Первый подключаемый модуль сервлета слияния, проблема ClassCastException
Я пытаюсь передать привет world "плагин сервлета для Confluence. В atlassian-plugin.xml у меня есть
<servlet name="testservlet" key="testservlet" class="com.test.confluence.plugins.testservlet.TestServlet">
<description>A test servlet.</description>
<url-pattern>/testservlet</url-pattern>
</servlet>
В pom.xml у меня есть
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
Вот сервлет
package com.test.confluence.plugins.testservlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
public class TestServlet extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("Hello World");
out.close();
}
}
. Он строится и устанавливается, но когда я нажимаю сервлет на / confluence / plugins / servlet / testservlet, я получаю страницу, которая не найдена, и это исключение ClassCastException:
