我已经在App Engine上部署了Java Web应用程序,以前的版本可以使用,我只是在HTML和JS文件中进行了一些更改,然后重新部署了新版本,但是现在联系表格不起作用,它返回此错误为:
错误:服务器错误
服务器遇到错误,无法完成您的请求。

@SuppressWarnings("serial")
public class UnmundonuevoServlet extends HttpServlet {
public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException {
// set credentials
Sendgrid mail = new Sendgrid("UNAME", "UPASS");
String name=req.getParameter("name");
String email=req.getParameter("email");
String subject=req.getParameter("subject");
String message=req.getParameter("message");
// set email data
mail.setTo(email).setFrom("EMAIL").setSubject("Your request has been submitted successfully")
.setHtml("<strong>Hello "
+ "!</strong><br><br> We appreciate you contacting us, We will be in touch very soon.<br><br>Thank you <br> Nelly & Sandy");
// send your message
try {
mail.send();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Sendgrid mail1 = new Sendgrid("UNAME", "UPASS");
mail1.setTo("umnsica@gmail.com").setFrom("EMAIL").setSubject("New contact request from http://www.unmundonuevo.school")
.setText("Hello World!")
.setHtml("<strong>Hello "

PrintWriter out = resp.getWriter();
resp.setContentType("text/html");
resp.setHeader("Refresh", ".1; url=/index.jsp?message=Mail Sent Successfully#contact");
