[jboss-jira] [JBoss JIRA] Updated: (EJBTHREE-935) Cannot have several EAGER-fetches in one class

Cannot have several EAGER-fetches in one class ---------------------------------------------- Key: EJBTHREE-935 URL: http://jira.jboss.com/jira/browse/EJBTHREE-935 Project: EJB 3.0 Issue Type: Bug Environment: JBoss 4.0.5.GA, JBoss EJB3 RC9 Patch 1 on WIndows Vista Ent. Ed. MySQL without InnoDB Reporter: Oskar Carlstedt It is impossible to use FetchType.EAGER on more than one set in an Entity bean. Here is an example: public class SomeClass { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") private Integer id; ... @OneToOne(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.EAGER) private OneToOneTest oneToOneTest; @OneToMany(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.LAZY) private List<OneToManyTest1> oneToManyTest1 = new ArrayList<OneToManyTest1>(); @OneToMany(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.EAGER) private List<OneToManyTest2> oneToManyTest2 = new ArrayList<OneToManyTest2>(); @OneToMany(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.EAGER) private List<OneToManyTest3> oneToManyTest3 = new ArrayList<OneToManyTest3>(); ... } Deploying this application will fail with the following message: 2007-04-02 16:02:11,694 WARN [org.jboss.system.ServiceController] Problem starting service
