changing the Jackrabbit embedded repository code
Is there an "easy" way for me to make modifications to the embedded
Jackrabbit repository that gets bundled with the standalone Sling?
I've built Sling from the latest code, and I've built a modified
version of Jackrabbit 2.1.1 (which is what it looked like Sling uses)
separately. I don't see where Sling gets its embedded Jackrabbit though.
All I'm trying to do is get a version of Jackrabbit into Sling where
the ObservationManager's Event.getIdentifer() method is functional via
RMI. Jackrabbit has currently left these unimplemented for RMI.
Thanks for any input on how to do this.

Excellent advice, particularly on the version naming. Though you made
it too easy, and I didn't need to read the Maven docs (but my
appreciation for Maven has increased somewhat). Thanks!
Now I just have to debug my RMI code.

You would be better off modifying the version to indicate that it's
patched. First, delete the patched version you installed in your local
Maven repository, then modify the jackrabbit-jcr-rmi POM file to have a
unique version (2.1.1-psu-1 would be my suggestion). Then re-run mvn
install.

Actually, Vidar got this second part wrong. As of 2.0,
jackrabbit-jcr-rmi is an OSGi bundle and, as such, is just included into
the Sling JAR/WAR. So the actual file to patch is
/launchpad/builder/src/main/bundles/list.xml
That said, you really would be well-served by learning a bit about
Maven. You don't need to be a master, but reading the first few chapters
of either
http://www.sonatype.com/books/mvnex-book/reference/public-book.html or
http://www.sonatype.com/books/mvnref-book/reference/public-book.html
would pay dividends.

Already did that, and have the jar. It also looks like what I built
was also installed in some kind of repository off my home directory
(hoping this is useful later):
.m2/repository/org/apache/jackrabbit/jackrabbit-jcr-rmi/2.1.1/
jackrabbit-jcr-rmi-2.1.1.jar

Right, but I know nothing about Maven and pom files, and it looks like
there is far more than one pom.xml file in the Sling source tree.
Seems like there are at least two references to "jackrabbit-jcr-rmi"
in pom.xml files:
bundles/jcr/jackrabbit-server/pom.xml
bundles/jcr/base/pom.xml
Both of which have:
<dependency>
<groupId>org.apache.jackrabbit</groupId>
<artifactId>jackrabbit-jcr-rmi</artifactId>
<version>2.0.0</version>
<scope>provided</scope>
</dependency>
If the change to the pom.xml file is "simple", care to explain that
part? Apparently I got the hard part.

I guess you will have to build your own version of
jackrabbit-jcr-rmi.jar (if that's what you need to get the method
exposed via RMI).
Then you would have to roll your own version of the bundle Sling
Jackrabbit Embedded Repository
(org.apache.sling.jcr.jackrabbit.server), where the only modification
you need is to include your jackrabbi-jcr-rmi.jar instead of the
standard one. A simple change in the pom.xml should be enough.
