Now, JSR-170 does *not* specify how a Repository should be obtained. This
probably means that to abstract implementation-dependent initialization of
repos, you probably have to come up with an abstraction for this. One
possibility is to come up with an interface like RepoFactory and load the
implementation by getting the actual classname from web.xml.
well, it seems to me that it would make sense that JCR itself would
provide such an interface, just as jdbc is providing a DatabaseDriver.
The JCR does not but the container infrastructure does; I posted about this on
jackrabbit-dev and it seems that indeed JNDI is the way to go;
right, but I guess the binding then needs to be configurable
within the container, right? And we basically have to
provide different bindings related to the various implementations, e.g.
Jackrabbit, Jeceira, etc. ...
additionally,
implementation-related dependencies can be avoided and there should be no
need for implementation dependent initializers.
Instead, along with JNDI, the app descriptor will have to declare the repo as
a resource like:
<resource-env-ref>
<description>Content Repository</description>
<resource-env-ref-name>jcr/repository</resource-env-ref-name>
<resource-env-ref-type>javax.jcr.Repository</resource-env-ref-type>
</resource-env-ref>
and use the value of resource-env-ref-name to obtain the repo from JNDI. If
you guys give me a go,
I don't think there is any reason to wait ;-) please go :-)

Tomcat.
