Has anyone used ServiceLoader together with Guice?

Question

I keep wanting to try this on a larger scale with our app + build system, but higher priorities keep pushing it to the back burner. It seems like a nice way to load Guice module

Answer 1

"because its impossible to bind the same interface twice."

This is indeed wrong! With Guice's Multibinder there is a way to work with different implementations of the same interface, possibly bound in different modules.

I came to a slightly different solution for the actual loading than Mark Renouf (his ModuleLoader looks indeed better), but my blog post may show a bit more about the environment where this approach is applicable (Plugins) and what the extension points look like:

Guice 2.0 Multibinder + Java ServiceLoader = Plugin mechanism
