Unidirectional one-to-many CMR in OC4J 9.0.3.1699
Hi,
I have the following issue with the new (productiv) OC4J 9.0.3 build 020927.1699, with did not occur with
build 020725.1695. I would like to deploy local entity beans CMRDepartment -1--n-> CMREmployee with container managed relations. Here's the relation part of ejb-jar.xml
<ejb-relation>
<ejb-relation-name>theEmployees2theDepartment</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>theEmployees</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source>
<ejb-name>CMREmployee</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>theDepartment</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source>
<ejb-name>CMRDepartment</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>theEmployees</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
</ejb-relation>
Now the problem is that the depoyment generates an database table CMREmployee_cmrtest_cmrtest for CMR with a foreign key column CMRDepartment_theEmployees referencing the CMRDepartment_cmrtest_cmrtest table for the CMRDepartment bean, even though the relation is not navigable from Emp to Dept. Is this a bug or a feature? Here's the CMREmployee part of the orion-ejb-jar.xml after deployment:
<entity-deployment name="CMREmployee" location="CMREmployee" wrapper="CMREmployeeHome_EntityHomeWrapper27" local-wrapper="CMREmployeeLocalHome_EntityHomeWrapper16" table="CMREmployee_cmrtest_cmrtest" data-source="jdbc/OracleDS" exclusive-write-access="false" locking-mode="optimistic" update-changed-fields-only="true" delay-updates-until-commit="true" min-instances-per-pk="0" max-instances-per-pk="50" disable-wrapper-cache="true">

</cmp-field-mapping>
<finder-method>

Any hints would be very wellcome.

Trond,
when ou deploy your application, you should not need to include the orion-ejb-jar.xml.
Also, if you have previously deployed the application, delete the application directory UNDER both applicatopn-deployments and applications. The directory will be your application's name.
Hope this helps,

Unidirectional one-to-many with join table
According to http://docs.jboss.org/hibernate/orm/3.5/reference/en-US/html/associations.html#assoc-unidirectional-12m "A unidirectional one-to-many association on a foreign key is an unusual case, and is not recommended", instead they recommend using a join table, e.g.
create table Person ( personId bigint not null primary key )
create table PersonAddress ( personId not null, addressId bigint not null primary key )
create table Address ( addressId bigint not null primary key )
However if doing this, when using SQLDeveloper the Address table does not appear as a child table of Person, which it should be as a unidirectional one-to-many meaning that I can't create a cache group for Person and subsequently Person.
Is this something that can be worked around as I'm using a legacy schema created from Hibernate/JPA and the implications of changing are quite substantial?
ThanksHi Gennady,
Apologies but my question was not clear enough. The schema structure that I have inherited is as follows:
CREATE TABLE T_PERSON ( PERSONID NUMBER PRIMARY KEY, PERSONFIRSTNAME VARCHAR2(20), PERSONLASTNAME VARCHAR2(20) );
CREATE TABLE T_PERSONADDRESS (PERSONID NUMBER NOT NULL, ADDRESSID NUMBER NOT NULL PRIMARY KEY );
CREATE TABLE T_ADDRESS ( ADDRESSID NUMBER PRIMARY KEY, ADDRESSTEXT VARCHAR2(200) );
ALTER TABLE T_PERSONADDRESS ADD CONSTRAINT FK_PERSON_ADDR_PERSON_ID FOREIGN KEY (PERSONID) REFERENCES T_PERSON(PERSONID);
ALTER TABLE T_PERSONADDRESS ADD CONSTRAINT FK_PERSON_ADDR_ADDR_ID FOREIGN KEY (ADDRESSID) REFERENCES T_ADDRESS(ADDRESSID);This is implementing a unidirectional one-to-many relationship between T_PERSON and T_ADDRESS according to the Hibernate and JPA recommendation. As far as I can see most schema designers would do this using by adding a column "PERSON_ID" (and associated FK) on the T_ADDRESS table and therefore not needing the T_PERSONADDRESS table.
This being what it is, I would then like to create a cache-group as follows:
CREATE READONLY CACHE GROUP "CACHEGROUPADDRESSES"
AUTOREFRESH MODE INCREMENTAL INTERVAL 5 MINUTES
STATE PAUSED
FROM
"SCHEMA1"."T_PERSON" (
"PERSONID" NUMBER NOT NULL,
"PERSONFIRSTNAME" VARCHAR2(20 BYTE),
"PERSONLASTNAME" VARCHAR2(20 BYTE),
PRIMARY KEY("PERSONID")
"SCHEMA1"."T_ADDRESS" (
"ADDRESSID" NUMBER NOT NULL,
"ADDRESSTEXT" VARCHAR2(20 BYTE),
PRIMARY KEY("ADDRESSID")
"SCHEMA1"."T_PERSONADDRESS" (
"PERSONID" NUMBER NOT NULL,
"ADDRESSID" NUMBER NOT NULL,
PRIMARY KEY("ADDRESSID"),
FOREIGN KEY("PERSONID")
REFERENCES "SCHEMA1"."T_PERSON"("PERSONID"),
FOREIGN KEY("ADDRESSID")
REFERENCES "SCHEMA1"."T_ADDRESS"("ADDRESSID")
)This however gives me the error "TT8222: Multiple parent tables found" because TimesTen has failed to identify the one-to-many-using-link-table pattern.
Without a schema re-write is there anything that I can do, alternatively will this be looked at for a future release of TimesTen?

I am trying to get Container Managed Relationships working with Oracle Application Server. I am sure that the problem it quite obvious to anyone who has got this working before, but after carefully following numerous examples, I still cant get them to work. I have various issues including the application server blocking when it calls the getB() method in "A" to populate the items from table "B", even though the generated SQL looks okay e.g., "select B_PK from B where (b_fk = 1)".
I would be extremely grateful if you could point out my (hopefully obvious) mistake as I wrestled with it for the past couple of weeks.
Any ideas?
Cheers,
Jonathan
I have two tables A and B; A has a one-to-many relationship with B:
Table A:
A_PK (primary key)
A_NAME
Table B:
B_PK (primary key)
B_NAME
B_FK (foreign key to table A)

p = home.create("Violetta");
p.addNewPet("Jenny");
p = home.create("Frank");
p.addPet("Jenny");
p.addPet("Jenny");
May this be a timing problem? Or is there a command I could execute to ensure all data manipulation is populated to the DB. (Like close() in JDBC)

Unidirectional one-to-many relationship without a join table
Hello,
I have 2 classes, Invoice and InvoiceLine, and a one-to-many unidirectional relationship from Invoice to InvoiceLine. By default, with JPA, it would be mapped by a join table with foreign keys that refer to the 2 tables which represent Invoice and InvoiceLine.
My problem: the database has already a foreign key in the table which represents InvoiceLine that refers to the table which represents Invoice.
To solve my problem I could make the relationship bidirectional but I would like to know if it is possible to keep it unidirectional and to use the foreign key which already exists (in the table that represents InvoiceLine). How could I declare the mapping with JPA?
Thanks in avance for your answers.JPA requires that any @OneToMany mapping not using a join table have an inverse @ManyToOne mapping. In general the foreign key in the target object needs to be mapped and a @ManyToOne mapping is normally the best way to map it, so making the relationship bi-directional is your best option.
There are other ways in TopLink to map a unidirectional 1-m, but these are not directly supported by the JPA spec. You could define a TopLink OneToManyMapping for the relationship through a TopLink DescriptorCustomizer and the code API. You would still need to map the foreign key in the target object some way, but you could use a @Basic mapping for this as long as you keep it in synch.
In TopLink you could also map the relationship using an AggregateCollectionMapping (basically a collection of embeddables), and then not require mapping the foreign key in the target, but this imposes limitations on the target object (must be treated like an embeddable instead of entity). You would also need to configure the target object to be an aggregateCollectionDescriptor if using this option. -
Problem Removing CMP 2.0 Bean from Many side of One-to-Many
I'm getting an exception within the weblogic container when I try to
delete a bean from the many side of a one-to-many CMR.
The two entity beans are called CaseFile and CaseExpert. There are
many CaseExperts for each CaseFile. When you call the remove method
on the CaseExpert, Weblogic throws a null pointer exception when
accessing the EntityCache as shown at the bottom of this message. I'm
using the latest version of Weblogic 7 (WebLogic Server 7.0 Thu Jun
20 11:47:11 PDT 2002 190955). My relationship section of my
ejb-jar.xml file is also shown below.
Any ideas?
Thanks,
David

Hi,
I like to do the following:
1) Map one bean corresponding to table A to many beans corresponding totable
B 2) table B has two columns as the primary keys.
3) One of the primary key column in table B is a foreign key pointing tothe primary
key of table A.
4) bean corresponding to table A has the cmr Collection field
I am not able to map this scenario. I guess the mapping is possible aslong as
each table has its own unrelated primary keys. If anyone has tried this,please...please...help.

One-to many relationship in EJB
hi forum
wish you a very happy and prosperous new year
i want to implement CMR in my project but to start with i tried sample application setting one-to many CMR between EMP and DEPT table of scott/tiger .the problem is i have to modify my orion-ejb-jar.xml how can we do it?Are you using JDeveloper? JDeveloper automatically creates the orion-ejb-jar.xml file when you use the EJB wizard.

Weblogic-cmp-rdbms-jar.xml for One-To-Many unidirectional relationship
hi,
I am trying to create a simple cmp One-To-Many unidirectional relationship and deploy the same in weblogic. Can someone help me with the weblogic-cmp-rdbms-jar.xml. Am attaching the weblogic-cmp-rdbms-jar. xml tht i am using as also the corresponding ejb-jar.xml. Pls. note tht i want a unidirectional relationship here. one i am tryng However i get this error:
Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was: Role 'Supplier supplies Products' of relationship 'Product Supplier' contains an invalid key-column value of 'productID'. The key-column must specify a primary key column in the related bean. However, there is no primary key column named 'productID' defined in the related bean 'ProductEJB' or else 'productID' is not being recognized due to case mismatch. My weblogic-cmp-rdbms-jar

</ejb-jar>I think u r some confusion with productID and SuppliedID . primary key of one column( productId ) can be a foreign key of other table colum( SuppliedID). but foreign key( SuppliedID) can not be a primary key of second table .u declared SuppliedId as primary key . so ur mapping is incorrect.

hi all,
i defined two entity beans, Quiz and Question, with many-to-many cmr and
a table named Quiz_questions_Question_quizesTable is created in the database after deployment process. the formed table columns consist of primary key of Quiz and primary key of Question, as expected. what i want to do is adding one more column to this table that shows the sequence number of the related question in the related quiz. is it possible? and how? or what should i do?
thanks in advance.."what i want to do is adding one more column to this table that shows the sequence number of the related question in the related quiz."
Makes sense, but then the association table is no longer just an association table.
Perhaps a way to get you in the right frame of mind is, "how would you model this with just objects?"
Basically a CMR just represents an association between two objects. You would see in your revised object model that you do not have a simple n-to-n association between a Quiz objects and a Question objects.[Quiz](0..n)---->(1..n)[Question]The above (bastardized UML) model does not represent the enumeration of Question objects within the scope of a single Quiz object.
Perhaps the following is more accurate:[Quiz](1)---->(1..n)[QuizQuestion](0..n)---->(1)[Question]or [Question]
A
|
|
[Quiz](1)---->(1..n)[QuizQuestion]It is only after you have your object model that you should worry about the entity bean stuff. -
EJB relation One to Many - ClassCastException
Hi !
I created two CMP EJB entity Client and Address. There is a One to Many relation between them.
When I deploy them on JBoss, I have no errors, and the correponding tables are created in the database. The EJB seems to work fine, but when I use a 'relation' method : myAddress.setClient(myClient) for instance. I get a ServerException.
In the log of JBoss there is :
ClassCastException : org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCCMRFieldBridge.SetInstanceValue(...)
I think I have a problem in my descriptors or JBoss configuration.
If u have an idea ...
Thxsorry to whack a load of code in but i can't see where the problem is here is my ejb-jar.xml file:

I have downloaded from Orion the Movie EJB application with
OR mapping one-to-many.
When I ran it, it's fine. But I have spurious messages on

at com.evermind.util.ThreadPoolThread.run(ThreadPoolThread.java:62)For EntityOne and EntityTwo you can just define a normal OneToMany mapping using the foreign key.
Are you using JPA, or the TopLink API? JPA requires a mappedBy for the OneToMany, so this may be more difficult. You should be able to just add a JoinColumn on the OneToMany and make the column insertable/updateable=false.
For the attachment, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain it in your model, or use a VariableOneToOne mapping in TopLink (this will require the entities share a common interface).

One-to-many relationship within one bean
hello all,
Does S1 support a container managed one-to-many relationship to itself?
I used the verifer to verify my DD and the error is reported. (this prototype is migrated from weblogic6.1 and I use the S1 migration tool for the DD generation)

I beleive the migration tool missing the cmr-filed mapping for the oneClassAForManyClassA relation role.
but even if I add this mapping it still can't pass the verifiy.
So do I miss any thing or I can conclude S1 not support this one-to many self relation?
Any hint would be welcome.It does.
There is a known problem with parsing self-referenced relationship info - the one side (with <multiplicity> Many) must be the first in the <ejb-relation> entry.

Does anyone have a One to Many relationship for CMP working in 9.0.3 or 9.0.4? If so can you please send me the code at [email protected] I continue to get the following error:
com.evermind.server.rmi.OrionRemoteException: Transaction was rolled back: Database error: java.sql.SQLException: ORA-00904: invalid column name
Both beans work seperate but once I put the relationship in that is when I get the error.
Here is my relationship

Unable to read one-to-many relations using Hibernate
Hi,
I am trying with a very simple one-to-many relationship. When I am storing the objects, there are no problems. But when I am trying to read out the collection, it says invalid descriptor index. Please help.

Debug level Hibernate log excerpt:
Included in the above description.That's not the right mapping for the 1:m relationship in Hibernate.
First of all, I believe the recommendation is to have a separate .hbm.xml file for each class, so you should have one for Parent and Child.
Second, you'll find the proper syntax for a one-to-many relationship here:
http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html#tutorial-associations
See if those help.
The tutorial docs for Hibernate are quite good. I'd recommend going through them carefully.

ONE-to-MANY relationship between tables and forms in APEX
I recently started using APEX and I have run into an issue.
I have a ONE-TO-MANY relationship between two tables, A1 and A2, respectively.
A1:
A1_ID
Item
A2:
A2_ID
SubItem
A1_ID
I have 2 forms (lets call it F1 and F2) that I use to capture data for A1 and A2.
On F2, I have the following fields that are setup to capture data:
A2.A1_ID
**A1.Item (this is a drop down that is populated using a SELECT statement where the select uses A1.Item field)
A2.SubItem (user would enter SubItem)
Note: A2.A2_ID is populated using a SEQ
Everytime I pick **A1.Item on F2, is there a way to link to A1 table and display A1.A1_ID for every **A1.Item selected on F2?
If so, I want to store the value captured in F2 for the A1_ID field into A2 table to maintain my 1-to-MANY relationship.
If this will work, how do I go about implementing this solution?
Can someone help me?I think it sounds like you are asking for a Master-Detail form. Try that and see what you get.
