How to deploy my webapp as root context webapp without tomcat loading it twice?
Hi,
Scenario:
I've a webapplication in my tomcat4 installation, called myWebapp.
I've configured it to be my root webapplication since I want users to
be able to access it using the url: "http:<host>:<port>". Here's a
snippet of my server.xml:
<!-- Define the default virtual host -->
<Host name="localhost" debug="0" appBase="webapps" unpackWARs="true"
autoDeploy="false" liveDeploy="false">
<!-- Tomcat Root Context -->
<Context path="" docBase="myWebapp" debug="0" reloadable="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_myWebapp_log." suffix=".txt"
timestamp="true"/>
</Context>
myWebapp has a init servlet which is loaded on startup. Besides doing
other things like instantiating db connection pool, this servlet
configures the log4j for the application logging.
Issue:
When I start the tomcat server, I find, through logs of the application (and
of log4j), that the init servlet is executed twice.
Essentially, the webapp is loaded twice. This creates a problem with
myWebapp since the logger is configured twice (resulting in
cross-locks and hence Rolling fails).
Question:
I want to have myWebapp as the root context webapp in my tomcat
server. And I don't want to rename it to "ROOT". Is there a way by
which I can avoid tomcat from loading myWebapp twice?
Thanks in advance,
Vivek.

Sorry Mark, but one question to you since you've suggested the option
of moving the webapp outside of appBase.
I've kept myWebapp at ${CATALINA.HOME}/myWebapp and given this path in
server.xml for the root context. Is that the correct way to do it? Is
there anything in my webapp that I need to take care of when I do
this?

That's what I did, I submitted this problem a month ago or so and came
up with this solution, asking if there weren't any better ones.
Renaming the webapp dir to ROOT is a nono so far, so I defined a
nonexisting appBase and put an absolute path in <Context>. It works,
but it's ugly, for sure :(
I wonder whether creating Catalina/<hostname here>/ROOT.xml with the
appropriate <Context> would work...
(BTW this is using tomcat 5.0.x, x>=27)

My hunch is that you won't get a definitive answer to this question
in this group :-/
I *think* you need to do all these:
* maintain an empty appBase directory
* leave autoDeploy alone (there's nothing for it to deploy)
* set docBase in Context to an absolute path to your app

Like I mentioned in my problem statement:
I don't want to move my application into ROOT folder or rename it to ROOT.
And unlike as you said Mark, putting autoDeploy=false doesn't help in this case.
Is this (loading a webapp twice if the context path and the docBase
path is different) a feature of Tomcat? Can't this be turned off?

Since this was brought up..
I moved my default ROOT folder out my webapps directory ( to a temp
dir on my server ), because I wanted a different app to the be the
default application. So I moved my application's direcotry to
webapps/ROOT and everything has been working fine. Is there anything
"wrong" with doing it that way ? Like I said, everything has been
working great so far, which has been about 3 months.
Thanks,
Joe

Options:
- Don't put it in the appbase directory.
- Turn off autoDeploy
- Live with renaming it to ROOT
