IoC services - can they come from an external jar?
Hi Tapestry Users,
It gives me great pleasure to have a question to ask this list after picking
up some tapestry deving again.
I'm playing around with a new EJB3.1 book with icedtea6 (openjdk) running on
glassfishv3.1.1.
Using jumpstart's BusinessServicesLocator(BSL) and bind() -ing it in
AppModule.java I wondered if the BSL and it's interface can come from
another jar or does it have to be in the services directory?
Thanks for your time,
Chris
P.S. how is the tapestry 5 in action book going? i read chapter 1 about 3
or 4 months ago i think and it was an amazing explanation of a terrific
framework! Thanks everyone :D

My "No" is a bit ambigous ;-)) So: No they don't have to be in the same
jar/Yes, they can come from an external jar

To nillehammer and Thiago, thank you for answering.
Eclipse on gentoo is acting a little weird in not being able to find classes in the same project, so I thought I'd make BSL a separate jar to ease my woes :)
Trying to move away from osx to gentoo for deving on. (don't ask why, i enjoy the painful freedom!)

Granted. And how that works is, what I was trying to explain in my first
reply to the question. I wanted to point out, that this feature goes far
beyond just having services in a different jar. Admiddetly my explanation
was a bit too clumsy or short.

Well, my definition of distributed configuration is different: it's the
ability of more than one module class to contribute configuration for a
given service. Spring and Tapestry-IoC have the ability of having
different sources of configuration (modules) and packing them in different
JARs, but only Tapestry-IoC has distributed configuration.
From http://tapestry.apache.org/tapestry-ioc-configuration.html: "One of
the key concepts in Tapestry IoC is distributed configuration. The
distributed part refers to the fact that any module may configure a
service. Distributed configuration is the key feature of Tapestry IoC that
supports extensibility and modularity."

No, that's part of what Tapestry calls "distributed configuration" You can
define separate modules and pack them into separate jars. If you want them
used in your AppModule yo can do this in two ways:
Either use the @SubModule-annotation telling AppModule, what the other
module's class name is. Or pack a MANIFEST.MF with apropriate entry with
your jar. Tapestry will scan for that and find your module. Here you'll find
more detailed info:

Tapestry-IoC doesn't care at all about what package or JAR you put your
services.
