embeddable

I am using the embeddable EJB container of WebSphere 8 to write some unit tests for my EJBs with JUnit4. My IDE is the RAD 8. Here is my simple test code snippet: Map properties = new HashMap(); properties.put(EJBContainer.PROVIDER, "com.ibm.websphere.ejbcontainer.EmbeddableContainerProvider"); EJBContainer ec = EJBContainer.createEJBContainer(properties); I get a NoClassDefFoundError: java.lang.NoClassDefFoundError: com/ibm/ejs/ras/hpel/HpelHelper at com.ibm.ejs.ras.RasHelper.getThreadId(RasHelper.java:1760) at com.ibm.ejs.ras.RasEvent6$1.initialValue(RasEvent6.java:101) at java.lang

I have fairly typical scenario where there is a main @Entity and everything inside him is embeddable (so everything inside doesn't make sense without the parent). Now JPA 2.0 is blocking me to nest a @ElementCollection inside a @Embeddable defined in another @ElementCollection: JSR-317 2.6 Collections of Embeddable Classes and Basic Types An embeddable class (including an embeddable class within another embeddable class) that is contained within an element collection must not contain an element collection, nor may it contain a relationship to an entity other than a many-to-one or one-to-one

I am using eclipselink for JPA . I have an entity, which has a composite key fabricated out of two fields. Following is my Embeddable primary key class' fields(members). @Embeddable public class LeavePK { @ManyToOne(optional = false) @JoinColumn(name = "staffId", nullable = false) private Staff staff; @Temporal(TemporalType.TIMESTAMP) private Calendar date; //setters and getters } My entity is going to hold leave data related to a staff, so I am trying to combine staff object and leave date to produce composite key. Apart from my logic, it is not allowing me to have a foreign key mapping

I created an entity "Person" in Doctrine2, and I added to it an Adress entity, which is a value object (embeddable). I want to allow a Person creation, without an Address, so I tag my embedded as "nullable = true". But on the other hand, my Address entity, if it exists, SHOULD contains at least some information (like city, zip code, etc...). So it has "nullable = false" attributes. Address: type: embeddable fields: [...] city: type: string length: 255 nullable: false Person: type: entity table: null embedded: address: class: Address nullable: true It seems that the "nullable = true" of the

I have class Money which is an @Embeddable @Embeddable public class Money implements Serializable, Comparable<Money> { @Column(name = "amount", precision = 15, scale = 2) private BigDecimal amount; } When I useit multiple time inside entity, everything works fine. For example @Entity public class SomeEntity implements Serializable { @Embedded @AttributeOverride(name = "amount", column = @Column(name = "entry")) private Money entryValue; @Embedded @AttributeOverride(name = "amount", column = @Column(name = "leave")) private Money leaveValue; } Code above works perfectly. Now the problem occurs

We are translating old xml based configuration to Annotation based configuration Situation There is a class which is annotated as @Embeddable(ParentPk.java) , another class extends this class which is @Embeddable(ChildPk.java) , this ChildPk.java is used as composite primary key in SomeOwnerClass.java , Which have foreign relation with another class SomeChildTable.java and tends to use properties col1 and col2 which are available in parent class of ChildPk.java but when query is executed hibernate does not finds col1 and col2 rather if I copy col1 and col2 in ChildPk.java from parent class

I'm currently struggling with the right mapping annotations for a scenario using a composite Primary Key Class. First, what I am trying to achieve in words: I have 2 classes: group and FieldAccessRule. A Group can have many FieldAccessRules, while a FieldAccessRule only has ONE Group assigned. Modling this is not a problem so far (simplified): public class Group{ ... @OneToMany(mappedBy = "group") private Set<FieldAccessRule> fieldAccessRules; ... } and for the FieldAccessRule: public class FieldAccessRule { ... @ManyToOne @JoinColumn(name = "group_id") private Group group; ... } Now, I
