Hi, guys,I'm pretty new to Enterprise Java, Maven, and this kind of
development whatsover, so it's pretty possible that I'm just making some
kind of beginner's mistake, so bear with me, please.What I'm trying to do:
I'm developing a J2EE application, that will eventually run on RedHat's
OpenShift (therefore JBoss AS 7.1, Hibernate, MySQL). I would like to write
some tests for my EJBs and from googling the topic I've figured out, that
OpenEJB could help me.I've added following Maven dependency:
<dependency>
<groupId>org.apache.openejb</groupId>
<artifactId>openejb-core</artifactId>
<version>4.5.2</version>
<scope>test</scope>
</dependency>
Now I have this dummy Stateless EJB called Foo:
package cz.drekorian.ffmap;import javax.ejb.Stateless;@Statelesspublic class
Foo { public int bar() { return 1; }}
And to test whether things are working or not, I've written a JUnit 4 test:
package cz.drekorian.ffmap.test.entities;import
javax.ejb.embeddable.EJBContainer;import javax.naming.NamingException;import
junit.framework.Assert;import org.junit.AfterClass;import
org.junit.Before;import org.junit.BeforeClass;import org.junit.Test;import
cz.drekorian.ffmap.Foo;public class FooTest { private static EJBContainer
ejbContainer; private Foo foo; public FooTest() { }
@BeforeClass public static void setUpClass() { ejbContainer =
EJBContainer.createEJBContainer(); } @AfterClass public static
void tearDownClass() { if (ejbContainer != null) {
ejbContainer.close(); } } @Before public void setUp()
throws NamingException { foo = (Foo)
ejbContainer.getContext().lookup("java:global/ffmap/Foo"); } @Test
public void testBar() { Assert.assertEquals(1, foo.bar()); }}
The JUnit test fails on java.lang.NullPointerException. Here's the trace:
java.lang.NullPointerException at

Any help or advice would be greatly appreciated.Thanks.
