Please refer to the documentation for detailed differences.

One of the differences is , in request.getParameter("var") method,
you get the parameter value of the variable "var" which was sent through the HTML page and return a String value.
But in case of the request.getAttribute(Object o) method, you get the attribute added for Object o as the return value. These value are not sent through some of the component on the HTML form rather in the jsp page which produced that particular HTML page must code it like -- request.setAttribute(name, value).

Hope it helps a bit.

As Mishra said, read the docs. There is no other better substitute.

"Maureen",

There aren't may rules that have been put into place here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!
