Yes u can use a separate plain java class to acess database...thats what the MVC architecture is, your java file will behave as model that handles..data and db connectivity, while your Servlet will behave as controller, that calls your business code..which is in a separate reusable java file..
is it fine to have normal java class to handle database connection with servlet? [closed]

If you are writing a web application accessing a DB, then I suggest that you use some Persistence API, such as JPA or Hibernate. if you are using Eclipse or another IDE, the ability to reverse engineer your Entities from the DB will save you a lot of errors and time.
