Rick Hillegas commented on DERBY-3983:
--------------------------------------
Hey Knut, thanks for the quick feedback!
1) It is true that elsewhere the user guides say that you need Xalan in order
to use the XML datatype. And if you know that those libraries aren't included
in CDC/FP 1.1, then you can deduce that the XML datatype is not supported on
small devices. However, the point of this JIRA is to collect together all of
the known limitations of our small device support so that users can figure out
at a glance what's supported and what's not.
2) It's true that we don't say anything about non-blocking io elsewhere in our
user guides. I don't know whether that's good or bad. However, I think that
it's worth pointing out that the small device implementation is different here.
6) I agree with this improvement. We should state that in general,
client/server features are not available on small devices. This includes
SSL/TLS support and Replication.
Thanks!

> Project: Derby
> Issue Type: Improvement
> Components: Documentation
> Affects Versions: 10.5.0.0
> Reporter: Rick Hillegas
>
> The limitations of Derby's feature set on small devices is sketched in the
> Reference Guide in a section titled "JDBC Package for Connected Device
> Configuration/Foundation Profile (JSR169)". This section should be expanded
> to include other unsupported features identified in DERBY-3966:
> 1) Lack of XML datatype (can be remedied if the small device platform can be
> supplemented with some extra, freely available jar files)
> 2) Non-blocking io
> 3) Java EE resource manager support, including distributed transactions
> 4) Principal-based security
> 5) LDAP-based authentication
> 6) SSL/TLS encryption
> 7) Replication
