Please note there are 2 important APIs you should look at - JMX and
java preferences.
My view on configuration is that JMX should be used as the main
interface for the configurable components, and something similar
with java preferences ( but useable in JDK 1.4 ) for storing/reading
the data.

have seemingly their own boundaries Every little part is acting like its
own jakarta project. Hell, the votes are even working that way... This

Over time I have come to dislike checked exceptions. This is an example of
why. I now use unchecked exceptions when I can. So, to confuse you, both
solutions appeal and neither solution appeals. I thus remain skeptical
about
changing commons for transformation exceptions.
Until now, I have

limited class in todays terms:

- it doesn't support modern conventions

It is good idea. I think it is no need discuss a lot. Just paste this to

I took the liberty of adding jxpath to the list, because it also has an
introspection mechanism. IMO, it has way too much of it and breaking it out
would make tremendous sense.
When I was working on a product the current version of which is available
from Object Venture,
I don't know exactly how/if it fits in, but Ant does a fair bit
of introspection also. So far, I haven't been able to use beanutils
(I may be using it wrong) to do what Ant does.
Seems like most of the introspectors out there, given a name fileset
will look for something like addFileset(...),
Also check this with the ant team, who have a lot of introspection in
there code.. It works on all jdk versions afaik.
See o.a.tools.ant.Introspectionhelper.
+1 on the idea btw..

The problem is with the count. The tests have internal structure - sorry,
that might be bad idea, at least misleading.
The actual number of tests hiding behind the 8 you counted is about 350, you
need to count each XPath that is being tested, because they are designed to
provide very good
I think it must be a lot of code about this and it can be reused.
As does VelocityI think it calls it UberIntrospector or something.

The multitude of potential users of this component is huge, they all have

new component to be successful, we will need to address all of those
requirements, which calls for an abstract, configurable and customizable

There's some homework there! But it does show that the reflection API in
Java is proving to be too low level. Perfect for commons ;-)

Calling it reflect makes it analogous to java.lang.reflect. But, I
believe what we are after is something analogous to java.beans - that's
where the standard Introspector is.
How about introspection, org.apache.commons.introspection?

I want to nominate Stephen Colebourne as commiter on commons and sandbox,
He is one of the most active contributors with the great ideas and we know
his code.
I think we need to give him chance to do more for commons project.
We will need him in new project for reflection/introspection,
Actually I explicitly don't want to tie it to beans. Beans is a widely used
convention, but there are others
- EJBs are not really beans
- the naming convention surname() instead of getSurname() and
surname(String) instead of setSurname()
- classes that are auto generated from a 3rd party (non
I agree completely. I was not suggesting tying it to beans, just elevating
it over reflection, this is why I proposed introspection istead of
beans. But, I am not really opposed to reflect either.
