Tim,
Lachlan,
Hi, this temporary code until bug#
225321 is fixed should in the case that you are running in eclipse - point to
the package-root classes directory that would contain the both the dynamic
persistence generation classes and the META-INF/persistence.xml - required
to define non-Entity configuration properties). If you are running your
persistence unit from a jar then it should be a url to that
jar.
"file:/C:/view_w34/examples/org.eclipse.persistence.example.jpa.dynamic/classes/"));
My
understanding so far of this example is that it generates an Entity
(DYNAMIC_EMP) at runtime in memory without a predefined @Entity class on
disk. An advantage of this would be that one could define the
attributes programmatically via XML - this closely follows the dynamic API
part of SDO (Service Data Objects) in our sdo subproject.
You may reference the corresponding Wiki page by the example author
at...
thank you

I've never done this, but from glancing at the bug report I
think you'd want to point it to the location of your classes directory
(the directory where your entity .class files are).
I'm not sure
if that's just your /classes or /bin or if you need to go down to the
package level.
Hi Tim,
I think it turns out that it is looking for the persistence.xml... not
100% as still get warnings?
here is the output of my first semi-successful test
so needless to say fairly happy...

So far i am liking Eclipselink....
i am however getting a warning when i run this test to both create the
entity and persist ?

Hi,
I have a question regarding dynamic entities
(which i think is awesome, and
helps answer an issue that has had me trolling the
net for the last few
weeks, and thus led me to Eclipselink, not to
mention increased performance
which i am also looking forward too).. I am just
trying to run some of the
example code however running into an issue with
:
// This root URL config should go away when bug
225321 is fixed
puInfo.setPersistenceUnitRootUrl(new
URL("file:/C:/Eclipse/EclipseLink/trunk/examples/org.eclipse.persistence.example.jpa.dynamic/classes/"));
I am just wondering what the url is meant to be
pointing at in particular?
any help would be great,
thanks,
-lachlan
