Question

I wrote a simple servlet as follows:

public class MyServlet extends HttpServlet {
    public void doGet(HttpServletRequest request, HttpServletResponse response)
           throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        // [do stuff with the PrintWriter]
        out.close();
    }
}

Is it necessary to close the PrintWriter out stream? If I don’t close the stream will that affect anything further?

Answer 1

If it’s not you that’s opening the stream, you should not close it.

The stream is opened by the container so the responsibility for closing lies with it.
