Subject Re: ThirdParty Jars in GData
Date Thu, 09 Nov 2006 08:29:20 GMT
First it is / would be possible to just replace all the wireing
descriptors to spring configurations as the most ( all?!) of the IoC
DI containers use external descriptors. There is a central point ( the
servlet) where a single direct reference to hivemind will be hard
coded just to access the first reference to the hivemind managed
modules. Every servlet in the container is a subtype of an Basic
abstract servlet class which has a abstract method to obtain the first
reference. If you wanna switch to another IoC container the
replacement of the servlet in the web.xml file should be sufficient.
All the external jar / libs like the caucho WS impl. are also
integrated in Spring (not sure about pico but it won't be a problem).
So except of the meta data work people would have to do it is just a
replacement e.g reimplementation of a single method.

Instead of Registry.getService() it would be ApplicationContext.getBean()

is it that what you are alluding to?

Yesterday I checked out the ASF third party licensing policy...
The lists below declare which licenses are authorized and which
licenses are excluded from applying to any part of a product
distributed by an ASF PMC.
Authorized:
    * Apache License 2.0
    * ASL 1.1
    * BSD
    * MIT/X11
    * NCSA
    * W3C Software license
    * X.Net
    * zlib/libpng


Binary only:
    * CDDL 1.0
    * CPL 1.0
    * EPL 1.0
    * IPL 1.0
    * MPL 1.0 and MPL 1.1
    * SPL 1.0


So hivemind (requieres some other jars like javaassist it MPL and
apache oro is ASF) is ASF, Easymock is MIT, the caucho Hessian WS is
ASF.

So keep on downloading these libs for a build but it won't be a
problem to include these distributions inside a gdata distribution.

best regards Simon
