Bean setter methods........

[Narasimha Rao B.]

Hi,

1. If there is no setter method is defined for a bean property will it be an error. In the jsp if we try to set the property value using <jsp:setProperty> what will happen??

2. If the setter method is present and we are not setting the value by using <jsp:setProperty> or by other means, will the default values(for stings empty sting and for integers 0 like ........) are set for these properties?

Thanks in Advance,

For <jsp:setProperty> standard action,
Internally JSP implementation object puts code to call setter method on the specified bean and when it doesnt find the setter method definition,
it shouts a compile error

To answer question 2, the default value will be however you defined the bean class.
For instance: (inside a class)
private String myValue1; // default is null
private String myValue2 = null; // default is also null
private String myValue3 = ""; // default is empty string
private String myValue4 = "study hard"; // default is study hard

// TODO create setter methods later

Passing SCJP first should answer question 2 too
