Heh... Container stability during development for a single user is hard
enough than to have to worry about what your other lab students are
doing at the same time.
The general get-out when you first find a problem that isn't an obvious
programming error is to restart the container and re-test the situation.
Maybe you'd be better off teaching students how to use Eclipse and
manage their own Tomcat instance from within it. But to use Eclipse
you'd need PCs of half decent spec with a little more RAM on board.
Sorry I don't have an answer to your request, and whatever I do say has
more bearing on TC 5.5.x than 5.0.x. But my understanding is that there
is a single deployment directory folder per virtual hostname.
So if you wanted to give each student/computer their own workspace maybe
you could setup DNS to point lab01host001.tomcat.mydomain.com to the
same IP address.
Then setup <Host> directives in conf/server.xml like:
<Host name="lab01host001.tomcat.mydomain.com"
appBase="/opt/website/lab01host001.tomcat.mydomain.com/tomcat/webapps"
workDir="/opt/website/lab01host001.tomcat.mydomain.com/tomcat/work"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
To setup each lab users workspace use:
mkdir /opt/website/lab01host001.tomcat.mydomain.com/tomcat
mkdir /opt/website/lab01host001.tomcat.mydomain.com/tomcat/work
mkdir /opt/website/lab01host001.tomcat.mydomain.com/tomcat/webapps
# chown the "work" folder to the same user the TC JVM instance runs as:
chown jakarta.jakarta
/opt/website/lab01host001.tomcat.mydomain.com/tomcat/work
chmod 775 /opt/website/lab01host001.tomcat.mydomain.com/tomcat/work
# chown the "webapps" folder to the same user as the student that is
allowed to deploy, but also give the TB JVM instalce group permission to
write too.
chown student0123.jakarta
/opt/website/lab01host001.tomcat.mydomain.com/tomcat/webapps
chmod 775 /opt/website/lab01host001.tomcat.mydomain.com/tomcat/webapps
# deploy your webapp and access as: http://lab01host001.tomcat.mydomain.com/
cp ROOT.war
/opt/website/lab01host001.tomcat.mydomain.com/tomcat/webapps/ROOT.war
# or under a context and access as:
http://lab01host001.tomcat.mydomain.com/student0123/
cp student0123.war
/opt/website/lab01host001.tomcat.mydomain.com/tomcat/webapps/student0123.war
# You may wish to create inside your WAR the file META-INF/context.xml
for any context specific parameters. See TC documentation.
You'd still need to give the students the ability to shutdown and
restart the container themselves, it really is a necessary requirement
to successfully develop with TC. More so if you are a student and don't
understand anything to begin with and need to learn from making as many
mistakes as possible.

Following the instructions of the documentation (for 5.0),
I found the topic 'User Web Applications' in the host container
documentation. The doc states:
'If a user home directory has been set up for a user named
craigmcc, then its contents will be visible from a client browser
by making a request to a URL like:'
which is the behaviour I get. I.e., it will only list the contents of
the directories and return files if selected. The doc then goes on:
'Successful use of this feature requires recognition of the
following considerations:
Each user web application will be deployed with characteristics
established by any DefaultContext element you have configured
for this Host.'
Which tells me that user applications are *deployed* - but how?
No matter what applictaion I put into the user's webapp directory
(given as attribute to the Listener tag), it is never deployed, but if I
put it into the webapp of the tomcat home, then it will be deployed.
The logs state:
catalina.out:
4-May-06 11:50:37 AM org.apache.catalina.startup.ContextConfig
applicationConfig()
INFO: Missing application web.xml, using defaults only
StandardEngine[Catalina].StandardHost[localhost].StandardContext[/~unilogon]
Okay, so where should this web.xml be put? Into the same directory given
in the directoryName attribute of the Listener tag?
and localhost_log.2006-05-04.txt:
2006-05-04 11:50:34 UserConfig[localhost]: UserConfig: Processing START
2006-05-04 11:50:34 UserConfig[localhost]: Deploying user web applications
2006-05-04 11:50:36 UserConfig[localhost]: Deploying web application for
user unilogon
which make me think all's ok, but it isn't.
What am I missing?
many thanks in advance, Robert
