I have a JSP page that has a JSP code fragment that fills up a string variable.
I also have some functions in JavaScript that need to use the string varaible as the input.
Can I use this a string variable from JSP in JavaScript? If so How?
Qu 2) The result from my JavaScript function will also be a String. I want to send that string as a hidden field in a form. How do I access JavaScript variables in HTML to be posted in a form?

You can't directly access the Java string in your page since the Java is executing on the server to format the page which is sent to the client.
What you can do, is to create JavaScript strings from the Java strings that will be sent to the client as part of the page.
For example:
