  • This is useful to know too. When I needed to, I missed this:"Applications that run on Tomcat 9 and earlier will not run on Tomcat 10 without changes. Java EE based applications designed for Tomcat 9 and earlier may be placed in the $CATALINA_BASE/webapps-javaee directory and Tomcat will automatically convert them to Jakarta EE and copy them to the webapps directory." – Perkone Apr 07 '22 at 08:08

Make sure you have done below steps:

  1. Extends SpringBootServletInitializer 
@SpringBootApplication
 public class SpringBootWebApplication extends SpringBootServletInitializer 
{

@Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder 
application) {
    return application.sources(SpringBootWebApplication.class);
   }

  public static void main(String[] args) throws Exception {
    SpringApplication.run(SpringBootWebApplication.class, args);
      }

 }
  1. Marked the embedded servlet container as provided in you pom.xml
<!-- marked the embedded servlet container as provided -->
  <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-tomcat</artifactId>
      <scope>provided</scope>
  </dependency>
  1. Update packaging to war

<packaging>war</packaging>

  • Copy the generated war into Tomcat`s webapp folder and re-start tomcat.
  • Go to admin page of tomcat and see if you can find your your app and its status is running/started.While accessing URL make sure you are appending right context path,if defined using "server.context" property in application.properties file.

Paste any specific error in case otherwise,if you still face the issue.

  • Thank you @mahesh_Loya for the solution. – sujay kumar Mar 20 '18 at 15:46
  • Hi @Mahesch_Loya thanks for the solution. My spring boot app is deployed in the tomcat /attributes directory. I do not understand if I need to set the server.context property in the application.properties? My controller is expecting @RequestMapping("/") and when I go to https://servername/attributes/ I receive 404. The application was working fine locally responding to localhost:8080. My question is do i need server.servlet.context-path=/attributes in my application.properties. – Ana Sustic Sep 09 '21 at 08:44

    @Ana Sustic Is it possible for you to share a git link of your sample project? I will check and update. – Mahesh_Loya Sep 10 '21 at 15:22

    Hi @Mahesh_Loya thanks for the offer. I solved it. I had an incorrect end point. – Ana Sustic Sep 19 '21 at 15:04
