JPA and ORM.XML not detected

[rbadert]

My ORM file is contained in a separate jar file where all the business logic is stored. This package is imported as a library into my web project. Apparently it is not detected during startup as my named queries are not available.
In a persistence.xml file i have the property "mapping-file" to specify my ORM file.

I patched the JPAPlugin.java with the following code:

/** Support ORM file, rb 24.05.2010 */
String mappingFile = Play.configuration.getProperty("jpa.mapping-file", "");
if (mappingFile != null && mappingFile.length()>0) {
  cfg.addResource(mappingFile);
}

and add the following entry into "application.conf":
jpa.mapping-file=META-INF/orm.xml

then my orm.xml file will be detected by Hibernate.

Thanks, if I remember correctly orm.xml is the default name and you should not need it to specify it, correct? I will have a look at the JPA spec in any case.

Yeah that's correct - but you could give it another name and then you have to name it in the persistence.xml.
I added this, as Hibernate didn't recognize it in my Play application; probably because it is contained in a separate jar file which contains all the business logic. I even had to define jpa.entities=...., .... in the application.conf file to trigger the JPA entity manager. Looks like Play looks only into the model directory.
