"my self",

There aren't many rules that you need to worry about 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!

What is the purpose of the out.print statement in this form html?

Since the form has yet to be submitted, it's got nothing to show.

When you click the submit button control will be passed to the JSP page in the action attribute of the form. Is that another page or this same page?

Question : What if we want to do the same thing (print the "text1" on console) in "Servlet".

Java code in a JSP? In 2011? Really?

And, as the value of text1 can't be known until after the JSP executes and the page is sent to the browser where the user can enter the value, there is no way to do this.

I suggest you read this article to understand what JSP is and how it works.

What if the text1 is hard coded say like :
<INPUT TYPE="TEXT" NAME="text1" VALUE="My Value">

P.S : I know it might be a silly question, however I wanted to clear this point.

Still no. To the JSP engine the HTML markup is just template text. It makes as much sense to the JSP engine as wufgwukrfwrfgkuwgfrgfkwrkdkdwgckw.

Have you read the article?
