      Description

      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, class com.test.dao.TestBean]". This means that your application will be less efficient and 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.

      1610 TestPU TRACE [main] openjpa.jdbc.SQL - <t 31212095, conn 25254907> [16 ms] spent

      running using the runtime enhancer: (putting -javaagent:C:\JavaProjects\OpenJpaTest\WebContent\WEB-INF\lib\openjpa-1.2.2.jar in the run configuration arguments)
      16-Nov-2010 15:44:11 com.test.dao.EntityManagerHelper log

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

      Trying now with the latest version of openjpa jar tested with openJPA 2.0.1, and this also fails

          Wendy -

          As I mentioned before, I found that the eclipse enhancer isn't working[1] as advertised. I'd suggest using the maven plugin, or use the ant based enhancer[2].
