problem running webapp on remote server

I got tomcat 6 installed on my server,
so the address http://<server ip>:8080/
gives me the tomcat page, that's good.

I created a simple test app for tomcat that I run on my ubuntu desktop (tomcat is also installed on the desktop machine) so the link:

http://localhost:8080/EclipseServlet...pseFirstSevlet

gives me the proper output (note the misspelled "sevlet", whoops...)

however the link:

http://<ip address of server>:8080/EclipseServletTest/EclipseFirstSevlet

does not give me the correct output. I have the Webapp folder copied to the tomcat/webapps folder and I restarted the server...any idea what the problem might be?

I don't think I understand it well, Are you talking about two machines (server & Desktop) ? If so are you able to access the index page of the Tomcat in your Desktop?

Anything in the logs? You're giving us essentially nothing to go on.

Hi,
thanks for the replies.
I first created the test webapp on my desktop with tomcat running there...it worked. I then installed tomcat on my server, and got the tomcat startup page to appear, so tomcat was installed correctly and running on my server.

I then copied the test-webapp folder from my desktop/tomcat-install-folder/webapps to my server/tomcat-install-folder/webapps and tried to run it from there....I wasn't able to.
I get the following 404 message

HTTP Status 404 - /EclipseServletTest/EclipseFirstSevlet

type Status report

message /EclipseServletTest/EclipseFirstSevlet

description The requested resource (/EclipseServletTest/EclipseFirstSevlet) is not available.

there is this in the log....

I haven't seen the "address already in use" error before...that has to do with startup, not copying the webapp folder, right?
hope that clarifies

That means there's already a server running on that address (port). Maybe you need to shut it down before starting it.

but why would the regular startup screen work fine, while the testapp webapp wasn't visible?

No clue. Maybe because the server's already running and has an index.html in the root webapp, and it's *still* running, because it was never shut down.

At least one port is in contention.

theoretically, though....
I should be able to copy some app folder from the tomcat/webapps folder on one machine to the tomcat/webapps folder on another machine and have it run, right?

I'm assuming that's how people deploy their actuall apps....

In theory, sure, although it often requires a restart.

that's the thing....I did restart the server....I'll have to look through the web.xml more carefully, or just try a new one.

Java-based web applications are typically "deployed" by dropping the WAR file in the webapps folder. Copying entire folders with source code is typically not the normal course of action.

I would suggest that you create a WAR file for the web application and put that in the webapps folder. The web server should see the new WAR and "explode" it automatically.

It didn't restart if there was a port contention issue.
