> I'm start to use hibernate/jpa. I get the following problem:
> orm.xml:
> =====  BEGIN ===
> <?xml version="1.0" encoding="UTF-8"?>
> <entity-mappings version="1.0" xmlns="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd">
> <!-- entity class="TestIdClass" access="FIELD" -->
> <entity class="TestIdClass">
> <attributes >
> <id name="testId">
> <generated-value strategy="IDENTITY"/>
> </id>
> </attributes>
> </entity>
> </entity-mappings>
> ===== END ===
> TestIdClass.java:
> =====  BEGIN ===
> public class TestIdClass {
> public Integer testId;
> //public Integer getTestId() {
> //return testId;
> //}
> public void setTestId(Integer testId) {
> this.testId = testId;
> }
> }
> ===== END ===
> test function:
> =====  BEGIN ===
> static public void testJPA() {
> configuration = new Ejb3Configuration();
> Map map = null;
> String str = null;
> // here error - without getter ->
> // javax.persistence.PersistenceException: [PersistenceUnit: TestHibId] Unable to configure EntityManagerFactory
> configuration = configuration.configure(str, map);
> hibernateConfig = configuration.getHibernateConfiguration();
> // here error - without setter ->
> // org.hibernate.PropertyNotFoundException: Could not find a setter for property testId in class TestIdClass
> sessionFactory = hibernateConfig.buildSessionFactory();
> }
> ===== END ===
> if getTestId - getter commented I get exception. As I think I spend  too much time to find what was a reason of the problem:
> access="FIELD" - resolve the problem, but this solution isn't so obvious, especially if stack trace exception says:
> ===
> Unable to configure EntityManagerFactory
> org.hibernate.AnnotationException: No identifier specified for entity: TestIdClass
> ===
> for me it looks weird - cause I was strongly believe what I specify id here!
> It will be nice I hibernate throws more information with the error or even suggestion to check access value...
> I use latest versions of hibernate jars.
