Cloud Web Terminal running in Tomcat

[jesussaad]

Could you help me please open the terminal page when deployed in Tomcat?
I know the best way to run the cloudterm is standalone way from JAR, but I have no permissions for that in my Server, so I need run in Tomcat

This is my scenario was tried:

• I change the "packaging" pom.xml option to war;
• Change the "java.version" pom.xml option to 1.8;
• Run the tomcat 8.0.52;
• Deploy the cloudterm.war by Tomcat manager app;
• I try access the terminal in browser: http://localhost:8080/cloudterm/
• The expected terminal page is not showing, just the "HTTP Status 404"

Plus you need to setup a SpringBootServletInitializer class if you want to deploy it to standard servlet container. This will be picked up by tomcat and initialize your app.

See https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html

Thanks man!
Could you help me again found whats wrong is happen?
I do three changes like described in https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html and keep not working, but at least now is possible to see a evolution because when I access http://localhost:8080/cloudterm/ a blank web page is showing, but none is showing up in the log.

This is my complete pom.xml:

This is my main class changed:

package com.kodedu.cloudterm;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class AppStarter extends SpringBootServletInitializer
{
    public static void main(String[] args) {

        SpringApplication.run(AppStarter.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(AppStarter.class);
    }
}

And this is the log from catalina.out in app startup:
catalina.2018-06-13.log

PS.: I did the tests in Tomcat 8.0.52 (my current version) and Tomcat 8.5.31 (just for conference)
PS2.: I tried the cloudterm-0.0.1-SNAPSHOT.war and cloudterm.war files generated by "mvn clean install" from target folder and the result is the same

[jesussaad]

Plus I tried with Spring Boot 1.5.13.RELEASE and with ServletInitializer class like https://start.spring.io and the same blank page is showing.
Follow attached the Tomcat 8.0.52 log
catalina.out.log

Normally it should work, but it didn't work for me too. ServletIinitializer isn't triggered.
