eclipse bytecode enhancer ignoring annotations
----------------------------------------------

                 Key: OPENJPA-1887
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1887
             Project: OpenJPA
          Issue Type: Bug
          Components: Enhance
    Affects Versions: 1.2.2
         Environment: windows xp, eclipse 3.5 bytecode enhance OpenJPA Eclipse Feature 1.0.0.201001181728
OpenJPA 1.2.2
            Reporter: wendy gibbons


This is long and very detailed as it is the result of a discussion on http://openjpa.208410.n2.nabble.com/beans-Enitiy-annotation-and-bytcode-enhancement-td5380244.html#a5744274

when i use the eclipse bytecode enhancer the annotation @Entity(name="testTable") is ignored
and all youhave available if the class name

BEAN:
@Entity(name="testTable")
@Table(name = "cocktails") 
public class TestBean implements IBean{

	Integer id;
    String data1;
   
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", unique = true, nullable = false)
    public Integer getId() {
            return id;
    }
   
    public void setId(Integer id_) {
            id = id_;
    }
   
    @Column(name="name")
    public String getData1() {
            return data1;
    }
   
    public void setData1(String data1_) {
            data1 = data1_;
    }
}

DAO:
public class TestDAO extends BaseDAO<TestBean> {

	@Override
	public List<TestBean> findAll() {
		return findAll("testTable");
	}
}

main:
public static void main(String[] args) {
		TestDAO dao = new TestDAO();
		List<TestBean> findAll = dao.findAll();
		for (TestBean testBean : findAll) {
			System.out.println(testBean.getData1());
		}
		
	}

persistence.xml:
<persistence-unit name="TestPU"
		transaction-type="RESOURCE_LOCAL">
		<provider>
			org.apache.openjpa.persistence.PersistenceProviderImpl
		</provider>
		<class>com.test.dao.Cocktail</class>
		<class>com.test.dao.TestBean</class>
...

creating a main and selecting from TestBean (no enhancement) i get:

16-Nov-2010 15:42:03 com.test.dao.EntityManagerHelper log
INFO: finding allTest
110  TestPU  INFO   [main] openjpa.Runtime - Starting OpenJPA 1.2.2

781  TestPU  INFO   [main] openjpa.Enhance - Creating subclass for "[class com.test.dao.Cocktail,

will consume more memory than it would if you ran the OpenJPA enhancer. Additionally, lazy
loading will not be available for one-to-one and many-to-one persistent attributes in types
using field access; they will be loaded eagerly instead.

running using the runtime enhancer: (putting -javaagent:C:\JavaProjects\OpenJpaTest\WebContent\WEB-INF\lib\openjpa-1.2.2.jar
in the run configuration arguments)

1860  TestPU  TRACE  [main] openjpa.jdbc.SQL - <t 3841429, conn 4176892> [31 ms] spent


And using the eclipse bytecode enhancer plugin:

16-Nov-2010 15:45:32 com.test.dao.EntityManagerHelper log

109  TestPU  INFO   [main] openjpa.Runtime - Starting OpenJPA 1.2.2

SEVERE: find all  failed name failed

An error occurred while parsing the query filter "select model from testTable model order
by model.id". Error message: The name "testTable" is not a recognized entity or identifier.
Perhaps you meant TestBean, which is a close match. Known entity names: [TestBean, Cocktail]
        at org.apache.openjpa.kernel.exps.AbstractExpressionBuilder.parseException(AbstractExpressionBuilder.java:118)
.

Trying now with the latest version of openjpa jar
