Difference between request scopes

<%= request.getAttribute("method") %> - 12

coz. request object will call the getAttribute method and get the exact value.

${requestScope.method } - 12

request scope same as above, it will get the value from the requestScope map.

${pageContext.request.method} - POST/GET

page context will give the request object and .method will define wht sort of request is it.
