Messieurs-dames,
As I could not find much clues about the right way to do it, here I come:
I'm trying to get an EntityManagerFactory properly setup from the
Persistence class, but I cannot get further than the following exception
javax.persistence.PersistenceException: No Persistence provider for
EntityManager named teamplay_test
at javax.persistence.Persistence.createEntityManagerFactory(
Persistence.java:89)
at com.gdteam.teamplay.domain.manager.TeamplayEMFactoryManager.get (
TeamplayEMFactoryManager.java:60)
at com.gdteam.teamplay.test.persistence.PersistenceUtilTest.setUp(
PersistenceUtilTest.java:19)
at junit.framework.TestCase.runBare(TestCase.java:125)
at junit.framework.TestResult$1.protect (TestResult.java:106)
at junit.framework.TestResult.runProtected(TestResult.java:124)
at junit.framework.TestResult.run(TestResult.java:109)
at junit.framework.TestCase.run(TestCase.java:118)
at junit.framework.TestSuite.runTest(TestSuite.java:208)
at junit.framework.TestSuite.run(TestSuite.java:203)
Here is the code part that leads to the exception:
public class TeamplayEMFactoryManager {
...
private final Map<String, String> props = new HashMap<String, String>();
private final Map<String, EntityManagerFactory> map = new
HashMap<String, EntityManagerFactory>();
...
private TeamplayEMFactoryManager() {
props.put("openjpa.ConnectionDriverName", "org.hsqldb.jdbcDriver");
props.put("openjpa.ConnectionUserName", "sa");
props.put("openjpa.ConnectionPassword", "");
props.put("openjpa.Log", "DefaultLevel=WARN, Tool=INFO");
props.put("openjpa.MetaDataFactory", "jpa(Types="+buildTypes()+")");
}
..
public EntityManagerFactory get(String url) {
EntityManagerFactory factory = null;
if (null == url || url.length() == 0 ) {
url = "default";
}
factory = this.map.get(url);
if (null == factory) {
if ( "default".equals(url)) {
1- factory = Persistence.createEntityManagerFactory(null);
} else {
Map<String , String> map = new HashMap<String,
String>(props);
map.put("openjpa.ConnectionURL ", buildUrl(url));
2- factory = Persistence.createEntityManagerFactory(url,map);
}
this.map.put(url, factory);
}
return factory;
}
...
}
Note :
I'm using a persistence.xml for single persitence unit creation, and this
test works fine. I've had a dive into the source code, and found the
provider is lookuped and found by the glassfish persistence implementation
class. The exception is raised on the open jpa side, and I know I'm missing
some configuration elements, but I cannot guess what's missing?
any hint?
thank you guys
