如下代码：
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
String testdbName = request.getParameter("testdbName");
String introduce = request.getParameter("introduce");
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");
out.println(" <BODY>");
out.println(testdbName);
out.println(introduce);
out.println(" </BODY>");
out.println("</HTML>");
本意是要读取jsp页面表单内的数据并写进数据库，但是发现Servlet没有把数据读出来，为此专门写了后面的out.println打印，页面完全空白。
各位大侠帮忙看下到底是哪儿出问题了？谢谢！
