Re: Install Task and good use of ant tasks

[Jacob Kjome <ho...@visi.com>]

I like your idea for checking whether an app exists before undeploying.  I 
might start using that myself.  As far as the difference between install 
and deploy, deploy is persistent across server restarts as it physically 
modifies the server.xml and stores the .war file within tomcat's "work" 
directory structure.  The install task, on the other hand, only installs to 
memory.  It actually installs the app from wherver it currently exists on 
the file system rather than uploading it to Tomcat.  A restart of Tomcat 
will blow away any hints that the application was ever installed on the 
server.  This is very useful for development and doesn't cause your 
server.xml to become munged by the re-writing that is done when an app is 
deployed via the deploy task.

Hope that helps,

Jake
