Hi Frank,
Thanks for the update. FYI, these pages still mention the arrayAccessors option:
http://incubator.apache.org/tuscany/java_sdo_overview.html
http://cwiki.apache.org/TUSCANY/sdo-project-code-structure.html
There should be a warning to avoid this option. We have quite a bit of
code written already that uses this which will need to change. I'd
like to make sure other people don't fall into that scenario.
Thanks,
-Chris

Chris,
The -arrayAccessors option is just some prototype testing in Tuscany, it's
not supported. In fact, it's broken for several reasons these days. Since
we changed to the noEMF generator pattern (i.e., there should be no EMF
dependencies in the generated code), but notice that the getDog() method,
below, is generating code with EMF dependencies (BasicEList). We'll need
to fix that if we decide to keep this option.
Also note that the arrayAccessor pattern is not compliant with the SDO
specification, so for all of these reasons I would recommend not using it.
Frank.
