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

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.

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]

Trying now with the latest version of openjpa jar
