[JBoss-user] [Persistence CMP/JBoss] - Method is not a known CMP field accessor, CMR field accessor
Hi, I've got a bunch of CMPs (running on JBoss 3.2.5) representing an order
with orderLine. Here are the links:
Order -1*- OrderLine -11- Item
|
V
Customer
My problem comes when I want to create an order. With existing Customer and
Items, I want to create (in one go) an Order with its OrderLines. When I do
that I've got the following exception
15:53:01,187 ERROR [LogInterceptor] TransactionRolledbackException in method:
public abstract java.lang.String com.yaps.

I've localised the problem but I can't solve it or explain it. It's in the
postCreate of the OrderLine CMP when it calls the setOrder method. If I take it
our, the exception doesn't occur but in the database I've got a foreign key set
to null, normal.
public String ejbCreate(int quantity, double unitCost, OrderLocal order,
ItemLocal item) throws CreateException, CheckException {
|
| setId(getUniqueId(COUNTER_NAME));
| setUnitCost(unitCost);
| setQuantity(quantity);
| return null;
| }
|
| public void ejbPostCreate(int quantity, double unitCost, OrderLocal
order, ItemLocal item) throws CreateException, CheckException {
|
| setOrder(order);
| setItem(item);
| }
The method setOrder IS a CMR Method and it's declared abstract like all the
other getters and setters
public abstract int getQuantity();
| public abstract void setQuantity(final int quantity);
|
| public abstract double getUnitCost();
| public abstract void setUnitCost(final double unitCost);
|
| public abstract OrderLocal getOrder();
| public abstract void setOrder(final OrderLocal order);
|
| public abstract ItemLocal getItem();
| public abstract void setItem(final ItemLocal item);

[JBoss-user] [Persistence CMP/JBoss] - Re: Method is not a known CMP field accessor, CMR field acce
I've finally found the problem, I didn't take in account that the Order - OrderLine relationship was bidirectional. Here is the ejb-jar.xml that works, I've just added the cmr-field | cmr-field-nameorder/cmr-field-name | /cmr-field It looks like that ejb-relation | ejb-relation-nameOrderBean - OrderLineBean/ejb-relation-name | ejb-relationship-role | ejb-relationship-role-nameorder-has-orderLines/ejb-relationship-role-name | multiplicityOne/multiplicity | relationship-role-source | ejb-nameOrderBean/ejb-name | /relationship-role-source | cmr-field | cmr-field-nameorderLines/cmr-field-name | cmr-field-typejava.util.Collection/cmr-field-type | /cmr-field | /ejb-relationship-role | | ejb-relationship-role | ejb-relationship-role-nameorderLine-belongs_to-order/ejb-relationship-role-name | multiplicityMany/multiplicity | relationship-role-source | ejb-nameOrderLineBean/ejb-name | /relationship-role-source | cmr-field | cmr-field-nameorder/cmr-field-name | /cmr-field | /ejb-relationship-role | /ejb-relation View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3865233#3865233 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3865233 --- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

[JBoss-user] [Persistence CMP/JBoss] - CMP With object attributes
Hi,
I've got existing POJO/DAO classes and I'm converting them into CMP Beans.
Works fine. I've reached the case where I have a class Customer with an
attribute Address (another class).
public final class Customer extends PersistentObject {
private String _id;
private String _firstname;
private String _lastname;
private final Address _address = new Address();
}
public final class Address {
private String _street1;
private String _city;
private String _zipcode;
}
To turn that into a CMP you would thing 'well, let's create 2 CMPs, one for
Customer and one for address with a relation'. The problem is that I only have
one DB Table t_customer with all attributes, but there's not table for address
CREATE TABLE T_CUSTOMER( id VARCHAR(10), PRIMARY KEY(id), firstname VARCHAR(50)
NOT NULL, lastname VARCHAR(50) NOT NULL, street1 VARCHAR(50), city VARCHAR(25),
zipcode VARCHAR(10));
And I don't want to create a second table (t_address). How can I use a CMP and
map its composed attributes (address) into the table t_customer ? If I creat a
BMP instead I will have problems with relationship between CMPs and BMPs.
Any help, thanks,
Antonio

[JBoss-user] [Persistence CMP/JBoss] - Re: Bean not found for relation
Thanks, I've put all the entities in only one jar with only one deployment descriptor and it's working fine. Is the constraint both beans have to be defined in the same dd if you have a cmr relationship between them defined in the spec (I haven't found anything) or is this a JBoss limitation ?
