Я следую за головой First Java.Простое развертывание сервлетов на Tomcat eclipse
Я создал простой сервлет, как они инструктировали, но они не писали, как его развернуть.
Я пытаюсь развернуть его на Tomcat 7, и я установил его через затмение.
Однако im получает ошибку 404 страницы.
Я создал web.xml Я также разместил файлы классов в WEB-INF/classes.
Вот код.
package org.code;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class KathyServlet extends HttpServlet {
public void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out;
String title = "PhraseOMatic has generated the following phrase.";
response.setContentType("text/html");
out = response.getWriter();
out.println("<HTML><HEAD><TITLE>");
out.println("PhraseOmatic");
out.println("</TITLE></HEAD><BODY>");
out.println("<H1>" + title + "</H1>");
out.println("<P>" + PhraseOMatic2.makePhrase());
out.println("<P><a href=\"KathyServlet\">make another phrase</a></p>");
out.println("</BODY></HTML>");
out.close();
}
}
другой Java-код файла:
package org.code;
public class PhraseOMatic2 {
public static String makePhrase() {
// make three sets of words to choose from
String[] wordListOne = {"24/7","multi-Tier","30,000 foot","B-to-B","win-win","front- end", "web-based","pervasive", "smart", "six-sigma","critical-path", "dynamic"};
String[] wordListTwo = {"empowered", "sticky", "valued-added", "oriented", "centric", "distributed", "clustered", "branded","outside-the-box", "positioned", "networked", "focused", "leveraged", "aligned", "targeted", "shared", "cooperative", "accelerated"};
String[] wordListThree = {"process", "tipping point", "solution", "architecture", "core competency", "strategy", "mindshare", "portal", "space", "vision", "paradigm", "mission"};
// find out how many words are in each list
int oneLength = wordListOne.length;
int twoLength = wordListTwo.length;
int threeLength = wordListThree.length;
// generate three random numbers, to pull random words from each list
int rand1 = (int) (Math.random() * oneLength);
int rand2 = (int) (Math.random() * twoLength);
int rand3 = (int) (Math.random() * threeLength);
// now build a phrase
String phrase = wordListOne[rand1] + " " + wordListTwo[rand2] + " " + wordListThree[rand3];
// now return it
return ("What we need is a " + phrase);
}
}

Извините, что я вложил неправильный xml, я изменил xml на правильное имя пакета, но он все же дал ту же ошибку, но я не заметил нижний регистр kathy, и как только я изменил его, он работал нормально. –
