Using TopLink Workbench in Jdeveloper HELP!!!!!

HI! I want to know how can I use TopLink Workbench in JDeveloper to configure java classes???
Please Help!!!
Best Regards

JDeveloper has built in TopLink design time - so you don't need the external TopLink Workbench.
Try following one of the TopLink Tutorials here:
http://www.oracle.com/technology/obe/obe1013jdev/10131/10131_adftoplink/master-detail-edit_page_adf_toplink.htm
and

Toplink workbench in JDeveloper

Hi All,
I'm working with jdeveloper and I'm using toplink.
My problem is I'm not getting the toplink work bench

Hi,
Please, could you be more precise?
What is your Jdeveloper version ?
1 - If you want use Toplink in a web application, you can use the web [jsf,ejb,toplink] application template.
Perhaps, this link could help you :
http://www.oracle.com/technology/obe/obe1013jdev/10131/10131_adftoplink/master-detail-edit_page_adf_toplink.htm#t2s1
If you want just use toplink, you can create a empty project and add the toplink technology in "Project properties" > "Technology scope"

Calling an Oracle stored procedure using Toplink API - Please help

Hi,
We are evaluating Toplink as a possible data access layer in large service-oriented application. The ability to call db stored procedures from within business object layer is crucial for our architechture.
I am trying to follow toplink application developer's guide examples on how to call stored procedures using toplink.
I have the folling java code:
call.setProcedureName("PR_ROMAN_TEST");
call.addNamedArgument("IN_PARAM");
call.addNamedOutputArgument("OUT_PARAM");
ValueReadQuery query = new ValueReadQuery();
query.setCall(call);
query.addArgument("IN_PARAM");
Vector params = new Vector();
params.addElement(new Integer(5));
Number result = (Number) session.executeQuery(query, params);
This generates the following SQL statement:
BEGIN PR_ROMAN_TEST(IN_PARAM=>5, OUT_PARAM=>?); END;
An attempt to execute it causes a
java.sql.SQLException: Invalid column index.
As I understand it, this exception is thrown because of the "?" in place of the out-parameter value holder.
The SQL statement that I would want toplink to generate and execute should look like:
DECLARE result number; BEGIN PR_ROMAN_TEST(IN_PARAM=>5, OUT_PARAM=>result); END;
, but how do I achieve it and how do I capture the return value, all using toplink api?
Please help
Thank you in advance,

Help with useing toplink please..

Hello
I am writing J2EE apps that will run on a 10g app server. I thought that toplink was what I should be using to do my model layer. But there are several simple things I can't find out how to do. Things like make a LOV, how do I set a where clause and restrict what the end user is looking at?
Should I be using the ADF stuff instead? I was under the impression TopLink was the future direction at oracle so thats why I picked it. I have worked all the toplink tutorials I found. I can create mappings and all that. Setting it up isn't the problem, using it once I have it set up thats what I need to figure out. Can anyone point me in the direction of some tutorials or examples on how to use toplink? (especially in j2ee apps).
Thanks
troy

Troy,
TopLink is a core piece of Oracle's enterprise Java strategy. We are dedicated to standardization of ORM persistence through EJB 3.0 and TopLink is our implementation and the basis of Sun's reference implementation. Additionally, the use of TopLink is not mutually exclusive to using ADF. Within ADF you can use a variety of persistence technologies including TopLink.
Here is a sample workshop on building applications with TopLink in ADF: http://www.oracle.com/technology/obe/obe9051jdev/ide1012/adfworkshop/buildingadfapplicationsworkshop.htm
In order to filter or restrict results coming back from the database you need to make use of queries. TopLink has 5 query options available:
1. TopLink's Expression API
2. EJB QL
3. Custom SQL
4. Stored Procedures
5. Query By Example
Quick Tour overview: http://www.oracle.com/technology/products/ias/toplink/quicktour904/que01_01.htm
You can develop your queries directly in the API of your application or you can use the mapping editors (JDeveloper or Workbench) to declaratively construct your queries. I would recommend using the mapping editors and the expression framework. This will allow the tools to assist you as your application evolves. When mappings change you will be notified if they break any of your defined queries.
In the 10.1.3 documentation you can start learning about queries at:

Problem migrating Toplink Workbench project from 9.0.4.5 to 10.1.3.1.0

Hi all,
I am having problems migrating my Toplink Workbench project from 9.0.4.5 to 10.1.3.1.0! I used the Toplink Workbench to open and convert the existing project. The conversion succeeded, but when I tried to export the mappings I got this:

Persistenance for Java Objects Using Toplink

Hi All Happy New Year
I am trying the a tutorial in Jdeveloper 10.1.3.0.4 called
Provide Persistenance for Java Objects Using Toplink.
I have followed the instructions and get the following error.
com.evermind.reflect.UndeclaredExceptionTypeException: oracle.oc4j.rmi.OracleRemoteException
at __Proxy1.persistEntity(Unknown Source)
at acme.ejb.session.EmpSessionClient.main(EmpSessionClient.java:29)
oracle.oc4j.rmi.OracleRemoteException: Invocation error: java.lang.NoSuchMethodException: acme.ejb.session.EmpSession.persistEntity(java.lang.Object)
The release notes mention TopLink POJO's Must Implement java.io.Serializable When Returned From a Session Bean's Remote Interface (4902787) When creating a session bean facade for TopLink POJO objects, you must implement java.io.Serializable for each of the TopLink POJO objects returned from the SessionBean facade through a remote interface. This is typically required when using ADF Swing, a EJB Sample Client, or when your EJB Session Bean resides on a separate application server from the client. You can also tell you you need to implement java.io.Serializable when you get the following exception:
com.evermind.reflect.UndeclaredExceptionTypeException:
/oracle.oc4j.rmi.OracleRemoteException/
at __Proxy1.[Your Class Name Here] (Unknown Source)
The workaround is to manually edit each POJO object to implement java.io.Serializable.
I have only one POJO which is declared as follows:
public class EmpInfo implements Serializable {
Can anybody help me understand what I need to do to get it to work?
Many Thanks in Advance

Hi,
can you send me your test scenario/project at anuj dot k dot jain at oracle dot com. I tried reproducing this but was unable to do so.

Toplink workbench exception

One of our teams is having the following problem:
when we refresh one class in toplink workbench to add a new field, we can no longer save. we get the following error. What is curious, is that our local classes get listed in the workbench. I'm not sure exactly what this means, and the classes referred to in the stack trace are our local framework classes. Has anyone seen something like this before, or have an idea of what it might mean?. Once again the error below is shown in the workbench not runtime.
LOCAL EXCEPTION STACK: EXCEPTION [TOPLINK-6004] (TopLink - 4.0 (Build 345)): com.webgain.integrator.exceptions.QueryException EXCEPTION DESCRIPTION: The object [BldrClass[3c8807] (com.cna.exceptions.CfRuntimeException, modifier = public, array=, implements [BldrClass[3aa0bb] (com.cna.exceptions.CiException, modifier = public abstract interface, interface, array=, implements [])], extends RuntimeException)], of class [class com.webgain.workbench.model.meta.BldrClass], with identity hashcode (System.identityHashCode()) [3,966,983], is not from this UnitOfWork object space, but the parent session's. The object was never registered in this UnitOfWork, but read from the parent session and related to an object registered in the UnitOfWork. Ensure that you are correctly registering your objects.

The easiest workaround to this problem is normally to perform a "save as" of the project, which will normally work.
TopLink - 4.0 (Build 345) - is a fairly old release, you may wish to contact support to get the latest patch for this release, or to upgrade to a newer version of the product.

I am using 10.1.3.0.1 and for me there are still grave issues with interface management in the WB.
First of all, I get a NullPointerException when clicking the "add" Button on the interface descriptor's implementor list after having refreshed all classes by selecting the project packages and doing "refresh classes" from the context menu. I have to close and restart the WB in order to be able to continue working.
Then, some attributes which are not common among the implementor classes are detected as common query keys.
Lastly, if I use variable one-to-one relationships and de-select some class indicator values, the de-selected implementor descriptors are displayed as selected after workbench restart again, showing me errors about missing class indicator values for selected descriptors (Error 0055).

EJB3.0 and toplink workbench

Hi,
I have a question to the new TopLink release and EJB 3.0 support.
Is it possible that TopLink workbench generates EJB 3.0 persistence classes from database with annotations or mappings in the project.xml?
I don't want to write all the persistence classes with annotations by myself.

EJB 3.0's Java Persistence API (JPA) is not supported directly from the workbench. You can however take your existing TopLink XML config files (sessions and Map/Project) and use them with JPA (no annotations).
When working with annotations it becomes more relevant to be doing these operations within an IDE. To this end we have already delivered early support for JPA in JDeveloper. You can generate a persistent entity model from tables with full annotations and then generate a session bean facade exposing the persistence operations as needed.
For those of you not using JDeveloper we are also leading a project to add this functionality to Eclipse within WTP. For more information on project dali go to www.eclipse.org/dali.

How can I use TopLink for querys that have two and more tables?

I use TopLink today, and I can use one table to query, but how can I use TopLink for querys that have two and more tables?
Thank you for see and answer this question.

You can write a custom SQL query and map it to an object as needed. You can also use the Toplink query language "anyOf" or "get" commands to map two tables as long as you map them as one to one (get command) or one to many (anyOf command) in the toplink mapping workbench.

How to use ejb2.0 in Jdeveloper 10.1.3

Hi,
I am developing a application with the following cofigurations
EJB2.0 Session Beans
toplink
jdk1.4
JDeveloper 10.1.3
Oracle AS 10.1.2
I have done the toplink mapping with the database tables as POJO's.
Now, when I try to create session bean (EJB2.0) as a business component and selected the check box (Generate Session Facade methods) but the wizard doesn't prompts for the methods to be exposed, however the wizard prompts for methods when i use EJB3.0.
please clarify on this.
Thanks & Regards

If I'm not mistaken we add the automatic creation of session facade EJB for TopLink/JPA in 10.1.3 - and we only did this for EJB 3.0 Session Beans.
Given all the improvements and simplifications that EJB 3.0 brings over EJB 2.0 maybe you should consider switching your development to use EJB 3.0.
Note that you can configure an OC4J 10.1.3 to run under OAS 10.1.2 and thus get EJB 3.0 support in 10.1.2.

Can we pass the HashMap object to Stored procedure using toplink

Can we send the java.util.Map object as input to the stored procedures.
Can any one please tell how we can do this using toplink.
I tried to do that by doing following steps
1. Crated the
-- Column Name - Value Pair
CREATE TYPE col_data_pair IS OBJECT (column_name varchar2(50), data VARCHAR2(32767))
2. create or replace PROCEDURE XL_MAP_TEST (poData In COL_DATA_PAIR) as
v_timestamp TIMESTAMP;
BEGIN
INSERT INTO RECON_ATTR_UD_TFCHILD(RECON_TABLE_KEY, RE_KEY, RECON_UD_TESTFORM_KEY,RECON_UD_TFCHILD_GROUP)
values (RECON_TABLE_KEY_SEQ.NEXTVAL,15, 25 ,'Persistentss23');
END XL_MAP_TEST;

Hi
Thanks for your inputs. Can you please send me the code stuff how we can use ObjectRelationalDescriptor. I tried to do that by doing following steps
1. Crated one class
oracle.InputOfTypeMap poData =
                    new oracle.InputOfTypeMap();
poData.setKay("ddd");
poData.setValue("ddd");
2. oracle.toplink.objectrelational.ObjectRelationalDescriptor descriptor =
     new oracle.toplink.objectrelational.ObjectRelationalDescriptor();          descriptor.setJavaClass(oracle.iam.reconciliation.vo.InputOfTypeMap.class);
          descriptor.setStructureName("COL_DATA_PAIR");
          descriptor.addFieldOrdering("column_name");
          descriptor.addFieldOrdering("data");
          descriptor.addDirectMapping("key", "column_name");
          descriptor.addDirectMapping("value", "data");
3. I was not sure how to use this further StoredProcedureCall
Can you plese help me, how we can do that?

How to use toplink "build expression" with soundex function

We are using toplink experssion builder to build the query. can any one help me on build a query with soundex using toplink..
for example :
SELECT last_name, first_name
FROM hr.employees
WHERE SOUNDEX(last_name)
= SOUNDEX('SMYTHE');

TopLink's ExpressionOperator does have an operator defined for soundex. I have an example that uses it that I customized to match you case.
I would recommend defining these queries as named queries using an after-load method:
    public static void afterLoadEmployee(ClassDescriptor descriptor) {
        ReadAllQuery raq = new ReadAllQuery(Employee.class);
        ExpressionBuilder eb = raq.getExpressionBuilder();
        Expression fnExp =
            ExpressionOperator.soundex().expressionFor(eb.get("lastName"));
        Expression valExp =
            ExpressionOperator.soundex().expressionFor(eb.getParameter("L_NAME"));
        raq.setSelectionCriteria(fnExp.equal(valExp));
        raq.addArgument("L_NAME", String.class);
        descriptor.getDescriptorQueryManager().addQuery("Employee.findBySoundexLastName",
                                                        raq);
    }Now you can execute the query anywhere in your application using:
        List<Employee> emps =
            (List<Employee>)session.executeQuery("Employee.findBySoundexLastName",
                                                 Employee.class, "SMYTHE");The SQL generated is a little different due to the multiple tables used in the employee example model but here is what I got:
SELECT t0.EMP_ID, t1.EMP_ID, t0.F_NAME, t1.SALARY, t0.L_NAME, t0.GENDER, t0.VERSION, t0.ADDR_ID,
t0.MANAGER_ID, t0.END_DATE, t0.START_DATE FROM EMPLOYEE t0, SALARY t1
WHERE ((SOUNDEX(t0.L_NAME) = SOUNDEX('SMYTHE')) AND (t1.EMP_ID = t0.EMP_ID))Doug
