How to call a AM method with parameters from Managed Bean?

Question

Hi Everyone,
I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
Class[] paramTypes = { };
Object[] params = { } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };
Object[] params = {aVal } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.

Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you
thanks
