Invoking custom methods in application modules

Question

Hi,
I am absolutely new to oracle ADF.I was recently working with application module.My question is how do I call a custom method(say myCustomMeth(String str) ) residing inside my application module from my Managed bean?I saw one example where the operation(i.e. the method) was directly dragged and dropped onto the jspx page from the data control.Is it the right way of doing it?I also saw one example where operation binding was used to invoke a method inside the application module although I didn't understand the code fully.I am really confused now.Please help.
Thanks in advance.

By doing so, the custom operation becomes available in the AM Data Control and can be bound to your jspx page.

1. You can drag the custom method from the data control in JDeveloper and drop it in your page as a command button or link to create a method binding declaratively this way. The method binding is executed via some command button or link and your custom AM method is called, or
2. You can create the method binding yourself in the bindings tab of you jspx page, add the command button in your page and define an action listener for it in your backing bean. In your backing bean action listener you can write the necessary code to execute the method binding, which will call your custom AM method.
Hope it is clear.
