Changing the Default webapp

[Nick Fielding]

Dear Tomcat experts,

I've been trying to figure out how to change the default webapp in
Tomcat 6.0.18 from 'ROOT' to 'uPortal'. I want it such that, when a user
enters http://www.myportal.ac.uk/ into their browser they get uPortal
rather than the default out-of-the-box Tomcat landing page. Currently,
to get uPortal, a user has to enter: http://www.myportal.ac.uk/uPortal .

        - I've tried deleting the 'webapps/ROOT' webapp and creating a
symlink called 'ROOT' to link to 'webapps/uPortal'. This works, however,
I suspect the webapp is being initialised twice, once as ROOT and the
other as uPortal. This is obviously not great.

        - I could do an apache URI rewrite for '/' => '/uPortal/'. But
this would still result in '/uPortal/' appearing in the users address
bar.

        - The uPortal.war could be renamed to ROOT.war, however, I would
rather much prefer to keep uPortal in the 'uPortal' webapp directory.

        - I'd like to keep Tomcat's auto deploy functionality.


So, considering the points above, does anyone know a way of changing the
default webapp for Tomcat?


Many Thanks,
Nick

It is not possible to meet all of the above requirements. Which one of:
- autoDeploy
- no rename
- WAR kept webapps dir

are you prepared to drop?

Thanks for your reply Mark.

I feared this might be the case. I'm thinking deploying uPortal into the ROOT webapp might be our best option.

Thanks again,

numerous previous threads on the issue).

1) stop Tomcat
2) make a copy of webapps/ROOT, just in case you want later to revert
3) delete ROOT, and whatever is below it
4) rename webapps/uPortal to webapps/ROOT (or uPortal.war to ROOT.war)
5) restart Tomcat

That's not possible.  Ok, it's probably possible, but would be confusing.

That's not a problem.  But it's kind of inefficient for a production
server, as it requires Tomcat to come and check from time to time if
anything in /webapps has changed.
