Hello everyone,
i'm desperatly trying to write a simple CMR between two Entity Beans using XDoclet and
the additional challenge of using unkown primary keys :)
I have two beans, a User and a Folder bean. Every User has a folder but not every
Folder belongs to a user.
My code so far:
UserBean.java
/**
| * @ejb.bean
| * name = "User"
| * schema = "UserSchema"
| * jndi-name = "User";
| * description = "A User Bean"
| * type = "CMP"
| * cmp-version = "2.x"
| * @ejb.pk
| * class = "java.lang.Object"
| * generate = "false"
| * ---
| * @jboss.unknown-pk
| * class = "java.lang.Integer"
| * column-name = "user_id"
| * auto-increment = "true"
| * sql-type = "INTEGER"
| * jdbc-type = "INTEGER"
| * @jboss.persistence
| * pk-constraint = "false"
| * remove-table = "true"
| * @jboss.entity-command
| * name = "hsqldb-fetch-key"
| */
| public abstract class UserBean implements EntityBean {
| ...
| /**
| * @ejb.interface-method
| * @ejb.relation
| * name = "USER-has-one-FOLDER"
| * role-name = "Every USER has one FOLDER"
| * target-ejb = "Folder"
| * target-role-name = "Some FOLDER belong to a USER"
| * target-cascade-delete = "yes"
| * ---
| * @jboss.relation
| * related-pk-field = "folder"
| * fk-column = "folder_id"
| * dbindex = "true"
| *
| */
| public abstract Folder getFolder();
| }
Folder.java
/**
| * @ejb.bean
| * name = "Folder"
| * schema = "FolderSchema"
| * jndi-name = "Folder";
| * description = "A Folder Bean"
| * type = "CMP"
| * cmp-version = "2.x"
| * @ejb.pk
| * class = "java.lang.Object"
| * generate = "false"
| * ---
| * @jboss.unknown-pk
| * class = "java.lang.Integer"
| * column-name = "folder_id"
| * auto-increment = "true"
| * sql-type = "INTEGER"
| * jdbc-type = "INTEGER"
| * @jboss.persistence
| * pk-constraint = "false"
| * remove-table = "true"
| * @jboss.entity-command
| * name = "hsqldb-fetch-key"
| */
| public abstract class FolderBean implements EntityBean {
| ... (nothing specific to the relation)
| }
This however gives me a DeploymentException:
Role 'Some FOLDER belong to a USER' on Entity Bean 'Folder' : CMP field for key not
found: field name='folder_id'
I assume because of me using an unknown primary key its field is not a normal CMP
field or something...
Is there a way to work around this?
Does anyone know more?
Thanks for the help,
Stud
