Avrom’s Java EE and Oracle ADF Blog

This is the second part of a two-part series about undocumented tricks with shared application module instances. Last week, I talked about calling methods (at the application module, view object, or view row level) from shared application module instances. This week, I’m going to talk about displaying data (in a non-LOV context) out of them. If you want a general overview of what shared application module instances are and why I think using them is a good idea (particularly at the application scope), look here.

Last week, I talked a bit about the advantages of using shared application module instances, particularly those scoped at the application level. As I said there, creating shared application module instances is described in Chapter 10 of the Fusion Developer’s Guide for Oracle ADF, as is their primary use, containing view object instances for lookups, to be used in validation and LOV attributes.

This week and next, I’m going to talk about other things you can do with shared application module instances, things that aren’t as well documented. This week, I’ll talk about calling service methods on shared application module instances, the view object instances in their data model, or particular rows from thise view object instances; next week, I’ll talk about actually displaying data from the shared instance’s data model as components (other than choice/LOV components) on a page.
