Unable to configure EntityManagerFactory - No identifier specified for entity - exception in case if class has no getter ------------------------------------------------------------------------------------------------------------------------ Key: EJB-440 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-440 Project: Hibernate Entity Manager Issue Type: Improvement Components: EntityManager Reporter: Vitali Yemialyanchyk Priority: Minor Attachments: screenshot-1.jpg 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
