I have an old (inherited) project that I need to deploy on AWS but I get some problems related to the template folder.
This project has an index.xhtml on "src\main\webapp" instead of "src\main\resources\templates", I think it is beacuse it uses jsf but I'm new on Springboot and jsf pages.
In the documentation I've got it says that in order to open the web you need to visit http://localhost:5000/index.jsf so to solve it I made a class with
#Controller
public class IndexController {
#RequestMapping(value = {"", "/"})
public String index() {
return "redirect:/index.jsf";
}
}
In local works but the problem I get is that when I deploy it on AWS with Elastic Beanstalk, I create a new Java application on it to upload the jar file made with maven.
But when I enter to the application I always get this message:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Thu Jun 18 14:52:25 UTC 2020
There was an unexpected error (type=Not Found, status=404).
/index.jsp
I try to:
Search where it's configured the custom folder but I didn't find it.
Move the index.xhtml file to templates but doesn't work.
Add to application.properties file spring.thymeleaf.prefix=classpath:/templates/ to set the default folder.
Instead of Java application I made a Tomcat application on Elastic Beanstalk and upload a war file made with maven but I get a tomcat 404.
The project has a page on swagger-ui to test de API Rest petitions, I don't know if it might cause some problems.

More Info:
I noticed that the WEB-INF folder was missing so I created it (also clasess and lib folders) and I added these files.

I am trying to open index.html from eclipse. But I got this error:
javax.servlet.ServletException: Resource configuration class
com.sensorhound.things.rest.ThingsApplication could not be loaded.
I am using java EE framework.
Previously, I am writing my front-end code using a Node.js fake server. Then I create a maven project in eclipse to write my back-end code. And I didn't move my front-end code to this project until I finish writing up the back-end code.
What I did to test my front-end code before was start up my wildfly server and Cassandra database, then I will do a mvn wildfly:deploy under my back-end project directory. Then I will go to the front-end code folder and open the index.html in browser. It works fine.
Now I need to wrap up my project so I copy my front-end code to
src/main/webapps
directory, and update my project.
But when I try to open the index.html from eclipse. It give me this error.
For more reference, here is my web.xml:

If you need more information, I am willing to share.
Thanks!
I solve this by remove servlet related tags in web.xml. Those are the code my co-workers added when using jetty server.
I have created a simple helloWorld maven dependency and placed that in my springmvc projects pom.xml but while deploying its showing bean creation exception of that helloWorld: not a qualified bean.
Any help would be appreciated. Thank you.
Here how my dependent project looks like
My Application.java
package com.test
#Configuration
#EnableAutoConfiguration
#ComponentScan({"com.test"})
#EnableTransactionManagement
public class Application {
public static void main(String[] args) {
System.out.println("hai");
SpringApplication app = new SpringApplication(Application.class);
app.run(args);
}
}
My Controller
package com.test.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import test.Application;
import test.controller.Check;
#RestController
#RequestMapping("/Rest")
public class Controller {
#Autowired
Check check; // this is the bean from that dependency
#RequestMapping(value="/logs",method=RequestMethod.GET)
public String logs(){
return "I am the controler";
}
}

Edit: I am running tomcat 8 I will try with tomcat7 and see what will happen.
Edit2: I am using the command "mvn tomcat:run" so I tried adding a servlet of my own that inherits HttpServlet class the same error occurs saying java.lang.ClassCastException: com.dev.backend.services.Hi cannot be cast to javax.servlet.Servlet
This means I think that something is wrong with the tomcat or that command.
can anyone help, please?
When I am creating a new Spring MVC project using eclipse and maven, it throws the following error when I do a run as maven build(goal is tomcat:run). I did the build after clean and install.
SEVERE: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener
The other solutions for this problem are to add the maven dependencies in deployment assembly from the project properties.
But, the deployment assembly option is not present when I right click the properties.
I also tried adding spring.jar manually.
The class org.springframework.web.context.ContextLoaderListener is present in the maven dependency and still the error is thrown.

This is because you mark your Spring dependencies with <scope>provided</scope> on your maven pom.xml and you did not include the actual jars on the classpath when running the program. There are two possible solutions:
Change the dependency scope into compile
Include the spring jars with matching version to your classpath when running the application
I have created a new Spring MVC project using maven-eclipse and the following error is thrown:
(I tried some solutions from the stackoverflow which is not working in my case. Some problem with the pom.xml which I could not find. I added provided scope for the servlet-api and tried which was not working either.)

provided has this description:
This is much like compile, but indicates you expect the JDK or a
container to provide the dependency at runtime. For example, when
building a web application for the Java Enterprise Edition, you would
set the dependency on the Servlet API and related Java EE APIs to
scope provided because the web container provides those classes. This
scope is only available on the compilation and test classpath, and is
not transitive.
from the maven docs. You're basically telling Maven to provided the jar for compilation, but, at runtime, use some other, the servlet container's, jar.
In your case, ClassCastException seems to be because of classes being loaded by different classloaders. Say, you have the servlet-api.jar included by mistake in your WEB-INF/lib and you had set PARENT_LAST true for your webapp class loader. If you are running on an application server like WAS, this would mean you are loading interface with one class loader (some class loader at the top) and implementation (servlet-api jar just an e.g.) with another class loader at the bottom.
Keep scope as 'provided' and try keeping that jar in tomcat/lib folders. This is because of each class loader of respective war tries to load its own Servlet-api classes separately,compared to application class loader which loads the Servlet-api classes at container level.
So if u can make the jar moved to CATALINA_HOME/lib.you have required set of classes loaded by application class loader only and same version will be referred across by all wars.
scope 'provided' conveys to class loader at war level that the classes required for this is already loaded by application class loader and insists class loader at its war level may not required to create separate instances or version for it that cause class cast exception
Which application server you are using? I think Servlet jars files should be provide by your application srver.
