The difference is which user owns the process, which controls the permissions on the files. It is generally a bad idea to start the process as yourself, which is what happens with the latter form, as it will be pretty much uncontrollable by anyone else.

I've mande some progress. Found this article - http://cefn.com/blog/ubuntutomcat.html - that mentions a problem with Tomcat installation using Ununtu's tomcat5.5 package. Looks like Tomcat was not starting after all. Once I went through the recommended fix, I'm now getting a blank page when going to http://<ipaddress>:8080/dspace. At least there's no error message. I see catalina.sh in the list of processes, so I guess Tomcat is good now. Just have to figure out why I'm getting blank and not Dspace. P.S. What's the difference between using... sudo /etc/init.d/tomcat5.5 start ...and... sh /usr/share/tomcat5.5/bin/startup.sh ...to start Tomcat? I was using the former at first and wasn't seeing any errors for startup. -----Original Message----- From: LeVan,Ralph [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 16, 2007 10:32 AM To: Peter Urban; Stuart Lewis [sdl] Cc: [email protected] Subject: RE: [Dspace-tech] Completed install but page cannot be displayed There are a couple of ways to tell if tomcat is running. ps -eaf|grep tomcat The first part gets you a list of everything that is running on your machine. (Plain ps as you entered it just gets you the stuff running in your session.) The second part filters that long list down to things that have tomcat in them. If that returns nothing except the grep itself, try: Ps-eaf|grep catalina "catalina" is tomcats real name internally. Those two things will tell you about processes. The other trick is to go to the tomcat logs directory and see if you can see tomcat starting up in its logs. Typically, there is either a file named catalina.out or catalina.<dateTomcatWasStarted>.log. Inside them you will either see a line like "Starting service Catalina" or you'll see some sort of explanation for why tomcat didn't start. If you don't see any logs in the <tomcat>/logs directory, you probably never correctly issued the startup.sh script.

When I try to telnet, I get 'telnet: Unable to connect to remote host: Connection refused'. When is run 'ps', I get: PID TTY TIME CMD 6367 pts/1 00:00:00 sh 6369 pts/1 00:00:00 bash 6399 pts/1 00:00:00 ps Those results don't mean anything to me. Can you tell if Tomcat is running? -----Original Message----- From: Stuart Lewis [sdl] [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 16, 2007 12:55 AM To: Peter Urban Cc: [email protected] Subject: Re: [Dspace-tech] Completed install but page cannot be displayed Hi Peter, Something to try to see if tomcat really is running: What happens when you type: telnet localhost 8080 If you get a message something like 'connection refused' then it sounds like tomcat either isn't running, or is not listening on port 8080. Have you looked at 'ps' to see if it is listed as a running process? If the telnet command does work (you'll not see any output, just a blank prompt) try typing: GET / HTTP/1.0 And hit enter twice. Hopefully this will return some HTML (the tomcat homepage). This would show that tomcat is working. If tomcat is working, it might be that your server is firewalled from your computer running the browser. I don't know what a default Ubuntu firewall config looks like, but assuming they give you one, it is possible (likely) that a non-standard port such as 8080 is blocked by default, and you'll need to unblock it. Good luck!
