java.lang.NoClassDefFoundError: net/sf/ehcache/CacheExceptio

Hi

In Seam Gen-generated project, I want to Unit Testing a stateful Seam component.
I want to create EntityManager in Unit Testing Code for injecting it in the Seam component with SeamTest#setField().

Running "ant test", java.lang.NoClassDefFoundError is thrown at this code.

public class FooTest extends SeamTest {
 ... ...
 @Test
 public void testFind() {
 EntityManagerFactory emf = Persistence.createEntityManagerFactory("myproject");
 ... ...
 }
 ... ...
}

"myproject" is persistence unit name defined in "resources/META-INF/persistence-test.xml".
