File locations: EAR, WAR, XML datasource

[Daniel Pocock <daniel@readytechnology.co.uk>]

Hi,

Are there standard directory locations for the following types of files 
which are normally deployed to a J2EE container:

- EAR and WAR files

- XML datasource files

By default, containers like JBoss look inside their own directory 
structure (e.g. /opt/jboss/server/default/deploy) - however, they can be 
configured to look in a central location (e.g. /usr/share/java/deploy 
perhaps).  This would enable WAR files and EAR files to be packaged 
without worrying about whether the user will install Jonas, JBoss, 
Tomcat or something else.

I've looked in the Debian Java FAQ (EJB and Servlet sections) and also 
the Wiki (link below) and couldn't find an existing answer to this question.

http://wiki.debian.org/FileSetsAndLocations

Also, defining such a directory would probably mean we need to define 
some dependencies, such as `j2ee-war-container', and 
`j2ee-ejb-container'.  These dependencies would be satisfied by packages 
such as Tomcat, and could be used to ensure that two conflicting 
containers were not installed.

Regards,

Daniel
