Starting Java

Kyle D. Harris — Tue, 10 Feb 2004 08:20:14 GMT

I'm not sure why I can't view a JSP page. I must not have Java started. Can somebody explain to me what this looks like or what file it is i need to start? Thanks

That is the error i'm getting when i try to shutdown tomcat so i can then restart it. I shut down apache, then tried to shutdown tomcat so i can bounce it. What does this mean? Thanks

This is probably just in your browser settings. On mine it is under Edit > Preferences from the top menu bar.

Hi Kyle,

Are you trying to view jsp pages from a client point of view, in which case edit preferences is the way, or to server jsp pages from your server ?

Clients are trying to view JSP pages from there computers ... I can't get java to show up on my processes when i do a "ps -ef"

I am on a server though trying to fix the problem.

Hi,

My first bet would be to stop any iptables running : do you run such firewall ?

We have a firewall. I'm in the Marines on a base so it's a large Network firewall that I don't control. My other servers next to me are running it fine. Perhaps a reboot might cure all?

If it worked before on the same machine, yes, it could. Did it work already ? Can you get jsp pages from local ?

We don't have internet access from local ... I just got back from rebooting it (server's 2 miles away at another building)... In order to view it I need Apache, java, oracle and the listener running and I believe i have them all running.

You must not 'start' java. You must start tomcat.

The error you got shuting down tomcat may be multiplie cause.
- bad 'SHUTDOWN' setup in server.xml
- Tomcat is shutdown by send a request to it, on a separate port. So, if tomcat is not started correctly, you will get this error trying to shut it down.

Normally you view a jsp page by
1) putting the web application in $TOMCAT_HOME/webapps.
2) restart tomcat
3) check the logs to see if it started correctly.

If you want to view the jps, point your browser to
http://server:8080/mywebapps/mypage.jsp

First, make tomcat works standalone, then the next step will be to make the apache frontend
works...

If you have actual error messages, post them...
