Schema target name space
The schema target namespace seems to be http://java.sun.com/xml/ns/j2ee.
Shouldn't it be http://geronimo.apache.org/xml/schema/j2ee?

Another issue that I just noticed is that we have copied Sun's web
Schema into the Geronimo Web schema (see geronimo-web-app.xsd) including
the Sun copyright and the part saying you can't reproduce it without prior
written consent from Sun. I suspect we ought to remove this and replace
it with something more like the geronimo-ejb-jar.xsd

I think we need to discuss this. I originally thought to use the
http://geronimo.apache.org/xml/schema/j2ee address. But I've been burned
by the changing DTDs of "certain other products" enough that I then
decided it should be something more like
http://geronimo.apache.org/xml/schema/1.0/j2ee/1.4/ where the first
version is the product version and the second version is the J2EE version
or something, since we'll need to support several J2EE versions in each
Geronimo version (though of course only one of them uses schemas so far).
But I think many of the Geronimo schemas were changed to use the
Sun namespace so they would all appear in one pool with the Sun tags.
That is, you could use:
<entity>
<ejb-name>foo</ejb-name>
<jndi-name>bar</jndi-name>
</entity>
Where you mix the Sun "entity" and "ejb-name" tags with the
Geronimo "jndi-name" tag without needding to use namespaces:
<entity>
<ejb-name>foo</ejb-name>
<ger:jndi-name>bar</ger:jndi-name>
</entity>
Of course, that's a bad example because Sun defines a "jndi-name"
element, but you get the idea.
On the other hand, we haven't done a very complete job, since now
there's *both* a Sun "jndi-name" and a Geronimo "jndi-name", and you have
to use one for the EJBs and the other for resolving references, which is
the worst of both worlds, because you don't know which you're supposed to
use until your validating parser barfs. I think that could be fixed by
changing the namespace declaration in geronimo-common.xsd.
Anyway, my preference would be to declare all the Geronimo tags in
a Geronimo namespace. If every app server decided to put its custom tags
in the J2EE namespace, there could be some fairly unpleasant collisions.
I'm not yet decided whether we should repeat all the base Sun tags in a
big set of copy schemas (ick), or force the use of namespaces within the
Geronimo DD (ick). I guess my real preference is to split the DDs back up
again so that's not a problem. :)
