Hello!
As for me it is better to follow examples from sound book to find out basics and do first steps!!!
Next, to reference property of bean
you should write #{beanName.propertyName}.For instance:
This resolves to getter of user list. Getter is method with name - getPropertyNameWithFirstCapitalLetter
To reference method you don't use any brackets.
Your method is:
public
String createOrder(){
//my operations
}
This method is referenced like #{userBean.createOrder}
