ADF page calling Web Service with multiple params the right way

Question

Hello,
I am using JDev 11.1.1.4.0.
I have an email notification web service that takes 4 parameters, from, to, subject and body. What I need to do is at the end of each 'Commit', call this web service to send notification to a group of audiences telling them a new record has been created. Following are steps I took to make it work:
1. Created a web service data control using the email notification WSDL.
2. Drag-and-Drop the data control on jspx page as ADF Parameter form.
3. Set Panel Form Layout's Visible property to 'False' so the controls doesn't show.
4. In a backingbean where method 'onSave()' is, I put the code to call the web service.
// in onSave() method after successful commit
      ValueExpression veFrom =
          efactory.createValueExpression(elctx, "#{bindings.from.inputValue}", Object.class);
      veFrom.setValue(elctx, "[email protected]");
      ValueExpression veTo =
          efactory.createValueExpression(elctx, "#{bindings.to.inputValue}", Object.class);
      veTo.setValue(elctx, "[email protected]");
// omitted rest of the params for brevity
      OperationBinding method = bindings.getOperationBinding("process");
      method.execute();This code works, but I am not sure if I am doing it right. For some reason, there is a better way of achieving what I need.
Many thanks in advance for your candid comments and suggestions.

Hi,
As you have dropped a method in the JSPX page as a parameter form, it adds unnecessary UI components, that you will NOT be using.
Instead of making the panelFormLayout visible property to false, delete it from the UI page.
Thus, you would have only the required method binding and the parameters defined as attribute values in the pageDef - which is as expected.
While deleting the panelFormLayout, delete it manually from the page source and doNOT delete thru the structure pane as it would delete the bindings as well.
