How to use ApplicationModule custom methods in JSP?

Question

I have an ApplicationModule for which I have defined several custom methods (in the ApplicationModuleImpl class). I wish to invoke these methods from a JSP. I'm having trouble getting a scriptable reference to the application module object in the JSP. I can get data from the view objects using the jbo:xxx data tags, but I can't get any sort of reference to the application module object that would allow me to invoke the methods. I have tried editing the application module to expose the methods as client methods, but still can't get a reference to them.
My main questions:
1. Is there a way to invoke the custom methods somewhere between the jbo:ApplicationModule tag and the jbo:ReleasePageResources tag?
2. Is there a way to declare and use the application module without using the jbo:ApplicationModule tag? Would I ever benefit from doing this?

Answer 1

Alan, here's how to call a custom method String getSomeInfo() that I've created on my application module, MyModule in this example. Also, in this example the id parameter in the ApplicationModule tag is "am" (<jbo:ApplicationModule id="am"...):
First, edit your application module. In the app module editor, go to the Client Methods tab and move getSomeInfo into the selected list.
Next, edit your JSP to call your custom method.
<% MyModule myAm = (MyModule)am.useApplicationModule(); String someInfo = myAm.getSomeInfo(); %>
You also have to add the correct import statements to the page tag in your JSP:
<%@ page contentType="text/html;charset=windows-1252" import="oracle.jbo.*, MyModule.common.*"%>
Hope this helps
