OpenEJB - configuring datasource for JUnit

Question

I have problem with proper configuration of datasource for OpenEJB 3.1.3. I try to configure connection to postgres db, but hen I debug test I get default hsql connection parameters. Here is my test class: ``` @RunWith(ApplicationComposer.class) public class OpenEJBTest { @EJB Files fb; @Test public void testSth() { List<UploadSession> uploadNotFinishedSessions = fb.getUploadNotFinishedSessions(); } @Module public EjbJar beans() { EjbJar ejbJar = new EjbJar("beans"); ejbJar.addEnterpriseBean(new StatelessBean(FilesBean.class)); ejbJar.addEnterpriseBean(new StatelessBean(FilesUtilBean.class)); ejbJar.addEnterpriseBean(new StatelessBean(ServerFilesBean.class)); ejbJar.addEnterpriseBean(new StatelessBean(UserUtilBean.class)); return ejbJar; } @Module public PersistenceUnit persistence() { PersistenceUnit unit = new PersistenceUnit("postgresPU", HibernatePersistence.class.getName()); String simpleXml = SimpleXmlUtil.toSimpleXml(unit); System.out.println(simpleXml); unit.setJtaDataSource("…

Accepted Answer

The `ApplicationComposer` doesn't use JNDI to bootstrap the container so the `jndi.properties` file is never seen.

What you can do instead is use the `org.apache.openejb.junit.Configuration` annotation on a method to have it return the properties you want to use to configure the test.

```
@Configuration
public Properties properties() {
   //...
}
```

I'd rename `jndi.properties` to something else so it isn't confusing, then you can use code like this to find it in the classpath.

```
   final URL url = this.getClass().getResource("/config.properties");
   final Properties props = new Properties();
   final InputStream in = url.openStream();
   try {
       props.load(in);
   } finally {
       close(in);
   }
```
