Matt On Wed, Mar 19, 2014 at 10:28 AM, Romain Manni-Bucau <rmannibu...@gmail.com> wrote: > Actually I'd expect the SPI to give the processed instance and not the > location.
