Tomcat 6.0.35 and java 8

Question

I'm trying to deploy spring boot application to Tomcat 6.0.35.

I downloaded sample application from www.mkyong.com and build .war application. I moved it to tomcat webapps directory.

I can access tomcat 6 homepage, and manager, and even deploy application, but when I go to http://localhost:8080/demo-0.0.1-SNAPSHOT, I get 404 page.

I'm not getting any errors, see below:

On tomcat 8 deploy works correctly, but unfortunately I have to use tomcat 6.0.35.

I'm using java 1.8.0_121-b13 oracle.

Have I missed some additional configuration?

Answer 1

I add spring-boot-legacy dependency:

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-legacy -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-legacy</artifactId>
            <version>1.1.0.RELEASE</version>
        </dependency>

Then I created web.xml in webapp/WEB-INF/ directory and filled with:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>com.mkyong.SpringBootWebApplication</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.boot.legacy.context.web.SpringBootContextLoaderListener</listener-class>
    </listener>


    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextAttribute</param-name>
            <param-value>org.springframework.web.context.WebApplicationContext.ROOT</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

Finally, the catalina.out file in /logs/ :
