Answer is 1. The Servlet will output 'javabeat null' in the Server Console.

init-param tag is part of <servlet> not <servlet-mapping>

So, above code will print 2 nulls.

Hello

I think we get a compile time error by declaring <init-param> as a subelement of <servlet-mapping>. I am using eclipse and it gives me a error if I give <init-param> under <servlet-mapping> element.

IDEs like eclipse, netbeans can have schema validation enabled.
Because init-param is not a part of servlet-mapping it schema validation fails and eclipse reports it as a error in the problems view.
(one can disable the validations in the eclipse preferences)


Also, if you have XML-Validation turned on in the container(I am taking about Tomcat, I don't know how to do it in others) web application won't start/load.
