tomcat7一直在说它正在运行，应用程序不起作用（Raspberry Pi）

Question

So to explain everything...

I had a perfectly working instance of tomcat7 working with an application in one of my directories. There were no problems.

I then switched it to wifi rather than the ethernet, and it stopped working. So I fixed my networking issue (set a static wifi ip), and tried but it still wouldn't work. Switched it back to ethernet and it didn't go back. So I went and sudo rm -r my-apache-folder and tried to reinstall. Nothing. Decided to then use apt-get to install tomcat7 and still nothing. Before it was due to JRE_HOME and JAVA_HOME not being set, and that might still be a problem but tomcat says it's running when it definitely isn't.

I don't want to flood you with server.xml or something like that until I'm asked to, so please help me and I'll respond efficiently, been working on this small problem for a week or 2 now, been using every aid on the internet to no avail.

port 8080 isn't running tomcat:

pi@raspberrypi:/$ sudo netstat -tlnp

Tomcat7 is "running":

pi@raspberrypi:/$ sudo service tomcat7 restart
[ ok ] Stopping Tomcat servlet engine: tomcat7.
[ ok ] Starting Tomcat servlet engine: tomcat7.

My java directories set in /etc/environment :

pi@raspberrypi:/etc/tomcat7$ $JRE_HOME
-bash: /usr/lib/jvm/java-6-openjdk-armhf/: Is a directory
pi@raspberrypi:/etc/tomcat7$ $JAVA_HOME

when i ran ps -ef|grep catalina :

pi@raspberrypi:/etc/tomcat7$ ps -ef|grep catalina

Answer 1

Ok so I "started from the bottom, now I'm here". haha I took the application and tested it on a separate computer, got it to work again, brought it back to the server, and got it back to where it was when I had this problem. In this case, however, I KNOW tomcat7 is running, and I can access the page. Now I feel that the issue of inactivity is most likely a problem with the address and how it's posted.

I'll update until it's solved!

NEW Catalina.out

update: fixed the above configuration issue, so it seems like I have everything working but the actual site. I have the correct IP and the correct port, meaning its a problem with the configuration. I tried using a non apt-get install (used a binary distro) and runs fine just like the apt-get package, but not working for my page. it goes to the "it works!" page on 8080, then I put a socket to listen to port 8080 and it doesn't respond. I check my router and everything is fine. This is driving me crazy.

update: port 8080 is closed externally but functions fine internally, most likely a problem with tomcat configuration/security
