回答1:

Try to use JSTL & EL instead of Scriplet elements. For database access use JSTL SQL Tag library or it's better to move the database code in the Servlet.

Try with the CSS Input Radio checked Property

Sample code:

    Male checked> Female checked>

EDIT

For check box values single value its show properly but when it multiple values showing nothing.

check the string using contains method.

sample code:

  English checked> Kannada checked> Hindi checked>
