I doubt anyone wrote something like that and I would refrain from writing it
myself too. This goes against good design practices. You do *not* want to have
different servlets having 75% (or more) of their code almost identical.
Look at your code and factor out common things (database access, validation,
etc.). Create common database pool for all your servlets. Create a class which
has methods for executing queries, updates that returns a generic ResultsBean
that you can use in JSP. And maybe a one dispatcher servlet that will handle
validation and then forward request to worker servlets.
With those things in place writing new servlets that access database will be
trivial:
- get new DatabaseAccess class
- create the query from submitted request, determine whether it's search or
update or something else
- crate new ResultsBean
- get results: ResultsBean = DatabaseAccess.search(query)
- put that bean in some context
- forward to JSP
