Issue
I have an HTTP 500 - Internal server error for java servlet. And I didn’t found a solution on forums for my case. I’m using IntelliJ Ultimate 2020.3 and Apache Tomcat Server 9.0.43. Here’s my projet files structure and my code. I have been looking for a solution for 3 hours now. Please,I need help.
The servlet class
package com.sdzee.servlets;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@WebServlet(name="Test",value="/test2")
public class Test extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
this.getServletContext().getRequestDispatcher("/../../main/webapp/test.jsp").forward(req,resp);
}
}
the test.jsp file
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Test</title>
</head>
<body>
<p>JSP test</p>
</body>
</html>
the servlet definition in web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<servlet>
<servlet-name>Test</servlet-name>
<servlet-class>com.sdzee.servlets.Test</servlet-class>
<init-param>
<param-name>Auteur</param-name>
<param-value>Moi</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Test</servlet-name>
<url-pattern>/test2</url-pattern>
</servlet-mapping>
</web-app>
and the results :
Solution
I think getRequestDispatcher("/../../main/webapp/test.jsp") should be getRequestDispatcher("/test.jsp")
