Don't worry. Nobody is going to ask you about problems you haven't faced at an interview.

Well, not sure what is your expectation on the answer for this question ...

For JDBC,
- security: SQL Injection (solution: PreparedStatement)
- performance/resource: connection/resultset/statement not close properly (solution: properly close in multiple finally{} of exception handling for each closing)
- design: repeating code (solution: Template Design Pattern, or use Spring JDBC Template)

... etc.

For Servlet/JSP,
- design: abuse MVC (solution: use framework, e.g. Struts ... but still able to abuse by sucks developer)

... etc.

Too little time allowed to program the solution.
Too little time allowed to test the solution.
Bosses who read an article about X being the greatest thing in the world and the solution that makes it unnecessary to hire smart, talented, and capable software engineers.

you get the idea.....
