Virtual Host and dynamic webapp reloading

2007-09-25 Thread Daniel M Garland 

Hello,

I have a virtual host configured on my Tomcat 5.5.20 cluster installation.

In my server.xml, I have

autoDeploy="true">


And yet if I copy in a new war file (I'm using ant's deploy task) I 
don't see any changes to my webapp. If I look at the individual server's 
webapp via the manager application, I see the changes; but I don't see 
any changes by looking at the virtual host address until I restart Tomcat.


Why?

Thanks in advance.

remove the context defs from server.xml and put them in
META-INF/context.xml, which is a dir/file inside your webapp.

this method of defining contexts is not encouraged, because you have to
restart the server to reload the config, amongst other reasons.

the default web app is called ROOT.war, your other one would be
asmalljspapp.war. put both files in the appBase dir.

when it unpacks, it'll drop the contexts like so:

appBase/ROOT/META-INF/context.xml
appBase/asmalljspapp/META-INF/context.xml

i strongly recommend that you have a read of the Context config stuff in
the docs.  you'll need to set reloadable="true".

One other problem: docBase must point to the same directory as appBase.

Re: Virtual Host and dynamic webapp reloading

2007-09-26 Thread Daniel M Garland 
I've gotta say I've had a miserable time with this one. I've tried 
nearly permutation of configurations in the Tomcat documentation and 
nothing seems to work; either I get the default host or a white blank 
screen.


What I need is for www.mydomain.com to host mywebapp on the default path 
and anotherapp on path /anotherapp


If I have this setup in server.xml, everything works:

...

  
  
...

However, to get the dynamic webapp reloading I've been recommended to 
move my  elements out of server.xml. As I am running muliple 
virtual hosts I understand that I cannot use conf/context.xml because 
this applies to all hosts.

So I have tried each of the following, without success:
- creating a conf/Catalina/mydomain.com/mywebapp.xml
- creating a conf/Catalina/mydomain.com/ROOT.xml
- creating a conf/Catalina/mydomain.com/context.xml
- creating a conf/Catalina/mydomain.com/context.xml.default
- creating a META-INF/context.xml in the web app (although I'd prefer to 
sort this out within Tomcat anyway)


I've also tried several variations on the docBase: ".", "mywebapp", the 
absolute path, the absolute path to the .war file...


I mean, why wouldn't this work?
in conf/server.xml:

in conf/Catalina/mydomain.com/mywebapp.xml:


Any ideas on how I can achieve the equivalent of my working server.xml 
with nested Contexts in some other file?

Dan Garland

That docBase="." is going to give you nothing but trouble. Why can't you
just do this:

1. Start with a clean install of Tomcat.
2. Modify CATALINA_HOME/conf/server.xml to include your clustering
   configuration.
3. Drop ROOT.war into CATALINA_HOME/webapps
4. Drop anotherapp.was into CATALINA_HOME/webapps
5. Start up Tomcat

This should work. You don't need any crazy configuration. Your 
configuration should be in META-INF/context.xml in each of your WAR files.

Tell me more about your virtual host configuration. Do you actually need
Tomcat to understand your virtual hosts? Or, is it sufficient to have
all applications available to all host names?

Re: Virtual Host and dynamic webapp reloading

2007-09-26 Thread Daniel M Garland 

Hi Chris,

I have three virtual hosts that I want to have hosting a webapp on the 
default path. Each host has a few aliases for subdomains etc. So I don't 
really want to have ROOT.war in CATALINA_HOME/webapps, partly because I 
want to keep the manager app and partly because I would have a ROOT.war 
files for each host, so I think you're saying


CATALINA_HOME/webapps
 /myapp1/ROOT
 /myapp2/ROOT
 /myapp3/ROOT

So I would've thought that I'd have the appBase of each host be 
myappX/ROOT, but what would the corresponding context.xml be? Does it 
actually work holding this file in /conf, I'm not sure about having this 
in the webapp, is it standard to have a META-INF/context.xml or is that 
a Tomcat thing?


Thanks for all the input so far folks

You're almost certainly mixing the remnants of the various configuration

Yes, as I said before...

1. Remove the context definitions from the server.xml.
2. You must not define multiple Contexts in conf/context.xml.
3. Do not define conf/Catalina/mydomain.com/.xml.
4. Do not use the path or docBase outside of server.xml.
5. Start with a fresh configuration, to ensure you aren't mixing configs
in your rush to solve the problem.
6. Include a META-INF/context.xml with your context config in the WAR.
Check that it's there by unzipping a copy of the WAR.
7. Don't forget to include the reloadable="true" settings in the context.
8. Just install the ROOT war, then configure the remaining app(s). One
thing at a time.  Tomcat will auto-deploy and copy the configs into
conf/Catalina/host/




Place the default app like so:

your/apps/ROOT.war


If this doesn't deploy/start up, check your log files and look for
errors in catalina.out and any app-local logs.

Post the file system layout after deployment, the actual context you
deployed in the war, and your current server.xml.

You can deploy the manager app even when there is a ROOT application
deployed.

Well, I didn't say that, but if I had said something like that, I would
have suggested:

CATALINA_HOME/webapps (contains nothing)

VIRTUAL_HOME/www.domain1.com[/webapps]
ROOT
myapp1
myapp2
...

VIRTUAL_HOME/www.domain2.com[/webapps]
ROOT
myapp1
myapp2
...

You will need separate  elements in your server.xml file. The
"appBase" for each of these should be VIRTUAL_HOST/www.[whatever].com,
or whatever you choose to be your directory layout.

If you are deploying all the same applications on all virtual hosts,
then you can ignore the whole virtual host concept and just use a
default host to serve everything regardless of the hostname.

> So I would've thought that I'd have the appBase of each host be 
> myappX/ROOT

No, no no. The "appBase" tells Tomcat where to look for deployable
applications, not the directory where /index.html should be found. This
is NOT the same thing as DocumentRoot in Apache httpd. Shave off the
ROOT and you've got yourself a decent configuration. If there is a
directory called ROOT (or a WAR file called ROOT.war) in the appBase
directory, /that/ application will be used as the one that is deployed
with no context path (i.e on / instead of /myapp).

> but what would the corresponding context.xml be?

The context.xml file should not contain any path information whatsoever.
All you need is JNDI resources, realm configuration and stuff like that.
This is a perfectly good context.xml file:



You don't need anything else unless your application needs special
configuration. If you don't have anything in your context.xml file, you
can even leave it out, since Tomcat will give you the default deployment
configuration (which is an empty config).

This is a Tomcat thing only.

Re: Virtual Host and dynamic webapp reloading [SOLVED]

2007-09-27 Thread Daniel M Garland 
Thanks to all for your responses and advice, from this I have now 
addressed the problem by using an alternative configuration. For the 
record heres what I did:


- I ended up creating a completely different folder for my webapps. I 
created subdirectories for each virtual host, rather than having all my 
virtual host's web applications inside $CATALINA_HOME/webapps, and set 
the appBase in server.xml's  element to match this.
- I had my ant script generate a ROOT.war instead of the project name 
and dumped this .war in my new appBase/domain/ directory.

- I set unpackWars and autoDeploy to true on each Host
- I created a META-INF/context.xml in my web app (as I needed to do some 
config on the context)


Now whenever I drop a new web app in using the catalina ant deploy task 
the changes are reflected. So I suppose the punchline is don't bung all 
your webapps in the default folder and try to use  elements, 
but break them into seperate folders, and use ROOT.war if you want to 
host off the default context ("/").


thanks everyone!

Hello,

I have a virtual host configured on my Tomcat 5.5.20 cluster installation.

In my server.xml, I have

autoDeploy="true">


And yet if I copy in a new war file (I'm using ant's deploy task) I 
don't see any changes to my webapp. If I look at the individual server's 
webapp via the manager application, I see the changes; but I don't see 
any changes by looking at the virtual host address until I restart Tomcat.


Why?

Thanks in advance.
