Re: [Geotools-gt2-users] geotools library as an OSGI plugin

[whatnick <ti...@el...>]

There are 2 possibilities for dealing with the SPI based services issue:

1) Interceptor pattern at runtime to look at services definitions and
generate OSGi services when a bit of text is detected - as done by the JBoss
interceptor
(http://docs.jboss.org/osgi/userguide/html_single/#SecServiceLoader). I
believe such an interceptor does not need to be part of geotools per-se, but
part of the OSGi runtime the ServiceLoader based jar's are deployed under.
This point outlines my modifications to Mathieu's option 1.

2) The declarative services and compile time rejigging of META-INF/services
to OSGI-INF/*.xml - The only sore point for me here is how we are  going to
do the compile time hackery. The osgi maven plugins don't really cover this.
May be it is time to get the Bnd author (Peter Krien's) wisdom on this
matter.

I have a preference for option 1 but I would rather do the
LifecycleInterceptor outside of Geotools. Thanks for the offer to prototype
Mathieu, putting code where your mouth is.

Cheers,

Tisham.
