Rick Hillegas commented on DERBY-5955:
--------------------------------------
Thanks, Dag. The javadoc is very helpful. This is my understanding of how an
application would use these DataSources:
1) If the application wants to run with JNDI, then the application would use
the same DataSources which are used in 10.9.
2) If the application wants to run on the small CP2 profile, then the
application would use the corresponding NonJNDI* DataSources instead.
It would probably be useful to touch up the header javadoc for all of the
DataSources in order to make it clear which environment they should be used in.
Thanks!

> While waiting for a Java module system (aka project Jigsaw), it has been
> decided to define a few subsets of the Java SE Platform Specification, cf JEP
> 161 ( http://openjdk.java.net/jeps/161).
> A quote from the JEP: "More broadly, this feature is intended to enable the
> migration of applications currently built on top of the Java ME Connected
> Device Configuration (CDC) to appropriate Profiles of the Java SE Platform,
> part of the long-term effort to converge CDC with Java SE."
> It would be good if we make Derby to run on such limited profiles. The
> current proposal places JDBC in Compact Profile 2 (cf. link above), while
> other libraries used by Derby, e.g. javax.naming (JNDI) are in Profile 3
> (larger).
> It would be good if Derby could run on the smallest posible platform, i.e.
> Profile 2, but that will probably involve some changes to make Derby
> gracefully limit functionality when some libraries are missing.
