Toplink mapping generator hangs...

I am using the preview 1013 Jdev version with a MySQL DB. The connection to the DB works fine.
When I try to generate the toplink mapping for a single small test table, the "generating offline database objects" progress bar just keeps going back and forth and the process hangs and I have to kill Jdev from the Task Manager.
Is this a known bug in the preview or am I doing something wrong?
Thanks much for any insight.
David Littman

David,
This is a known issue (bug 4373381) and will be addressed in the production version
Thanks

Point Toplink map to exactly same schema but differnt schema

Hi all,
We want to point our Toplink mapping which is generated using a test schema to "real data schema" which has exact same structure.
Is it possible to do it.?
May be it will make more sense if I say, we want to edit WSDL of Database adapter and expect same adapter to go to the new schema connection (which we put there after editing the wsdl).
I hope I explained and its the right place to ask the question.
thanks in advnace

Hi there,
the best place to ask DBAdapter questions is probably Integration - Adapters.
Integration - Adapters
If in design time you create your database connection with one username but import tables belonging to a second username, then the toplink-mappings.xml will contain explicit schema references. This can cause troubles switching from development to production.
At this point best thing you can do is edit toplink_mappings.xml and search and replace i.e. "SCOTT." with "". That will reduce any qualified table references in that file with unqualified ones, i.e. SCOTT.EMP -> EMP.
If your (subsequent) problem is at runtime logging in as one user but wanting to interact with tables belonging to a second user, then in application-deployments/default/DbAdapter/oc4j-ra.xml, and in connectors/DbAdapter/DbAdapter/META-INF/ra.xml you could configure the property tableQualifier="<secondUserName>". However you will still need to make sure there are no explicit schema references in toplink_mappings.xml before this advanced 'tableQualifier' setting can take effect. This 'tableQualifier' setting was what Doug was referring to.
Thanks

Multiple Toplink Mapping files

Hi All,
I have 8 modules in my project, I would like to maintain separate toplink mapping file and persistence-config.xml file for each module.
Ex: in struts we can have separate struts-config.xml file for each module like struts-admin-config.xml, struts-moderator-config.xml, struts-dashboard-config.xml files and we will configure those information in web.xml file for Actionservlet input params.
Is it possible to have multiple toplink mapping files and persistence configuration files for each module in a project.
Thanks & Regards,
B.V.Suresh Babu.

Thanks a lot for your direction!
I am using xtreme framework alongwith Toplink. I use codegen tool to generate extreme BOM (business object model) classes. I an unable to introduce my logic as you suggested to use Direct Mapping.
I am not able to find more details and/or complete example to use any of your suggested approach. Please do send me any stuff you can send for the same.

Vulnerability - Oracle toplink mapping workbench password algorithm

Could someone from Oracle post security contact info. This is regarding a possible vulnerability in TopLink referred to in this posting:
http://marc.theaimsgroup.com/?l=bugtraq&m=107531028325112&w=2
I would like to know Oracle's response to this item before I publish a report to our clients.
Thanks,
Mark Hoffman

It has come to our attention that a 3rd party has published the algorithm used to obfuscate a database password stored in the runtime configuration file (project.xml or java source file) generated by the TopLink Mapping Workbench version 9.0.3.
This database password is NOT used when TopLink is using an application servers database connection pool and this issue does not apply. In this case TopLink uses a specified data source name and the application server manages the database password.
For those not using the app server connection pool, the obfuscation is not meant to offer encryption protection for the password stored in the file. It is a mechanism meant to make the password in the file unreadable to the naked eye. It is not a replacement for proper file permission and access control to protect the file.
It is an optional convenience feature that customers have requested as they have found it to be useful during development and internal testing. The only way the password is saved in the file is if the option that is explicitly marked Save Password (Unencrypted) is used.
For encrypted security protection using technology such as Java Cryptography Extension (JCE), the unencrypted password can be set using APIs provided in the TopLink runtime libraries. A code example follows:
boolean shouldLoginSession = false;
DatabaseSession session = null;
session = (DatabaseSession)SessionManager.getManager().getSession("MySessionName", shouldLoginSession);
String password = //retrieve the password as an unencrypted string from somewhere
session.getLogin().setPassword(password); //note this assumes that the user is already set in the project
session.login();
Guidelines:
1.     If you are using the application servers database connection pool, this issue does not apply. TopLink simply specifies a data source name and the application server manages, stores and encrypts the password.
2.     If you are not using the application servers database connection pool, use the optional Mapping Workbench feature to store the password in the project.xml or java source file for development or internal testing purposes only if there is proper file permission and access control to protect the file.
3.     For deployment or unsecured development environments utilize the TopLink APIs provided that allow secure password encryption technology to be used.
This issue only applies to version 9.0.3 and prior; in 9.0.4 the TopLink Mapping Workbench uses JCE to encrypt the file.

TopLink Map issue

Hi all
i m very new to ADF ...
while creating one toplink i selected emp as my table .it asks for toplinkmap in the wizard so i created new and it took some value by default.
now when i rebuild this project it gives following error
TopLink Map 'tlMap1' -> One of the packages is incomplete.
Package dataprj -> One of the descriptors in this package is incomplete.
Descriptor Emp -> No primary keys specified in APPS.EMP table.
End TopLink Map 'tlMap1'
pls help me out to fix this issue.

hi user530923
Maybe you should look for the "EMP" node in the "Offline Database Sources" node of your JDeveloper project (using the Applications Navigator in JDeveloper).
If you right-click that "EMP" node, you can select "Properties...". The Edit Offline Table dialog should show. Select "Primary Key Information" on the left. Has a primary key been defined?
You could also check "Decriptor Info" tab for your "Emp" descriptor. Select "Application Sources" > "TopLink" > "tlMap1" in your JDeveloper project, in the Structure pane double-click the "Emp" descriptor and check "Primary Keys" on the "Decriptor Info" tab.

Hi Sree,
If you could email me a copy of the whole mapping workbench project, I can probably fix this issue for you.

Reverse engineer Toplink mapping to a ERM diagram

Hi,
We have a Toplink mapping for our application, the problem is that in the database no foreign keys relationship are defined, thus the relations
are only in our Toplink model and not in our database. Id like to create a ERM model with for instance the new "Oracle SQL Developer Data Modeler".
Is there a way do reverse engineer a Toplink model to a ERM diagram?
Regards Jonas.

Hi Jonas,
unfortunately there is no support for Toplink.

Every table need primary key in toplink mapping to fetch the data

Hi everyone,
we are working on toplink mapping , it neccessary every table needs primary key. if yes, gave me example.

Hi everyone,
Alterations in database will not be automatically reflected in toplink so, there is any alternative
with regards

TopLink map a field which name in low case

I used Oracle ADF to modeling my database table. My table name and all filed names are in low cases. I used TopLink Create Java Objects from Tables wizard to crate Java objects from my table, and created map. In the TopLink mapping, the query keys are in low cases. But when my session bean execute the named query, the query statement from executeQuery doesn't put double quotes around the filed name and table name. The query statement like: select name from space. So it will cause error like "java.sql.SQLException: ORA-00942: table or view does not exist". The query statement should like:
select "name" from "space";
Can anyone tell me where to edit the mapping or customize code to put double quotes around field name and table name?

I'm not sure if the JDev UI has an option to output table and field names with quotes. You could use a SessionCustomizer in your TopLink sessions.xml file to iterate over the Session's descriptors and change each of their table and field names to include the " character.
In general you will make you life much easier if you just create the tables and field using normal upper case or case insensitive names.
It would be nice to have an easier way to quote all table and field names, please feel free to log this issues on EclipseLink Bugzilla.

Detailed information would be greatly appreciated.
Thanks,

Todd,
Follow these steps.
1. First map your CustomerMaster descriptor either manually or by using the automap wizard.
2. Specify the primary key(s) (it does not have to be on the database) by checking appropriate fields listed under the "Primary Keys:" in "Descriptor Info" tab.
3. Run the mapping status report to make sure you have no errors in mapping.
Hope this helps.

Toplink-Map disappeared in Applications Navigator

Hi,
I can no longer find the toplinkmap in the applications navigator. This presumably happened when i changed the database connection in the sessions.xml from a native connection to a j2ee-datasource. The *.mwp-File is physically still there, 'Search in Files' also finds occurences of strings in it, but when double-clicking the according resultitem only a pane with a close-icon shows up. So for some reason jDeveloper ignores the presence of the toplink map. The application itself works fine, but i can no longer inspect or change the toplink map, e.g. can not add/remove queries to/from it.
Any idea someone? Thanks,
Magnus

I fixed it myself by comparing the content of the jpr-File with that one of a 'working' Project.

Toplink mapping for one-to-many object inheritance

Hi
I currently have a Person object, extended by two specialist classes, PremisesLicenceHolder and PersonalLicenceHolder. I have mapped this in Toplink and it works fine saving a person into the specialist tables using the primary key person_id.
However, a single Person may be extended any number of times by either one or both of the two specialist types. So, a Person may be a PremisesLicenceHolder many times over for different premises and licences, and also a PersonalLicenceHolder several times over.
Is it possible to map this object model in Toplink avoiding duplicate person_id primary keys in the specialist tables?
Thanks

Hi,
I am happy that my object model fits the problem domain. The Person and Organisation objects contain base information and have the primary keys person_id and organisation_id. It is important that there is no duplication of person and organisation records, no matter how many times they are saved in different roles.
There are two types of licenceholder in the problem domain, and the ILicenceHolder interface defines information and methods that are common to both. The PersonalLicenceHolder object represents one of these types of licenceholder, and is always a person, so this class extends Person and implements ILicenceHolder.
The additional information and methods that are required by the second type of licenceholder are defined in the interface IPremisesLicenceHolder, which extends ILicenceHolder. Premises licence holders can either be people or organisations, so I have two objects to represent these - PremisesLicenceHolderPerson which implements IPremisesLicenceHolder and extends Person, and PremisesLicenceHolderOrganisation which implements IPremisesLicenceHolder and extends Organisation.
The model is further complicated by the fact that any single Person may be both a PersonalLicenceHolder and a PremisesLicenceHolderPerson, and may be so several times over. In this case, the same basic Person information needs to be linked to several different sets of licenceholder information. In the same way, any single Organisation may be a PremisesLicenceHolderOrganisation several times over.
Sorry this is complicated!
My initial idea for the schemas is to have Person and Organisation tables containing the basic information with the primary keys person_id and organisation_id. The Person table would have a one-to-many relationship with both the PersonalLicenceHolder table (pk: personalLicenceHolder_id, fk: person_id), and the PremisesLicenceHolderPerson table (pk: premisesLicenceHolderPerson_id, fk: person_id). There would also be a one-to-many relationship between the Organisation table and the PremisesLicenceHolderOrganisation table (pk: premisesLicenceHolderOrganisation_id, fk: organisation_id).
I am flexible as to the design of my schema though, as I am happy to adopt any that will facilitate the Toplink Mapping.
Thanks for your help with this.

N-m mapping generates blobs in ref-table

Why generates the schematool blobs in the reference-table of a n-m mapping?
I want to map an existing schema and this isn't possible with blobs. I
expected a table with the primary-keys of each class.

Kodo fully supports n-m and m-m mappings. If you post your .jdo files and
describe your schema somehow we can probably help you find out where the
problem lies.Hello,
here I send you a short and useless example which contains
my two problems:
- n-m mapping generates blobs in ref-table
- multi-table inheritance mapping
This are my classes:
Class Person
String firstname
String lastname
Class Employee extends Person
long personalNumber
Collection memberOf ( TYPE Project )
Class Project
String projectname
Collection members ( TYPE Employee )

Kodo generates this db-schema:

Table db_project

**** the mapping should use the primary keys, no blobs ****
Column EMPLOYEE_FIRSTNAME ( Type varchar(50) ) <ForeignKey>
Column EMPLOYEE_LASTNAME ( Type varchar(50) ) <ForeignKey>

JDev 9.0.5.2 Error When Opening TopLink Mapping Project

I was in the middle of mapping my classes and realized that I needed some more attributes. So I added the attributes to my classes, closed the IDE (since this is generally the only way to get the TopLink Mapping Project to notice the changes), and now, when I reopen the IDE, I get the following:

John,
You mentioned "I closed the IDE so that the TopLink project would pick up the changes..."
1. We need to find out why you needed to close the IDE? Was TopLink mapping editor not picking up your changes?
2. I am sure you did not modified .java outside of Jdev, but in case if you did, let me know.
3. After removing a superclass attribute, did you save all changes?
4. We tried various combinations, but were unable to reproduce the project reopen issue that you mentioned was fixed by changing the ClassDescriptor.xml. It would be extremely helpful if you could either send us (anuj dot k dot jain at oracle dot com) a project that can reproduce this issue, or outline the exact steps.

StackOverflowError after adding a table to a TopLink Map

Hello,
I am really puzzled by the next problem. After adding a table (Customer) to an existing TopLink Map, I get the same kind of error for every query in the project that I use.
ERROR J2EE EJB8006 [CustomerToplinkTestPublicFacade:public java.util.List com.companyname.toplinktest.model.CustomerToplinkTestPublicFacadeBean.findCustomersByCompany(java.lang.String,java.lang.String)] exception occurred during method invocation: javax.ejb.EJBException: java.lang.StackOverflowError
I get this with every page and every query, just change the name findCustomersByCompany to the name of the named query. Otherwise all pages seems to have the correct behaviour Removing the Customer-table from the application solved all problems, and they reoccurred after adding the table again.
I have no clue why this happens, the only thing that might be useful is the fact that the Customer-table is also a part of a database view which I already use.
but why would that cause errors on queries it has absolutely no relation to
Kind regards,
Nemata

hello,
another update on my testcases. I have used the following procedure to narrow down the source of the problem.
First I create one or more TopLink pojo's based on my database tables and views, add them to a session bean and create the data controls. I'm always working with the default named queries (selectAll).
Then I create a .jspx file, drag and drop a data control from the data control palette to create an ADF table with the defaults...
and run... with one of two outcomes.
I either get all the data from the table (correct) or I get a message "no rows yet" and an error message in the log window "2006-05-04 12:37:40.214 ERROR J2EE EJB8006 [testCustomerSession:public java.util.List model.testCustomerSessionBean.findAllCompany()] exception occurred during method invocation: javax.ejb.EJBException: java.lang.StackOverflowError"
This is an overview of the testing I have done:
Objects created | ADF table | Error
Customer | Customer | Yes
Company | Company | No
Customer and Company | Company | Yes
Company and ViewOfCustomer | Company | No
Company and ViewOfCustomer | ViewOfCustomer | No
Company and Person | Company | No
ViewOfCustomer is a database view with the same data as the Customer. So the table Customer seems to cause the problem.
Does anybody have an idea why a database table might cause such distinct problems ?
Kind regards,
Nemata
