initializing EMF with lists of mapping files
Hi List,
I am running JPA with a set of mapping files, one for each table in the database
plus a few for queries, and in my test environment I have additional mapping
files that aren't required in container and in fact I would like to exclude.
So I made a second test persistence.xml and now I find though that I have to
maintain 2 lists of mapping files.
I would like to initialize the entity manager factory programmatically to add
the main list of mapping files, and then in testing, to add the extra mapping
files as well.
There seems to be no method on the API where I do that programmatically though.
Is that correct or have I overlooked something?
Regards
Adam

OK, I hadn't thought of an XML technique for this.
Regarding the EntityManagerFactory.createEntityManager(String puName, Map props)
call, are you saying that I can pass in the mapping file names as map entries
with the key 'mapping'?
I hadn't thought of trying that even since the <mapping> node in persistence.xml
is not a child of the <properties> node.
Regards
Adam

I would expect it to work with any (validating) XML parser. XSDs are
internal to the XML language; entities are external insofar as they're
SGML markup that the XML parser obeys.
That said, I could be totally wrong; maybe XSD-validating parsers
ignore DTD and entity content.
Ignoring your editor, what happens if you put an <!ENTITY declaration
after the <?xml bit but before the <persistence bit?

Is that for use with DTDs only? It's not recognised by my XML editor where my
persistence.xml starts:
<?xml version="1.0" encoding="UTF-8"?>

Re: initializing EMF with lists of mapping files

Hi,
Probably the best way to do that is with XML entities:
<!ENTITY commonmappings SYSTEM "commonmappings.xml">
<persistence-units>
<persistence-unit name="pu1">
&commonmappings;
<mapping-file>pu1-mappings.xml</mapping-file>
</persistence-unit>
<persistence-unit name="pu2">
&commonmappings;
<mapping-file>pu2-mappings.xml</mapping-file>
</persistence-unit>
</persistence-units>

I omitted to mention that the pseudo-XML I gave doesn't work and I'm not clear
how I can get it to include the other file.

I have 2 persistence units, which share many of their mapping files, so it is
more like this:
<persistence-unit name="mypu">
<mapping-file>mypu.xml</mapping-file>
<mapping-file>orm1.xml</mapping-file>
<mapping-file>orm2.xml</mapping-file>
</persistence-unit>
<persistence-unit name="other">
<mapping-file>other.xml</mapping-file>
<mapping-file>orm1.xml</mapping-file>
<mapping-file>orm2.xml</mapping-file>
</persistence-unit>
and I want to cut out the duplication of the shared mapping files by including
just 1 seperate xml snippet like this:
<persistence-unit name="mypu">
<mapping-file>mypu.xml</mapping-file>
<xi:include href="shared-mapping.xml"/>
</persistence-unit>
<persistence-unit name="other">
<mapping-file>other.xml</mapping-file>

Hi Adam,
Something like this should work :
<persistence-unit name="mypu">
<mapping-file>orm1.xml</mapping-file>
<mapping-file>orm2.xml</mapping-file>
. . .
</persistence-unit>
Is this what you're looking for?

Re: initializing EMF with lists of mapping files

I'm getting nowhere trying to massage my persistence.xml into something that
validates and at this point I'm getting spurious errors from Eclipse about the
well-formedness of the XML, so I'll ask here to see if anyone's got an example
to hand.
I would like to include a list of mapping files in multiple places in my
persistence.xml (once in each persistence unit). I tried several different ideas
from the web, but I haven't got anything to validate in my XML editor yet.
i.e. I have a list like this:
<mapping-file>org/permacode/patternrepo/orm/Category.xml</mapping-file>
<mapping-file>org/permacode/patternrepo/orm/Market.xml</mapping-file>
<mapping-file>org/permacode/patternrepo/orm/Code.xml</mapping-file>
<mapping-file>org/permacode/patternrepo/orm/TestResult.xml</mapping-file>
<mapping-file>org/permacode/patternrepo/orm/TradingParam.xml</mapping-file>
which I want to include - I'd be really grateful if someone could tell me the
xml syntax for the include?
Thanks

This is something I've been trying to sort out for a while -
every now and then it catches me out and I waste time tracking
down my error to the omission of a new entity mapping file from
one of the persistence units in my persistence.xml.
Below, it's suggested that I can feed JPA the list of mapping files
via the EntityManagerFactory.createEntityManager() method. I tried
this out with no success. I doesn't seem possible, surely?
The alternative is to use XML entities - has anybody done this with
success?
Thanks

Hi,
You can do this with the
EntityManagerFactory.createEntityManager(String puName, Map props)
signature.
Alternately, you can use XML entities to define the shared mappings
outside of your persistence units and refer to them in multiple
places.
