TopLink support DB2/OS390

Does TopLink support connecting to DB2/OS390? If so, is it with the standard DB2 selection in Workbench, or will another method be required?
Thanks

Sorry, meant to say DB2 on AS/400. We do have a number of customers using TopLink on AS/400 with DB2. I do recall experiencing an issue with the JDBC driver IBM provided though. It would not properly report the meta-data information the Mapping Workbench uses to import schemas. To work around this, we manually entered the table information in one case, and in another case we exported the schema to another platform and imported it through a better JDBC driver. I'm sorry I can't confirm which specifric versions this was for. It is a documented limitation of the IBM JDBC driver however. Other than that, we had no problems at all.

Does Toplink 9.0.3.5 version support DB2 Version 8

Hi
In our enterprise, we use Toplink 9.0.3.5. This is an old version of toplink.
DB2 is the database used in our enterprise.
Now, our enterprise is planning to upgrade to DB2 Version 8.
I would need to know whether Toplink 9.0.3.5 version will support DB2 Version 8.

We have certified 9.0.4 against DB2 v8. The details are available here.
I have no reason to believe 9.0.3.X would not function with standard functionality offered by this version of DB2. If you encounter specific issues please let us know and we'll do our best to provide some solution options.

Does TopLink support arrays of primitive types?

Does TopLink support arrays of primitive types?

You must use a collection.
If you really wanted to you could store the data as an array and use get/set methods to convert between the array and collection, or customize your own ContainerPolicy, however arrays a very inefficent to add/remove from so TopLink only provides support for collections.

TopLink support for Stored Functions

I know that TopLink supports PL/SQL stored procedures. What I haven't been able to figure out is whether or not TopLink also supports functions as well. Is there any way to execute a PL/SQL function using the TopLink APIs? Thanks. -Michael-

You can find additional information (including examples of usage) on using Stored Functions in the TL Dev Guide: http://download.oracle.com/otn_hosted_doc/toplink/1013/MAIN/_html/qrybas004.htm#BCFBBJBJ

TopLink support for version 2.0/2.1 of ejbql

Hello,
TopLink support ejbql for pojo finders.
What version of ejbql is supported in toplink 9.0.4.8 : 2.0 or 2.1 ?
What version of ejbql is supported in future release (10.1.3) of toplink : 2.0 or 2.1 ?

I believe the answer to both is 2.1.

Does toplink support selecting an interval from a ResultSet ?

Hi,
I wonder if Toplink supports selecting an interval of rows before creating Java objects. I think I can do this myself using CursorStream but that would take more time to ignoring created java objects than ignoring items (rows) from query result.
actually the purpose is to simulate cursor. since a cursor is quite expensice to keep in memory for long time, but still the applications, working with a paging logic, want to select one page of objects each time they make a call to toplink, I need to provide them with this functionality.
for example there is a retrieve request that would result in 1000 objects. in the first call, they want to retrieve 0-50, in the second call 50-100, and so on.
ps : I don't let these applications keep a cursor on behald of them on the server.
thanks.
Erdem.

ScrollableCursors support intervals and positioning the result set.

Spring TopLink support outside container

I'm setting up an internal workshop at our company to teach and demo TopLink. I'm aiming to focus on TopLink, so I figured I would keep it as simple as possible.
I still want to demo transaction spanning several DAO calls though, and thought I could use the TopLink support in Spring for that. Easier said than done when I'm only running from a simple class' main method...
First I try starting a transaction with Spring, as I thought it would be able to fallback/handle it with a ThreadLocal even though it's not inside a container:
TransactionDefinition transDef = new DefaultTransactionDefinition(
TransactionDefinition.PROPAGATION_REQUIRED); TransactionStatus
TransactionStatus transStatus = transManager.getTransaction(transDef);
Which gives:
java.lang.UnsupportedOperationException: SingleSessionFactory does not support managed client Sessions
So I figure, alright, fair enough. All I have to do then is initialise a UoW through spring instead of starting a transaction, and then that will be injected into the TopLinkCallback I'm using in my DAO:
SessionFactory sessionFactory = (SessionFactory) appContext.getBean("sessionFactory");
Session currentSession = SessionFactoryUtils.getSession(sessionFactory, true);
UnitOfWork uow = currentSession.getActiveUnitOfWork();
But nope. The getActiveUnitOfWork() in my TopLinkCallback just returns null. Anyone know how to do this best outside a container? How do I initialise a UoW that Spring will hold on to for me?
Anders,

Hi Anders,
SessionFactory sessionFactory = (SessionFactory)
appContext.getBean("sessionFactory");
Session currentSession =
SessionFactoryUtils.getSession(sessionFactory,
true);
UnitOfWork uow =
currentSession.getActiveUnitOfWork();
But nope. The getActiveUnitOfWork() in my
TopLinkCallback just returns null. Anyone know how to
do this best outside a container? How do I initialise
a UoW that Spring will hold on to for me?
Anders,You're getting the expected behavior. getActiveUnitOfWork returns null outside of a transaction. It won't start one for you--you're going to have to do that before you call it.
If you put your code inside a transaction callback like the following you get an active unit of work.
final ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-toplink.xml");
PlatformTransactionManager txManager = (PlatformTransactionManager) ctx.getBean("transactionManager");
TransactionTemplate template = new TransactionTemplate(txManager);
template.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
TransactionCallbackWithoutResult callback =     new TransactionCallbackWithoutResult() {
     protected void doInTransactionWithoutResult(TransactionStatus transactionStatus) {
          SessionFactory sessionFactory = (SessionFactory) ctx.getBean("sessionFactory");
          Session currentSession = SessionFactoryUtils.getSession(sessionFactory, true);
          UnitOfWork uow = currentSession.getActiveUnitOfWork();
          // uow is not null
          // your code goes here
// execute your code in a tx
template.execute(callback);This code runs out of container no problem. I tested it with the petclinic example. Hope this helps.

Does TopLink support JBoss App Server?

My company is a software development company. So, we use many application servers for our customers.
I found that TopLink supports OC4J, WebLogic and WebSphere, but I don't know, Does TopLink support JBoss? I just downloaded TopLink for test yesterday, so, I don't know much about TopLink, but my current project uses JBoss.
Please give me some suggestion that might help me to refine my project.
Thank you so much.

Yes it does and there are customers using JBOSS. TopLink supports any app server and, in fact, doesn't even require an app server -- and compliant JVM will do just fine.

Supported DB2 versions in WL8.1

Hi :
We currently have Weblogic 8.1 connecting to DB2 V8.1, and want to upgrade the DB2 to version V9.7. We have the proper files, have modified the class path accordingly, however the driver isn't recognized.
Does anyone know if WL 8.1 even supports DB2 V9.7?
Thanks in advance.

Hi,
You can check details with supported configuration for WLS 8.1

Toplink support for DB2

I was wondering if anyone had any experiences with Toplink's support for DB2? If I have an existing application working with Oracle, is it easy to get the application working with a DB2 database or another DBMS such as SQL Server, etc.? Obviously, the different vendors have different conformities to the SQL syntax standard, and I was wondering if Toplink took these differences into account?
Thanks,
Ted

I don't know of any specific papers/docs on this.
The nature of TopLink is supporting any app server, any ide/toolset and any Database. For example, look in the source.zip file in your lib directory for TopLink... Notice there is a DB2Platform.java file in there. If there were any specific compatibility or idiosynchracies we hadn't accounted for (but we have), you could easily do so yourself just by modifying that class. We have cusotmers using dozens and dozens of different database variants just by using and modifying any of the Platform code provided...

Toplink support for Java 5.0

I tried to import java classes, compiled with jdk 5.0
into Toplink workbench. The mapping fails.
I tried to run the workbench with jre 5.0 but that didn't work either.
Does anyone know how to do it and does Toplink even have a version that supports java 5.0?

Anna,
TopLink 10.1.3 will offer formal support for Java 5.0. Currently the runtime should work fine with Java 5.0. The only issue may be the workbench mapping process depending on the version of TopLink you are using.
If you are using the 10.1.3 preview the workbench will still run with JDK 1.4 but should be compatible with importing and mapping classes compiled with JDK5. We will upgrade the JRE used by the workbench to JDK5 for the production release but this should not make any difference to your ability to map JDK 1.4 or 5 classes and use either at runtime.
If you are using 9.0.4.X then the workbench will not be able to run or import JDK5 compiled classes. I believe the runtime is fine but not certified. For this environment you will need to compile the classes under JDK 1.4 and map this version of the classes. You can then use JDK5 compiled version in conjunction with the runtime.
I hope this helps,
Doug

Toplink support for SQL Server 2005 on Websphere 6.1

Hi,
We are using toplink in our application, it works fine when we use it with weblogic & SQL server or WAS 6.1 with Oracle or DB2. But when we use it with WAS 6.1 and SQL Server 2k5, it just does not work. It takes up all the connections in the pool and never returns it and starts giving connection time out errors.
Internal Exception: com.ibm.websphere.ce.cm.ConnectionWaitTimeoutException: Connection not available, Timed out waiting for 100005Error Code: 0
Thanks

This sounds like a WebSphere connection pool issue, I'm not sure why WebSphere would not work with SQL Server.
You could try using TopLink's internal connection pooling instead.
