Many thanks for confirming that, Andy.

JDO standard metadata mechanism is as you describe, see

http://www.datanucleus.org/products/accessplatform_5_0/jdo/metadata.html

which gives order or priority of the different metadata input types. The 
merging process is not perfect but tries to handle all common situations.

Re: Redefining schema name in config file (to override JDO class annotation setting)

Hi Steve (and Oscar)

Just been playing around with this using the simpleapp.

What I've found is that by adding a file SimpleObject.jdo (in the
domainapp/dom/simple package, right alongside SimpleObject.java), with the
contents:



http://xmlns.jcp.org/xml/ns/jdo/jdo";
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/jdo/jdo
http://xmlns.jcp.org/xml/ns/jdo/jdo_3_0.xsd";>







then this was enough to change the schema.  (If you try to repeat this
test, note that the SimpleObjectTeardown fixture also needs to be changed
to reference the different schema).

When I went to download the JDO metadata before-and-after the change (on
the metadata panel), the only difference is this change in schema.

So, it looks like DataNucleus will merge any XML metadata with any
annotations (with the XML metadata taking preference).  In other words,
exactly what we want.  (Andy, if you pick this up, any
comments/corrections?)

Let me know if this works for you, too.

Thanks.
Dan

Hi Stephen,

Found Dan’s comment on a issue on github which details how to override it with 
“package.jdo” in META-INF:

https://github.com/isisaddons/isis-module-security/issues/35


HTH,

Oscar

Redefining schema name in config file (to override JDO class annotation setting)

[Stephen Cameron]

Hi,

I am using the security module which defines a schema 'isissecurity', but
in MySQL the security tables get created in the default schema. Everything
works fine, but I still get an error message at startup which I'd like to
get rid of.

I'm pretty sure I've seen reference to a means to remap the schema name via
a Datanucleus configuration (persistence.xml?), if someone could show me
how this is done, or point me to relevant documentation that would be
appreciated.

Thanks
Steve Cameron
