vhost - servlets not available
Hey,
i deployed a gwt-application in tomcat 6.0.18 without any problems. I
pointed a url to the ip-adress and deployed the application unter
webapps/myfolder, so that the app was reachable unter http://mydomain/myfolder.
It worked fine.
But since im using a vhost in tomcat i got a problem.
Every time when gwt tries a callback i get the message: "Requested
resource not found". I did not make any changes in the web.xml.
I added the host like the following in the server.xml:
...
<!-- Define the default virtual host
Note: XML Schema validation will not work with Xerces 2.2.
-->
<Host name="srv2.tudom.de" appBase="tudom"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
<!-- VIRTUAL HOST INJECTION POINT -->
</Engine>
The code is deployed into the folder tudom. The .html works fine, but
my callbacks dont work.
A snippet from my web.xml:
<servlet>
<servlet-name>StartService</servlet-name>
<servlet-class>tudom.start.server.StartServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>StartService</servlet-name>
<url-pattern>/tudom.start.Start/StartService</url-pattern>
</servlet-mapping>
When im changing the URL-Pattern to
<url-pattern>/tudom.start.Start/StartService</url-pattern>
the Servlet gets reachable, but this doesnt interest GWT, cause it
still tries to load /tudom.start.Start/StartService.
Could everyone help me? Im now searching some hours and cant find
anything. Hope you can help me.
Greetings

Yes - you always need to have a default webapp to handle requests that do not match other webapp paths.

Though that will work, it may be surprising for a Tomcat admin, who
expects that the "localhost" vhost will point to "webapps" and not a
directory within it. Looking at your filesystem, I would expect webapps
deployed as /localhost and /tudor instead of what's really going on. Of
course, one should always read the server.xml, but it will certainly be
surprising to someone new.

Yes: you should have a ROOT webapp for each of your vhosts unless you
don't care to serve anything at the root (/) level.
> There (webapps/tudom/ROOT/) i deployed my files. Dont know why, but its working.
> Is it regular that i will need a ROOT-directory in my app-base?
Unless you want to deploy to http://srv2.tudom.de/tudom/index.html,
you'll need to have your webapp called ROOT: those are the rules.

Hey Christopher,
i got it working... i changed the host-entry and set the correct
CATALINA_HOME and CATALINA_BASE.
Both were not set correctly.
Now i set the following in server.xml:
for localhost
appBase="webapps/localhost/"
for srv2.tudom.de
appBase="webapps/tudom/"
after that i saw in the localhost directory that i will need a ROOT
directory in webapps/tudom.
There (webapps/tudom/ROOT/) i deployed my files. Dont know why, but its working.
Is it regular that i will need a ROOT-directory in my app-base?
Thank you for your great help!

Was that set to something else, earlier? /usr/share/tomcat6 looks like
the CATALINA_HOME for a package-managed version of Tomcat. If that's the
case, stuff could be anywhere.
Do you have a "webapps" directory anywhere? Your default <Host> is set
to appBase="webapps" and your /other/ <Host> is set to appBase="tudom".
Since these settings aren't fully-qualified, they will be relative to
the CATALINA_BASE setting (which is the same as CATALINA_HOME in a
standard install, but might be different depending on how your package
manager has laid things out).

Works for me:
$ host srv2.tudom.de
srv2.tudom.de A 109.239.60.41
Did you mean that you can't reach your webapps?
I suspect that your webapp isn't placed into the correct location. You
said that you can get to it, somehow. Is there a URL that responds with
a 200 response that Tomcat serves? If so, what is it?
(By the way, offering someone you don't know shell access on your server
is a really bad idea.)

Sorry for my stupidity.
Now $CATALINA_HOME is setted to "/usr/share/tomcat6".
There i can find "bin, lib, webapps". But now srv2.tudom.de is not
resolvable.
Any ideas?

When i am entering the $CATALINA_HOME directory in the shell with cd
$CATALINA_HOME
There is nothing else then there is nothing. cd $CATALINA_HOME/bin
redirects me into the bin folder.

Post your complete server.xml, with comments removed and passwords obfuscated. There's a strong possibility you've broken it.

Re: vhost - servlets not available
Posted by Johannes Stein <jo...@googlemail.com>.
Firebug says that the call is going to: /tudom.start.Start/StartService
And thats correct. Its also mapped correctly....
<servlet>
<servlet-name>StartService</servlet-name>
<servlet-class>tudom.start.server.StartServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>StartService</servlet-name>
<url-pattern>/tudom.start.Start/StartService</url-pattern>
</servlet-mapping>
But it isnt still reachable. Do you have any idea?

Okay, that can certainly cause problems if you introduce a new vhost and
don't use it properly. I'm not saying that's the problem, here... just
mentioning that if all you did was introduce another vhost, that's the
only thing I can think of.

It looks like the problematic request is for this URL:
http://srv2.tudom.de/tudom.start.Start/StartService
This will match your "srv2.tudom.de" domain, but probably will not match
your webapp's deployment path, which is /tudom. I would have expected
the URL to be:
http://srv2.tudom.de/tudom/tudom.start.Start/StartService
I even get a 404 when I access this. Can you verify your configuration
again? Post as much of your config as you can.

Oh, i made a mistake. When im changing the url-pattern in the
servlet-mapping to <url-pattern>/StartService</url-pattern> the
servlet will be avaible.
If i use the default config of gwt which sets:
<url-pattern>/tudom.start.Start/StartService</url-pattern> the Servlet
will not be available.

The files are on the same hast. I call directly the same vhost.

Thanks for using the standard deployment mechanism! So many people want
to edit server.xml for some reason.
BTW, 6.0.18 is really quite ancient. You should seriously consider
upgrading. 6.0.30 was released today... seems like an auspicious occasion.

Aren't those the same URL?
What is the full URL that GWT is trying to access -- including server
name? I suspect that the introduction of the VHOST has exposed a flaw in
the URL building in your GWT interface's URLs.
Are you trying to call one VHOST from a page hosted by another VHOST?
Are there any <BASE> elements in your web page that might be affecting
things?
It might be helpful to use a protocol sniffer like firebug,
LiveHTTPHeaders, iehttpheader, fiddler, etc. to see what URL your GWT
app is really trying to hit.
