The better approach is that you have to create a bean with session scope using <jsp:useBean/>, on server code update the bean's attributes and in view (jsp) page embed bean's property value to the <input/> attributes.

<form method='post' action='your_action'>
  <input type='text' value="<c:out value='${bean.name}'/>" name='name'/>
</form>

<input type="text" name="email" value="<c:out value='${param.email}'/>"/>

This displays the value of the email request parameter in the email text box. Initially, this parameter won't exist, so the text box will be blank.

Note the use of the <c:out> JSTL tag, which allows HTML-escaping the value of the parameter.

Your form parameters should be wrapped in a element. When submitted they will be sent to server using request parameters.

Then in your jsp file you need to render those request parameters in the places they should appear. Initially they will be empty, so user will see them rendered as initial blank values to fill.
