Composite and Overlapping PK

[prabhumadanagopal]

Sorry for posting again..
I have a problem in Composite n Overlapping PK with @EmbeddedId tags
Is there any other JBOSS specific annotations I need to use? like @Dependable.. Is there any sample code that shows Composite and Overlapping PK mapping?

I am using JBoss 4.0.4 GA.

Please have a look at the code snippets and the exception I get.

Code starts--here--
@IdClass(com.x.ejb.entity.impl.UserGroupKey.class)
@Entity
public class UserGroup {
...

@Id
@Column(name="GROUPID",
insertable=false, updatable=false)
public String getGroupId() {
return groupId;
}
...
@Id
@Column(name="USERID",
insertable=false, updatable=false)
public String getUserId() {
return userId;
}
...
@EmbeddedId
public UserGroupKey getPrimaryKey() {
return primaryKey;
}
Code ends--here--

And UserGroupKey is Embeddable

On deploying I get
org.hibernate.MappingException: Repeated column in mapping for entity: com.x.ejb.entity.impl.UserGroup column: groupId (
should be mapped with insert="false" update="false")

Thnks, Prabhu

Why do you use the primaryKey property ?

You can do this :

@IdClass(com.x.ejb.entity.impl.UserGroupKey.class)
@Entity
public class UserGroup {
...

@Id
@Column(name="GROUPID",
insertable=false, updatable=false)
public String getGroupId() {
return groupId;
}
...
@Id
@Column(name="USERID",
insertable=false, updatable=false)
public String getUserId() {
return userId;
}
...
// don't use this
/***********************************
@EmbeddedId
public UserGroupKey getPrimaryKey() {
return primaryKey;
}
