> In Geronimo, we always ship two saaj implementation, and in the past, we
> create wrapper implementations for those SPI, and configure them as system
> property. In the traditional service search strategy path, the configurations
> from system property have the highest priority. So we could control which
> implementation will be used After we switches to OSGi, a locator-registry
> solution is used for searching all the available service providers. For SAAJ
> provider, now we have two providers. and it seems that which one will be used
> is depending on which one is first registered in the global registry.
> I am thinking two solutions for this, and I prefer the option b.
> a. Introduce the priority feature for the service providers, the
> implementation could state its priority in the MANIFEST.MF file.
> b. Still take advantage of the system property, while the spec API
> requires the implementation, if the system property is configured and the
> implementation exists in the registry, use that one.
