I'm practicing my springboot knowledge so I'm trying to create a simple Todo Application. When I run my main app at localhost:8080/tasks/list, I'm getting a Whitelabel error page even If I configure the correct routing for my html file. I'm using JSP at this time, I also created a thymeleaf version of this but still I'm getting the same error. Thanks!
enter image description here
MainApp.java
package task.springboot.todo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class TodoappOracleApplication {
public static void main(String[] args) {
SpringApplication.run(TodoappOracleApplication.class, args);
}
}

Please add thymeleaf dependency to the pom.xml
<dependency>

and change the file extension from .jsp to .html (todo-list.html) and place it under path src/main/resources/templates

after trying multiple times on freemarker to work, I switched to thymeleaf and also faced the same problem. When returning the html file, it's just a string value and not the html file in the templates folder.
I don't know why it doesn't even start in console, when I watched youtube thymeleaf videos it shows in their console.
package com.example.demo;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class controller {
#GetMapping
public String getUser(Model model) {
model.addAttribute("something", "welcome to the club");
return "user";
}
}
here is the html file in main/resources/templates

Solved now, I replace #RestController with #Controller because #RestController adds #ResponseBody and prevents to get the view.
I am trying to map index1.jsp from controller.
Here is my controller method code:
#GetMapping({"/", "/hello"})
public String hello(Model model, #RequestParam(value="name", required=false, defaultValue="World") String name) {
model.addAttribute("name", name);
return "index1";
}
This is WebConfiguration:
#Configuration
public class WebConfiguration implements WebMvcConfigurer {
#Bean
public UrlBasedViewResolver viewResolver() {
UrlBasedViewResolver resolver
= new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
}
This is index.jsp
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Quiz</title>
</head>
<body>
<h2>Hello ${name}!</h2>
</body>
</html>
This is application.properties:
spring.application.name=quiz
server.port=8090
server.error.whitelabel.enabled=false
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

I am getting error: HTTP Status 500 – Internal Server Error
This is from console:

I think it look up at templates folder, and not in WEB-INF/jsp. If I try to map html file from templates it works. But with JSP makes problem.
Here it is a structure of application:

There are following steps you need to follow if you want to work with Spring boot + JSP instead of thymeleaf.
Remove thymeleaf dependency from pom.xml
Add below dependencies in pom.xml (Jasper to compile JSPs)
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- Need this to compile JSP -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>

I have created a war of springboot project using maven and did some changes to deploy the same on weblogic.

Welcome to Security Protection

</html>
The string returned by the home() handler method in your controller should be the name of the JSP view, without the extension. i.e. return "home";.
Try by adding the following dependency
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
</dependency>
Try this :
return "/Home.jsp";
I am trying to create a UI with JSP and SpringBoot using SpringMVC.
after all the configuration properly done i am still getting the error - "java.lang.ClassNotFoundException: org.eclipse.jdt.internal.compiler.env.INameEnvironment" I have tried so much to resolve it but still not working. if anyone can help me. thank you in advance.
