Something wrong with Tomcat9

I have Ubuntu server on my computer and i have the tomcat9 there.

Last night everything was going well, put .war into webapp folder and it would run like it should on localhost:8080/app

Then i went to sleep and was prepared to continue from where i left off, but behold, yet again there is a problem with tomcat!

i restarted the server, went to /opt/tomcat9/bin and ran startup.sh

Using CATALINA_BASE:   /opt/tomcat9
Using CATALINA_HOME:   /opt/tomcat9
Using CATALINA_TMPDIR: /opt/tomcat9/temp
Using JRE_HOME:        /usr/lib/jvm/java-8-oracle/jre
Using CLASSPATH:       /opt/tomcat9/bin/bootstrap.jar:/opt/tomcat9/bin/tomcat-juli.jar
Tomcat started.

but at localhost:8080 is now unable to connect, as is the /app folder too.

In logs there is nothing.... It seems it dosent even write into logs anymore, last log post is from last night, despite running the server 5min ago.

Catalinalog (timestamp from last night)

07-Mar-2017 04:20:49.775 WARNING [http-nio-8080-exec-9] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/spring3-mvc-maven-xml-hello-world/hello2] in DispatcherServlet with name 'spring-web'

Catalina.out (also from last night)

./catalina.sh: 1: eval: /usr/lib/jvm/java-8-oracle/jre/bin/java: not found

Am i really just bad with the service or what, it feels like majority, somewhere around 70% of my time is wasted on debuggin Tomcat alone, I would totally love to actually work on my project instead of tomcat...

For Linux,

you can default set by using the following command.

sudo update-alternatives --config java

For more, you can go through this link: https://stackoverflow.com/a/37479837/2293534

Java Full Installation in Linux: https://www.digitalocean.com/community/tutorials/how-to-install-java-on-ubuntu-with-apt-get

For windows,

you can follow this link: https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html

UPDATE:

Run the following command

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre

UPDATE#2:

This is a suggestion. You can reinstall java8 and tomcat9 after removing current installation.

Full installation procedure is given here: https://tecadmin.net/install-tomcat-9-on-ubuntu/

Another installation procedure is also given here: http://www.linuxtechi.com/install-apache-tomcat9-centos7-rhel7-ubuntu16-04/

Seems your Java Runtime Environment is missing

That end of the catalina.out is rather revealing: it cannot seem to find the java executable!

Try in a terminal to write 

/usr/lib/jvm/java-8-oracle/jre/bin/java -version

Unless you get something along these lines...

java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

...then it is not your Tomcat that is broken but your Java Runtime Environment.
