Hi,

I am trying to create a scaffold spring mvc crud appliction using oracle database schema and keep getting

An internal error occurred during: “Scaffolding Spring MVC CRUD Application…”.
Native Library C:\oracle\product.2.0\client_1\BIN\ocijdbc10.dll already loaded in another classloader

I do not have any other application or program open which may be using this dll. I didn’t have trouble using derby db customer example. I am attaching the stack trace. Any help is appreciated. Thanks.

There is a known issue with using the OCI driver to scaffold with. If you can, try using the thin driver.

Thank you very much for your reply. I wish I know that before I spent so much time trying to make it work. I am now able to create the classes using scaffolding but still have an error running the app. I looked at forums, tried changing some jars with no luck. Hope you should be able to help with this too. Thanks

I removed maven capability and straight scaffolding worked. Adding maven support when creating the project downloaded jars which are not compatible, I couldn’t find the culprit. Thanks.

[chandusagi]

OK, ran into another issue. How to handle cross-reference table when using Spring Scaffolding. Since the table doesn’t have a primary key the generated code has errors. Am I doing it right?

[Heflin Hogan]

Are you referring to a table with 2 foreign keys used to join 2 other tables in a many-to-many relationship?

[chandusagi]

Yes, that is correct. I couldn’t get the project to work. It complains about not having primary key on that table. Is that a known issue?

[Heflin Hogan]

When selecting the tables for scaffolding, select both sides of the many-to-many relationship (not the join table), and on the panel where you select parent relationships, select both sides of the many-to-many. When you create the scaffolding, it will handle the relationship. However, the join table does have to have a primary key.
