In new.jsp i wrote the code to save it in a database table..Not a good idea. JSPs are for formatting HTML, dealing with form input data is better done in a servlet, which then forwards to a JSP to generate a response.

Not generally. You need to take the text which is passed from the first form as a parameter and pass it to the JSP to insert in the HTML for the next form returned.
A servlet should handle to form return, get the text and other parameters from the request and store them as attributes in the request object, which the JSP then picks up and inserts in the text.
If the form starts to get complex you use a Java bean with a property for each field on the form, called a "data transfer object". The servlet loads this bean from the data returned by the form, validates and processes it, then passes it as a request attribute to the JSP which generates the HTML containing the data.
These days serious JSPs tend to use a tag library such as JSTL to handle the variable output, which will simplify this kind of process and avoid any java "scriptlets" in the JSP.
