I've started using openEJB in conjunction with hibernate and derby to run
unit tests from within Eclipse. I've been trying to use the
openejb.altdd.prefix property to specify an alternate persistence.xml file
with the derby db drivers and some additional paramters, but it doesn't seem
to be getting picked up.
I'm also using the @LocalClient annotation on my tests to inject the session
beans that I am testing.
I've got multiple modules in my class path that are being scanned, and they
look something like this:
jpa/classes/com... // entity beans
jpa/classes/META-INF/persistence.xml // not the one I want to use for unit
tests
jpa/classes/META-INF/test.persistence.xml // this is the one I want to use
ejb/classes/com... // session bean classes
ejb/classes/META-INF/ejb-jar.xml
test/classes/com... //unit tests annotated with @LocalClient
test/classes/META-INF/application-client.xml // this file just has the root
node so that openejb will scan this directory for @LocalClient
All my unit tests have this method:
@Before
public void initializeInjection() throws NamingException {
Properties p = new Properties();
p.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");
p.setProperty("openejb.altdd.prefix", "test");
InitialContext initialContext = new InitialContext(p);
initialContext = new InitialContext(p);
initialContext.bind("inject", this);
}
When I step through the unit tests, I get to the initialContext = new
InitialContext(p) line and it seems to load persistence.xml and not
test.persistence.xml. I can tell this because of this line in the log:
INFO: Using dialect: org.hibernate.dialect.Oracle10gDialect
and because all my tests fail saying that the tables do not exist (since
test.persistence.xml has <property name="hibernate.hbm2ddl.auto"
value="create-drop" /> but persistence.xml does not).
If I remove persistence.xml and just keep test.persistence.xml, I get errors
like this complaining about the ejb/classes and the test/classes:
ERROR - FAIL ... UserFinderFacade: A persistence unit must be defined via
META-INF/persistence.xml to satisfy @PersistenceContext ref "em" to unit
"PromoPersistence". An example of a suitable persistence.xml might
be:<persistence xmlns="http://java.sun.com/xml/ns/persistence";
version="1.0"><persistence-unit
name="PromoPersistence"><jta-data-source>java:openejb/Resource/myDataSource</jta-data-source><non-jta-data-source>java:openejb/Resource/myUnmanagedDataSource</non-jta-data-source><properties><property
name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema(ForeignKeys=true)"/></properties></persistence-unit></persistence>
ERROR - Invalid
EjbModule(path=C:\workfolder\promo.service\build\ejb\classes)
If I copy test.persistence.xml into all 3 META-INF directories, then it
picks up the test.persistence.xml in the other folders and puts this in the
logs:
INFO - AltDD persistence.xml ->
file:/C:/workfolder/myproj/build/ejb/classes/META-INF/test.persistence.xml
INFO - AltDD persistence.xml ->
file:/C:/workfolder/myproj/build/ejb/classes/META-INF/test.persistence.xml
INFO - Beginning load: C:\workfolder\myproj\build\test\classes
INFO - AltDD persistence.xml ->
file:/C:/workfolder/myproj/build/test/classes/META-INF/test.persistence.xml
INFO - Beginning load: C:\workfolder\promo.service\build\jpa\classes
but not the one in the jpa directory, and I still get the "A persistence
unit must be defined via META-INF/persistence.xml" for the ejb and test
jars.
If I throw a test.ejb-jar.xml into classes/jpa/META-INF then my
test.persistence.xml does get picked up, and I see this in the logs:
INFO - AltDD persistence.xml ->
file:/C:/workfolder/promo.service/build/jpa/classes/META-INF/test.persistence.xml
INFO - AltDD ejb-jar.xml ->
file:/C:/workfolder/promo.service/build/jpa/classes/META-INF/test.ejb-jar.xml
INFO - AltDD persistence.xml ->
file:/C:/workfolder/promo.service/build/jpa/classes/META-INF/test.persistence.xml
INFO - AltDD ejb-jar.xml ->
file:/C:/workfolder/promo.service/build/jpa/classes/META-INF/test.ejb-jar.xml
But I still get the same error. If I just remove all those test.* files and
make my persistence.xml valid for my test setup, then everything runs
without error.
Any ideas? I would really like to use this openejb.altdd.prefix to specify
different persistence units if I could.
Please let me know if you need any more information. I could probably make a
simple test case to reproduce this if required as well....
