Hey guys,
I am coding a simple gae webapp that should send me an email from a form:
I have coded that gae code:
index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>A form</title>
</head>
<body>
<form action="/feedback" method="post">
<!-- Simple text field -->
<label for="name">Name </label>
<input type="text" name="name"/>
<br/>
<!-- Email -->
<label for="email">Email </label>
<input type="email" name="email"/>
<br/>
<!-- Textarea -->
<label for="description">Description </label>
<textarea name="description" cols="50" rows="5">Type your comment here
</textarea>
<br/>
<input type="submit" name="submit" value="Send Request" action=
"/feedback"/>
</form>
</body>
</html>
web.xml
<servlet>
<servlet-name>FeedbackServlet</servlet-name>
<servlet-class>at.wunderapps.servlets</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FeedbackServlet</servlet-name>
<url-pattern>/feedback</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
servlet:
import java.io.IOException;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@SuppressWarnings("serial")
public class FeedbackServlet extends HttpServlet {
@Override
protected void doPost(HttpServletRequest req, HttpServletResponseresp
)
throws ServletException, IOException {
String name = req.getParameter("name");
String description = req.getParameter("description");
String email = req.getParameter("email");
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
String msgBody = name + description + email + " :EMAIL";
try {
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("a...@gmail.com",
"Es FUNKTIONIERT!!!"));
msg.addRecipient(Message.RecipientType.TO, new
InternetAddress("my.m...@mail.com", "Your name"));
msg.setSubject("Bestellung");
msg.setText(msgBody);
Transport.send(msg);
} catch (Exception e) {
resp.setContentType("text/plain");
resp.getWriter().println("Something went wrong. Please try
again.");
throw new RuntimeException(e);
}
resp.setContentType("text/plain");
resp.getWriter().println(
"Thanks you for your feedback. An Email has been send
out.");
}
}
When I am doing localhost i get:
HTTP ERROR: 503
>
> Problem accessing /. Reason:
>
> SERVICE_UNAVAILABLE
>
and the exceptions I get are:
java.lang.ClassNotFoundException: at.wunderapps.servlets
CRITICAL: javax.servlet.ServletContext log: unavailable
javax.servlet.UnavailableException: at.wunderapps.servlets
20.07.2012 13:13:46 com.google.apphosting.utils.jetty.JettyLogger warn
WARNUNG: failed FeedbackServlet: java.lang.NullPointerException
20.07.2012 13:13:46 com.google.apphosting.utils.jetty.JettyLogger warn
WARNUNG: Failed startup of context
com.google.appengine.tools.development.DevAppEngineWebAppContext@495c998a{/,C:\Users\Desktop\mailservice\war}
java.lang.NullPointerException
I guess the problem could be that the inde.html does not find my servlet.
But why, cause the web.xml seems to be alright? Can you please help me?
I very much appreciate your answer!!!
PS.: I am running it on windows 7, eclipse.
