Start a new thread.
Create separate classes with methods for connecting, reading/inserting/updating the database. I propose a different class per database table.
Then write the html code (JSP page) and call those methods.
Also read the tutorial at the top of the JSP forum about MVC Connectivity

Moved to new thread, and as javaAddict suggested you should have look at this tutorial JSP database connectivity according to Model View Controller (MVC) Model 2
PS: Would be nice if you read forum rules specially about keep it organized and not hijacking other people posts or reopening old threads....
