META-INF/context.xml and deploy issue
Hello,
I'm facing an issue with tomcat 6. In order to setup a JDNI, we added a
context.xml file to our application (XWiki) in the already-deployed
folder webapps/xwiki/META-INF/ and configured the existing
webapps/xwiki/WEB-INF/web.xml accordingly.
update of web.xml triggered the app reload which is expected.
At this point I wanted to adjust the database configuration, ie by
modifying webapps/xwiki/META-INF/context.xml. When I do this the changes
are not taken into account because the file Catalina/localhost/xwiki.xml
is not overwritten by Tomcat.
The solution that came into my mind has been to force Tomcat to update
the file bt deleting Catalina/localhost/xwiki.xml - which has indeed
make Tomcat undeploy and deploy the app again.
Here are my questions:
1) As there is no war file involved, what does "undeploy" and "deploy"
means ? What is being done exactly ?
2) Why is the file webapps/xwiki/WEB-INF/web.xml is missing, after I
remove xwiki.xml and the app is redeployed ? (no web.xml = no deployment
so at the moment I have to manually restore a backup of this file)
Thanks !

There are lots of nasty edge cases in the deployment process. This has
been cleaned up in 7.0.x and 8.0.x but not in 6.0.x.
See
http://tomcat.apache.org/tomcat-8.0-doc/config/automatic-deployment.html
for the behaviour in 8.0.x.

undeloy - means stop the app and remove any references to it from
CATALINA_BASE/conf/<engine>/<host> and CATALINA_BASE/webapps
deploy - means tell Tomcat about the app and start it. This may reesult
in files being copied to CATALINA_BASE/conf/<engine>/<host> and/or
CATALINA_BASE/webapps

No idea.

web.xml is not required. The app will still be deployed. It just might
not function that well.
