I have one bean called Resource that has a blob, but other than that there is nothing special about it.

I have another bean called StandardProduct that is subclass of a Product POJO there are some eager clobs with it. Other than that there is nothing special about it either.

When I run my test harnass on my session facade that manages these, I get a different result when I try to remove each of these entity beans.

For my Resource Facade, here is my test code:

 public void testCrud() {
 try {
 Resource resource = new Resource();
 Date date = new Date();
 byte[] data = new byte[]{4,3,2,1,2,3,4,6,13};
 String description = "description";
 String mimeType = "img/gif";
 String name = "name.gif";
 String notes = "notes";

 resource.setByteArray(data);
 resource.setCreatedDate(date);
 resource.setDescription(description);
 resource.setMimeType(mimeType);
 resource.setName(name);
 resource.setNotes(notes);
 resource.setUpdatedDate(new Date());

 InitialContext ctx = getInitialContext();

 ResourceFacadeLocal local = (ResourceFacadeLocal)
 ctx.lookup("ResourceFacadeBean/local");

 local.create(resource);

 resource = local.findByPrimaryKey(resource.getId());
 assertEquals(date, resource.getCreatedDate());
 assertEquals(date, resource.getUpdatedDate());
 ArrayAssert.assertEquals(data, resource.getByteArray());
 assertEquals(description, resource.getDescription());
 assertEquals(mimeType, resource.getMimeType());
 assertEquals(name, resource.getName());
 assertEquals(notes, resource.getNotes());

 String newDescription = "New Desciption";
 resource.setDescription(newDescription);

 local.update(resource);
 resource = local.findByPrimaryKey(resource.getId());
 assertEquals(newDescription, resource.getDescription());

 local.remove(resource);
 resource = local.findByPrimaryKey(resource.getId());
 assertNull(resource);
 } catch (Throwable e) {
 e.printStackTrace();
 fail(e.getMessage());
 }
 }

If you notice that as one of the last items there I have assertNull(resource), this tests and resolves to true and all is well.

Testing for a StandardProduct Facade, I do almost the same thing.

 public void testSimpleStandardProduct() {
 try {
 InitialContext ctx = getInitialContext();

 StandardProductFacadeLocal local = (StandardProductFacadeLocal)
 ctx.lookup("StandardProductFacadeBean/local");

 StandardProduct standardProduct = new StandardProduct();
 setSampleValues(standardProduct);

 local.create(standardProduct);
 assertNotNull(standardProduct.getId());
 standardProduct = local.findByPrimaryKey(standardProduct.getId());

 assertEquals(true, standardProduct.getAvailable());
 assertEquals(true, standardProduct.getCallForPrice());
 assertEquals(sampleDate, standardProduct.getCreatedDate());
 assertEquals("description",standardProduct.getDescription());
 assertEquals(12.0f ,standardProduct.getHeight());
 assertEquals(12.0f ,standardProduct.getLength());
 assertEquals("foo" ,standardProduct.getName());
 assertEquals("notes" ,standardProduct.getNotes());
 assertEquals(143.00f ,standardProduct.getPrice());
 assertEquals("subtype" ,standardProduct.getSubtype());
 assertEquals("type" ,standardProduct.getType());
 assertEquals(124.00f,standardProduct.getUpcharge());
 assertEquals(sampleDate,standardProduct.getUpdatedDate());
 assertEquals("http://www.cool.com",standardProduct.getUrl());
 assertEquals(144.00f,standardProduct.getWeight());
 assertEquals(122.00f ,standardProduct.getWidth());

 standardProduct.setName("bar");
 local.update(standardProduct);
 assertNotNull(standardProduct.getId());
 standardProduct = local.findByPrimaryKey(standardProduct.getId());

 assertEquals("bar", standardProduct.getName());

 local.remove(standardProduct);
 standardProduct = local.findByPrimaryKey(standardProduct.getId());
 assertNull(standardProduct);
 } catch (NamingException ne) {
 ne.printStackTrace();
 fail("NamingException thrown" + ne.getMessage());

 } catch (Throwable e) {
 e.printStackTrace();
 fail("Exception thrown" + e.getMessage());

 }
 }

The difference now is that I get:

javax.ejb.EJBException: javax.persistence.NoResultException: No entity found for query
 at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:69)
 at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:83)
 at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:192)
 at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:98)

Both results make sense, but they are inconsistent. Is there something I am not understanding about the spec? or is this a problem. I must include that before this I received a ClassNotFound ANTLR/ANTLRException.
