OC4J 9.0.4 / EJB-QL / cmr-field

Hi,
I'm using the OC4J 9.0.4 developer preview and am trying to construct some EJB-QL of the following form:
select object(A) from MANYTABLE A, IN (A.cmr_field_to_ONETABLE) AS B
where A.field = ?1 and B.pk_field = ?2
where ONETABLE has a 1:m bidirectional relationship with MANYTABLE. The cmr-field entry for cmr_field_to_ONETABLE is present in the ejb-jar.xml.
In the underlying database tables, the cmr_field_to_ONETABLE in A is a foreign key to pk_field of B.
When I attempt to deploy the application, OC4J screams about an "Error translating EJBQL" saying that:
Was expecting one of:
"AbstractSchemaName" ...
"IN" "(" "IdentificationVar" "." "SingleValuedCmrField" "." ...
"IN" "(" "IdentificationVar" "." "CollectionValuedCmrField" ...
This doesn't make sense to me. As far as I can see, the EJB-QL is correct.
Suggestions?
regards
George

Cmr field and ejbgen

How do i define a cmr-field through ejbgen annotations in weblogic?
I have defined the relation as
* @ejbgen:relation
* multiplicity = one
* name = EntityCanHaveMultipleJournals
* role-name = EntityHasJournals
* target-ejb = FTEntityEJB
* @ejbgen:ejb-local-ref
* home = ft.infosys.journal.FTJournalHome
* local = ft.infosys.journal.FTJournalLocal
* jndi-name = FTJournal
* name = Journal
* type = Entity
And the accessor/mutator as:
* @ejbgen:cmr-field
* @ejbgen:local-method transaction-attribute = NotSupported
abstract public Collection getJournals();
* @ejbgen:local-method transaction-attribute = Required
abstract public void setJournals(Collection val);
Though this does not give any error on executing ejbgen,and the local and home interfaces are fine;the CMR field is not appearing in the relations tag in ejb-jar.xml.
So i have to add the following manually in ejb-relations:
<cmr-field>
<cmr-field-name>journals</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
Why so?

cmr field which is "category" in ur mapping , u can't use as cmp field in abstract schema mapping. just remove category from cmp field . and every thing is fine

EJB-QL with self referencing cmr-field in path identifier fails

I have a simple application . Only one bean and one relationship. The relationship is a (0..1)-(0..1) for the same bean (self referencing).
I have a finder method defined with ejb-ql that tries to access the field of one of the cmr fields of the relationship.
class1Bean is the abstract schema for my bean, and subclass1 is the cmr-field name.
SELECT OBJECT(obj) FROM class1Bean obj WHERE obj.subclass1.id LIKE ?1
Here is the error message when trying to deploy:
Bean: Class1
Method: java.util.Collection findBySubclass1(java.lang.String)
EJBQL: SELECT OBJECT(obj) FROM class1Bean obj WHERE obj.subclass1.id LIKE ?1
Error: JDO75100: Fatal internal error: JDO75341: Missing field meta data for field 'subclass1' of 'Class1'
This same code deploys fine on JBoss 4.0, and should be legal ejb-ql. Is this a known issue with Sun JSAS?

Sounds like a problem with the bean metadata. Please check the entity mapping defined in sun-cmp-mappings.xml. Also make sure field sublass1 is defined as CMR everywhere.

Javax.ejb.EJBException: Attempt to access a collection valued cmr-field

I have 2 local CMP project and defect
i have a method getDefectList in ProjectBean. This method returns a collection of defect object.The relationship of Defect and Project is defined in ejb-jar where project can contain many defects.
when i try to access this method in a session bean it gives me the error
"javax.ejb.EJBException: Attempt to access a collection valued cmr-field outside the scope of a transaction."
Please let me know the solution.

After further research, it looks like CMR fields can only use three options for the trans-attribute: Mandatory, Required, or RequiresNew
<container-transaction>
<description>Transaction attributes</description>
<method>
<ejb-name>strong.customer</ejb-name>
<method-name>*</method-name>
</method>
<trans-attribute>Mandatory</trans-attribute>
</container-transaction>
thus I believe that you will have to begin a transaction before executing your method.

Orion-ejb-jar: cmp-field-mapping specs REMOTE home

In the tech. preview documentation, in the EJB dev. guide, and in the section which details the orion-ejb-jar, I noticed something odd about the "cmp-field-mapping" element. It has an attribute called "ejb-reference-home", which is supposed to be "the JNDI location of the fields remote EJB-home if the field is an entity EJBObject or EJBHome".
I would assume this would only be set if this field was specified as a CMR field in the ejb-jar.xml file.
The odd thing is, it specifies the REMOTE home, not the LOCAL home. Is this just a typo?

I believe that it is not JDeveloper issue but OC4J one. It does not pick up new orion-ejb-jar.xml if you re-deploy bean(s). It should deploy your orion-ejb-jar.xml when you're deploying yor application for the first time (so there is not orion-ejb-jar.xml in deployments directory). If you want OC4J to pick changes up remove orion-ejb-jar.xml from $OC4J_HOME/application-deployments/<application>/<Bean>.jar/ and then deploy it either manually or with JDeveloper. I hope it will help.

JDeveloper / OC4J rewriting my orion-ejb-jar.xml

Hi All.
Im having a play around with OC4J and CMP entity beans and struts at the moment learning some stuff for a new job, so ive started to write a little test app to get used to things.
Ive created a CMP entity - CustomerEntityEJB, manually defined the tables etc wrote and built it using JDeveloper 10.
Ive created all the necessary classes and descriptors in JDeveloper and the bean compiles and deploys fine, however no matter what i do, the table attribute of the <entity-deployment> elemnt is ALWAYS removed from the orion-ejb-jar.xml file before its deployed and i have no idea why.
Here are some snippets form the xml config files im using....
ejb-jar.xml :

As you can see, the orion-ejb-jar.xml that been deployed on the server has had extra attributes defined in it (like concrete-bean-class) which makessense - its adding in the bits i didnt to get th bean to deploy - however the table attribue is just removed, meaning my bean cant find the table - hence my app not working.
i just dont know how to stop this and would be extremely grateful if someone could give me a clue how to get my bean up and working properly as this is driving me insane.
Thanks in advance..
Gareth.

sorted - the <persistence-manager name="toplink"/> element was automatically generated by JDeveloper and put in my orion-ejb-jar.xml appears to be un necessary and seemed to be breaking eveything - as soon as i removed it, the bean seemed to deploy ok and pick up the table name =]
as a bit of an aside does anyone know why it was automatically put there in the first place if it breaks things?

A cmr-field and a cmp-field on the bean are using the same name. The names

Hi:
I am using weblogic 8.1 and MyEclipse 5.1.1. I am deploying my ear application through MyEclipse 5.1.1 as an ear file.
When I ran the following EJB QL:
SELECT OBJECT(p) FROM Product p.category = ?1
I get the following error:
n relation Category-Product, a cmr-field and a cmp-field on the bean are using the same name. The names of cmr and cmp fields must be unique.
It is basically complaining that I have a field
<cmr-field>
                         <cmr-field-name>category</cmr-field-name>
                    </cmr-field>
in my ejb-jar.xml and also the same category in the
<cmp-field><field-name>category</field-name></cmp-field>
field. The problem is that if I changed the value of the cmr-field, I have to add a get and set in my productLocal.java and when you do that you have to do the same in the ejb-jar.xml.

What do I needed to do to fix this problem.
Any hint or help would be greatly appreciated!!!
Yours,
Frustrated

cmr field which is "category" in ur mapping , u can't use as cmp field in abstract schema mapping. just remove category from cmp field . and every thing is fine

All cmp-fields that double as cmr-fields must have an object type??

Greetings,
I'm deploying an application in weblogic 8.1sp2 that worked fine in
jboss 3.2. The error is:
Exception:weblogic.management.ApplicationException: prepare failed for
ServiceEJB.jar Module: ServiceEJB.jar Error: Exception preparing module:
EJBModule(ServiceEJB.jar,status=NEW) Unable to deploy EJB:
ServiceEJB.jar from ServiceEJB.jar: [EJB:011017]Error while reading
'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was: In relationship
'primitive_TO_primitive_param', role
'primitive_param_BELONGS_TO_primitive', a cmp-field used to implement
this relationship has a primitive type. All cmp-fields that double as
cmr-fields must have an object type. . at
weblogic.ejb20.ejbc.EJBCompiler.doCompile(EJBCompiler.java:255) at
Does it means that I should cmp field from "int" type to "Integer"
object??? If true, I really don't know why the requirement since in
jboss worked just fine. But do you confirm it?
regards,
Pedro Salazar

I believe there is a requirement that any field used as a primary or
foreign key must be an object and implement hashCode/equals.
I'd post in weblogic.developer.interest.ejb.cmp if you want more
information.

Hello,
I have two ejbs, one called EstablishmentEJB and another called VisitorCommentsEJB. The relationship is of one EstablishmentEJB instance to many VisitorCommentsEJB instances.
Here are the definitions for the tables:
CREATE TABLE establishments (
DB_ESTABLISHMENT_ID int(11) NOT NULL default '0',
DB_POSTCODE varchar(100) NOT NULL default '',
DB_ESTABLISHMENT_NAME varchar(255) NOT NULL default '',
PRIMARY KEY (DB_ESTABLISHMENT_ID)
) TYPE=InnoDB;
CREATE TABLE visitors_comments (
DB_VISITOR_COMMENT_ID int(11) NOT NULL auto_increment,
DB_ESTABLISHMENT_ID int(11) NOT NULL default '0',
DB_COMMENT varchar(255) NOT NULL default '',
PRIMARY KEY (DB_VISITOR_COMMENT_ID)

Thanks all for replying,
The error occurs when I run the client and not at deploy time. Here is the client code:
     public void addComment(Integer primaryKey, String comment) {
          System.out.println("primaryKey------>" + primaryKey);
          try {
               PGEstablishmentLocalHome establishmentHome = (PGEstablishmentLocalHome) PGServiceLocator.getInstance().getLocalHome("PGEstablishmentHome_L");
               PGEstablishmentLocal establishmentLocal = establishmentHome.findByPrimaryKey(primaryKey);
               establishmentLocal.addComment(primaryKey,comment);
          } catch (PGServiceLocatorException e) {
               e.printStackTrace();
          } catch (FinderException e) {
               e.printStackTrace();
u haven't defined the PK entry in the Establishment EJB Bean in DDYes look in the standard DD.
What's more I need both DD as I would with most ejb containers.
The field DB_ESTABLISHMENT_ID is required and I cannot set it to NULL.
Any other help greatly appreciated.

Finder method to retrieve CMR field?

Hello all!
I have two entity EJBs - one named "Property" and another named "Merchandise".
Property has a one-to-many relationship to Merchandise, and Merchandise is a CMR
field (named "merchandise") in Property. Now I would like to write a finder method
for Property to retrieve the CMR field (Merchandise references). The finder method
is called "findDVD()". The ejb-ql is below:
SELECT DISTINCT OBJECT(merch) FROM Property AS p, IN(p.merchandise) AS merch
WHERE merch.starsMasterTitleId = ?1
AND merch.productTypeCode = 'VIDEO'
AND merch.format = 'DVD'
AND merch.active = 'Y'
AND merch.approved = 'Y'
AND merch.purchaseable = 'Y'
However, I can't seem to get this method to work. Weblogic's EJBC keeps complaining
that the returned collection MUST be of the method owner type - in other words,
I can't return Merchandise references, only Property references.
What am I doing wrong? Is this a limitation in CMR that I didn't know about? Please
help!
I am using WLS 6.1 with SP 1.
Thanks so much!

If you are using ejb2.0 you can do this using a home method and select
method instead of a finder. Finders are limited to returning objects of the
type of ejb they belong to while select methods are not. Select methods
cannot be invoked directly by the clients so you need a home method to wrap
them.

AND merch.productTypeCode = 'VIDEO'
AND merch.format = 'DVD'
AND merch.active = 'Y'
AND merch.approved = 'Y'
AND merch.purchaseable = 'Y'
However, I can't seem to get this method to work. Weblogic's EJBC keepscomplaining
that the returned collection MUST be of the method owner type - in otherwords,
I can't return Merchandise references, only Property references.
What am I doing wrong? Is this a limitation in CMR that I didn't knowabout? Please
help!
I am using WLS 6.1 with SP 1.
Thanks so much!

IllegalStateException for cmr-fields due to diff txns

Hi,
I am using cmp entity beans on WebLogic Server 7. Assume bean 'A' to bean 'B' is
1:M
I get the following exception while trying to create bean B -
<Exception in MyClass.createB(): javax.ejb.EJBException: EJB Exception:: java.lang.IllegalStateException:
Attempted to access the collection valued cmr-field, 'b', for bean, 'A', in a transaction
that is different than the transaction in which the collection was materialized.
All access to the collection must be performed during the transaction in which the
collection was initially retrieved.
I upgraded from 6.1 sp2 to 7 and got this exception. I never got it in wls 6.1 sp2.
Since my beans are cmp, the container handles all transactions and I have specified
<trans-attribute>Required</trans-attribute> in ejb-jar.xml.
How can I ensure that the container uses the same txn for accessing all cmr fields?
I will appreciate if anyone can point me in the right direction.
Thanks!

I figured out the problem. The caller that calls methods on the entity bean interfaces
has to wrap the calls inside a transaction.

Using CMR field as Primary Key in Entity Bean

Hi, all!
Can somebody tell me, is it possible to use CMR field as Primary Key field in Entity Bean?
Thanks

WebLogic Server supports mapping a cmr field to the primary key.

EJB Update one field

Hi,
Up until now, most of my forms in jsf have had all the fields in the ejb. So when I did mergeEntity all the fields where updated with the correct data. Now I have a form that has just the ID of the ejb and one field. Now when I do mergeEntity all the other fields are set to null. Shouldn't mergeEntity just update the field I am setting? What do I need to do to update just one field in the ejb without bringing all the other fields in or is there an easy why to do that?
Thanks for you help. Any examples would be great!

You're not supposed to put ## around it. That makes
Coldfusion look for a variable named "originated" inside a
structure named "affiliate", which obviously isn't what you want to
do.
In my query, I didn't have any hashes around field2.
Change your query to:
<CFQUERY datasource="#application.dsn#">
UPDATE affiliate
SET last_contacted = originated
</CFQUERY>
