Oracle Toplink Jaxb mapping

Hi,
i try to use the developer Preview 3(10.1.3.0)workbench
and it work fine with simple java class (two xml files generation).
But with java servlet who use the same classes nothing
work i got some exception :
05/03/01 08:24:33 exceptionProvider oracle.toplink.ox.jaxb.JAXBContextFactory could not be instantiated: java.lang.NoSuchMethodError: oracle.toplink.publicinterface.Session oracle.toplink.tools.sessionmanagement.SessionManager.getSession(oracle.toplink.tools.sessionconfiguration.XMLSessionConfigLoader, java.lang.String, java.lang.ClassLoader, boolean, boolean)
I have also a strange message in the log window in jdev 9052 :

Thank you for your help.

The version of TopLink on your application server class path may be an older version of TopLink that does not contain the method mentioned in the stack trace.
If you are using OC4J the toplink.jar can be found in the following location:
<OC4J_HOME>\toplink\jlib\toplink.jar
The 10.1.3 DP3 version of OC4J can be found on OTN in the following location:

I found an error in ORACLE TOPLINK while adding table CUSTOMER, MOTHERBOARD and MEMORY from database to workbench. Any idea how to solve that error?
And other questions:
1. Does Toplink support inheritance and aggregation object table modelling? If it doesn't, what should I do?
2. Is there any example or tutorial using Toplink Foundation Library?
Thanks a lot.

What error do you get in the MW?
TopLink does support object-relational data-types, but the Mapping Workbench does not have support for object-relational data-types, so you may need to define your mappings through the TopLink Descriptor and Mapping Java code API. There is a section on object-relational data-type mappings in the TopLink User Guide.

Exception [TOPLINK-46] (OracleAS TopLink - 10g (9.0.4) (Build 031126))

Hi,
I am using TopLink for simple Department-Employee relation, i have my project xml configured, But i am facing the problem with following exception
Descriptor Exceptions:
Exception [TOPLINK-46] (OracleAS TopLink - 10g (9.0.4) (Build 031126)): oracle.toplink.exceptions.DescriptorException
Exception Description: There should be one non-read-only mapping defined for the primary key field [emp.empno].
Descriptor: Descriptor(com.oracle.mssql.emp.toplink.EmpTopLinkBean --> [DatabaseTable(emp)])
Runtime Exceptions:
What could be the reason?
Thanks
Madhu

My best guess would be that you have a 1:1 mapping from Employee to Department. This mapping represents part of the primary key.
Make sure that your 1:1 mapping is not configured as read-only. Another issue is that you may have set the relationship as target foreign key. This has the same effect as read-only and is not applicable in the 1:1 returning from a 1:M.

How can i using datasource in toplink's map file

In the TopLink map :
<toplink:login xsi:type="toplink:database-login">
<toplink:platform-class>oracle.toplink.platform.database.oracle.Oracle10Platform</toplink:platform-class>
<toplink:user-name>test</toplink:user-name> <toplink:password>C23487CFA591952D44310804F3D591CB</toplink:password>
<toplink:sequencing>
<toplink:default-sequence xsi:type="toplink:native-sequence">
<toplink:preallocation-size>1</toplink:preallocation-size>
</toplink:default-sequence>
</toplink:sequencing>
<toplink:driver-class>oracle.jdbc.driver.OracleDriver</toplink:driver-class>
<toplink:connection-url>jdbc:oracle:thin:@192.168.0.1:1521:testdb</toplink:connection-url>
<toplink:bind-all-parameters>true</toplink:bind-all-parameters>
</toplink:login>
How can i modify it using datasource?

The login information stored in the map file is good for direct connection and design time login information.
For your runtime login information I would use the sessions configuration (sessions.xml). It provides complete deployment configuration:
   <session>
      <name>my-session</name>
      
      <project-xml>META-INF/employee-basic.xml</project-xml>
      <session-type>
         <server-session/>
      </session-type>
      <login>
         <datasource>jdbc/TopLinkDS</datasource>
         <uses-external-connection-pool>true</uses-external-connection-pool>
         <uses-external-transaction-controller>true</uses-external-transaction-controller>
      </login>
      <external-transaction-controller-class>oracle.toplink.essentials.transaction.oc4j.Oc4jTransactionController</external-transaction-controller-class>

Help with: oracle.toplink.essentials.exceptions.ValidationException

hi guys,
I really need ur help with this.
I have a remote session bean that retrieves a list of books from the database using entity class and I call the session bean from a web service. The problem is that when i display the books in a jsp directly from the session bean everything works ok but the problem comes when I call the session bean via the web service than it throws this:
Exception Description: An attempt was made to traverse a relationship using indirection that had a null Session. This often occurs when an entity with an uninstantiated LAZY relationship is serialized and that lazy relationship is traversed after serialization. To avoid this issue, instantiate the LAZY relationship prior to serialization.

ConversionException in Toplink TIMESTAMP mapping

We have a column mapped in Toplink as java.sql.Timestamp. In order to make this work they've added a few lines to the toplink Oracle.xml file defining the timestamp type.
Inside JDeveloper this runs fine, however when run under Ant I get the following:

I've downloaded the newest JDBC drivers but the problem persists.
Anyone have some advice?

Oracle TopLink 10g Introductory Tutorial: No Table Reference available

Hi,
I'm trying to work through the Oracle TopLink 10g Introductory Tutorial (http://www.oracle.com/technology/products/ias/toplink/doc/10131/main/_tutorial/index.htm).
At the point 'Map the Java Classes: Create One-to-One Mappings' (http://www.oracle.com/technology/products/ias/toplink/doc/10131/main/_tutorial/index.htm) I'm not able to select a table reference because there is no one available.
As result i get the following message after generating 'Mapping Status Report':

Package example.model -> One of the descriptors in this package is incomplete.

Did I make a mistake or is there a wrong configuration? Please help.
I'm using:

Yes I did. But my database storage engine is set to MyISAM which don't support foreign keys. So this 'error' results from database configuration (Info: InnoDB do support foreign keys).
I'm wondering why the queries didn't throw any errors. So the foreign key/reference part was just skipped.
Thank you very much, rsapir.
PS:
How can I configure configure 'application side' references/associations? It is described in the TopLink Developers Guide on site 34-10 ... but I have no Add/New Buttons?

TOPLINK-6094: Mapping OntToMany (JPA)

Hello!
I'm learning how to use Java Persistence API and I'm getting an error which i don't know more what to do to solve it... :(

Guys,
Sorry my poor english, but I hope u can get the idea.
Thanks a lot!

Hello,
The original posting seems to have defined the relationship mappings joinColumns incorrectly. For instance, in the case of :
joinColumns=@JoinColumn(name="CD_USUAR", referencedColumnName="cdUsuar"),
The referencedColumnName should refer to the Database table's Column name, not the object's property name. So USUARIO_PROFISSAO's CD_USUAR column should reference USUARIO's CD_USUAR column, not "cdUsuar" which doesn't exist.
Check to see your mappings are set up correctly as well.
Best Regards,
Chris

Toplink JAXB - ClassCastException after redeploy in OC4J

Hi,
I'm experiencing an issue casting an unmarshalled object after the application is being redeployed in the container.
I'm trying to unmarshall an xml that I retrieve as a resource from the classloader (the xml is also in the jar)
The ClassCastException is being thrown at the point where I try to cast the unmarshalled object. A sysout on the unmarshalled object prints a classtype that I expect, so my first impression is that the cast fails due the ClassLoader used by the JAXBContext (?) So I've tried to create the JAXBContext with the ClassLoader parameter using the class' classloader directly and the contextClassLoader, both unsuccessfull.
The problem solves after I restart the OC4J container, but for convenience, I would like to solve this without having to restart, if possible.
Has anyone experienced this problem, or know a solution?
Thx!
Bert

Hello Bert,
This is a known issue and there is a patch that is available from Oracle Support. When you contact support please indicate whether you are using TopLink 10.1.3 or 10.1.3.1. Also you can refer Oracle Support to me and I can help them find the correct patch.

Oracle.toplink.essentials.exceptions.ValidationException

Hi,
In my EJB 3 application we added a Schema entity to our already existing Student entity.
I added the followning code in the student entity:
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(
nullable = true,
name = "SCHEMA_ID"
private Schema schema;
After adding the Schema enity I tried to compile and run the tests. I got the following toplink error message (roughly):
nternal Exception: Exception [TOPLINK-7250] (Oracle TopLink Essentials - 2.0 (Build b41-beta2 (03/30/2007))): oracle.toplink.essentials.exceptions.ValidationException
Exception Description: [class se.myapp.subsytem.alpha.Student] uses a non-entity [class se.myapp.subsytem.domain.Schema] as target entity in the relationship attribute [private e.myapp.subsytem.domain.Schema].
I found out that I had to change the persistence.xml but not why?
I would be very happy if someone could shed some light in this matter since I have no clue why I must put it in the persistence.xml
cheers,
//mike

You must either annotate every Entity with the @Entity annotation, or map it through the ORM.xml. All Entities must also define an @Id annotation.

Oracle.toplink.internal.helper.NonSynchronizedVector exception

I get following exception when invoking session bean from EJB client generated by JDev (EJB JPA project). Session bean returns the list of value objects created using TopLink Essentials based JPA native query. Does anybody know what is causing this exception and if there is a workaround?
java.lang.ClassCastException: oracle.toplink.internal.helper.NonSynchronizedVector
List<ProfileBasicVO> profiles = searchFacade.queryBasicProfilesByLastName( partialName );
I get exception at this point:
for( ProfileBasicVO profile: profiles ) {
System.out.println( "lastName = " + profile.getLastName() );
...

I changed the code to return List and I added mapping as a second parameter:
public List queryBasicProfilesByLastName(String partialName) {
Query basicProfileQuery =em.createNativeQuery( "findBasicProfilesByLastName", "BasicProfileResults" );
return basicProfileQuery.getResultList();
It fails with following exception:
Internal Exception: java.sql.SQLException: SQL string is not QueryError Code: 17128
and the query is defined as
<query>
select o.last_name as LAST_NAME,
o.first_name as FIRST_NAME,
o.middle_name as MIDDLE_NAME,
o.birth_date as BIRTH_DATE,
o.sex_code as SEX_CODE,
a.height_cm as HEIGHT_CM,
a.weight_kg as WEIGHT_KG,
o.PERSON_ID as PERSON_ID
from offenders o,
person_bookings b,
person_physical_attributes a
where o.PERSON_ID = b.PERSON_ID
and b.PERSON_BOOK_ID = a.PERSON_BOOK_ID
and o.last_name = 'POTTER'
</query>
Mapping is defined as:
<sql-result-set-mapping name="BasicProfileResults">
<entity-result entity-class="entities.Persons">
<field-result column="LAST_NAME" name="lastName"/>
<field-result column="FIRST_NAME" name="firstName"/>
<field-result column="MIDDLE_NAME" name="middleName"/>
<field-result column="BIRTH_DATE" name="birthDate"/>
<field-result column="SEX_CODE" name="sexCode"/>
<field-result column="PERSON_ID" name="personId"/>
</entity-result>
<entity-result entity-class="entities.PersonPhysicalAttributes">
<field-result column="HEIGHT_CM" name="heightCm"/>
<field-result column="WEIGHT_KG" name="weightKg"/>
</entity-result>
</sql-result-set-mapping>
I can execute the query manually without problem, i.e. it is valid query, but I still get exception

Oracle Toplink Version issue

Oracle Toplink Version
Hi all,
Can i know which version of toplink is stable?
currently i am using toplink v9.0.3 for our project.i found in the same forum that there is a bug(#2662726) in v9.0.3 related to improper setting of target foreign key and a suggestion to use v9.0.3.2 where bug had been fixed.
I am unable to find v9.0.3.2 download in oracle site.I found only the latest versions 9.0.4(10g product).I tried to install toplink 10g which is just an extraction of zip file,but i end up with the error "Windows cannot find '-Xmx128m' file" when i tried to start workbench.cmd
I found somewhere that there is a work-around for that bug - just reversing the feild names of addTargetForeignKeyFeildName() method.
I don't want to take risk.
please suggest me correct stable versions and place of downloads of both App.server and toplink
our Oracle Application server version is 9.0.3. if i am going to use the latest version of toplink,can it solve the issue mentioned above and also can it be compatible with app server version.
Thanks in advance.
Regards,
Karthick.

Hi doug,
Thanks for ur immediate response.
I had installed the latest patchset 9.0.3.6 and tried to generate project java source using workbench.
now the foreign key mapping problem is O.K. but i am having problems in the generated persistent classes code.
I am having certain feilds in a table in Oracle Database of type Number of size varying from 1 - 6. I used workbench to generate code for that table. In that i found that all attributes which has direct to feild mapping to a Number datatype in Database is of type Double(irrespective of size even for Number(1)).
I think it is a huge memory wastage having Double where an Integer or other types will do.
I would be very grateful if u help me in this regards.

How-to use custom data sources with OracleAS TopLink

Does anyone know if there is an updated version of this dcoument ?
I am having difficulties attempting to extend OracleAS TopLink to Support Custom Type Conversions.
Some of the links on this tutorial are broken
http://www.oracle.com/technology/products/ias/toplink/technical/tips/customconversion/index.html
Please help
Thanks,
John

Doug,
I may have been making a mountain out of a molehill.....
My problem while generating classes & descriptors was that Numbers from my Tables were being converted to BigDecimals.
I want these to be converted to Integers automatically as I am importing from approx 100 tables & don't want to update each mapping.
Is there a quick & easy way to achieve this ?
(I'm not being lazy & have spent 1/2 a day attempting to find this solution)
Many thanks,
John

Oracle TopLink Object-to-XML - issue JAXBException: Provider not found...

Env:
OS:XP
Java dev env: JDev 10.1.2 production
Toplink Workbench - 10g Developer Preview 3 (10.1.3.0) build 041116
I am attempting to use the toplink object to xml functionality through carefully following the tutorial titled Oracle TopLink Object-to-XML on OTN (link: http://www.oracle.com/technology/products/ias/toplink/preview/10.1.3dp3/howto/ox/index.htm)
The first 11 steps are nice and clear and very easy to follow. However, when I hit 12 I run into problems. I believe I have done all I am required to do.
My demo test code falls over on the attempting to create the JAXB context:
JAXBContext jaxbContext = JAXBContext.newInstance("examples.ox.model");
The exception I get is:
javax.xml.bind.JAXBException: Provider oracle.toplink.ox.jaxb.JAXBContextFactory not found
- with linked exception:
[java.lang.ClassNotFoundException: oracle.toplink.ox.jaxb.JAXBContextFactory ]
The code is capable of loading the jaxb.properties file, and has toplink.jar in the classpath. I am able to create a is located JAXBContextFactory prior to calling the new instance logic, illustrating that the class is in the classpath.
Using google I have seen it mentioned that the newInstance call could be making use of a different JVM to the Application (https://jaxb.dev.java.net/faq/#classloader) hence may not be able to pick up the JAXBContextFactory class. I have attempted to follow their advice of passing in a class loader - but this makes no difference.
I.E. JAXBContext jaxbContext = JAXBContext.newInstance("examples.ox.model", this.getClass().getClassLoader());
Does anyone recognise this issue and have a solution.
Here is my code:
try
File file = new File("D:\\Toplink\\demo\\Customer-data.xml");
JAXBContext jaxbContext = JAXBContext.newInstance("examples.ox.model);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) unmarshaller.unmarshal(file);
System.out.println(" customer.getFirstName() : "+customer.getFirstName());
catch(Exception e)
System.out.println("Error: "+ e.toString());
As mentioned earlier it falls over on JAXBContext.newInstance("examples.ox.model);
cheers
Nick

Hi Blaise,
thanks for your response.
My session.xml file is located:
D:\Toplink\demo\classes\session.xml
And contains:
<?xml version = '1.0' encoding = 'UTF-8'?>
<toplink-sessions version="10g Developer Preview 3 (10.1.3.0 )" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<session xsi:type="database-session">
<name>examples.ox.model</name>
<event-listener-classes/>
<primary-project xsi:type="xml">D:/Toplink/demo/classes/CustomerProject.xml</primary-project>
<login xsi:type="xml-login"/>
</session>
</toplink-sessions>
My classpath references only jars downloaded with the links on the How To tutorial titled Oracle TopLink Object-to-XML on OTN (link: http://www.oracle.com/technology/products/ias/toplink/preview/10.1.3dp3/howto/ox/index.htm)
This is the JDev output indicating the classpath and error:
D:\Jdev1013Preview\jdk\bin\javaw.exe -ojvm -classpath D:\Toplink\demo\classes;D:\Toplink\lib\xml.jar;D:\Toplink\lib\xmlparserv2.jar;D:\Toplink\toplink\jlib\tljaxb.jar;D:\Toplink\toplink\jlib\toplink.jar examples.ox.model.RunDemo
Error: javax.xml.bind.JAXBException: Provider oracle.toplink.ox.jaxb.JAXBContextFactory not found
- with linked exception:
[java.lang.ClassNotFoundException: oracle.toplink.ox.jaxb.JAXBContextFactory
Process exited with exit code 0.
Any more suggestions?
In the meantime I will go through the information on the link that you have sent and see if I can get anyfurther.
Thanks
Nick
