Hi All,
I am new to java/jsp. I have made a jsp page. And i have included the java code in jsp itself using <%,%> tags. Now i want to move the code to java files keeping this as plain jsp. I think i need to use java beans.Can anyone plz let me know how do i go about it.One more thing, the jsp page was generated using a tool which we have.And i included my code inside it according to the way i want. The code selects table name from the dropdown and displays the corresponding columns of the table in the form of checkboxes. When any of the checkboxex is selected it inserts that column in another table.Following is my code
