4. My understanding is that I should be able to point the install and refresh tasks at the .war file for my app, and it'll install/reload as requested. The list and remove tasks work fine at this point.

My Issues:

[install] OK - Installed application at context path /appfuse

Remove: Doesn't seem to work, but it actually does. Here's what Ant reports:

[remove] FAIL - Encountered exception java.io.IOException: java.lang.NullPointerException

[remove] FAIL - No context exists for path /appfuse

Reload: Doesn't work:

[reload] FAIL - Reload not supported on WAR deployed at path /cct

My Thoughts

• The problem might be that I'm not pointing to a build/appfuse directory that contains an already intact webapp directory structure - instead I'm pointing to a real .war file. My context has path="/appfuse" rather than path="/appfuse.war", so I wonder if that matters.
• Reload seems pointless to me, I still have to deploy (copy files to $CATALINA_HOME/webapp) to Tomcat, and when I do this with Ant's <copy> task, Tomcat reloads the app automagically.
• Using these tasks seems like a waste of time - especially since I'm just replacing something that already works for me. Please, someone prove me wrong. And not with points and counterpoints - but by checking out AppFuse from CVS and submitting patches. ;-)

Install: Doesn't work.: Well, you need to specify the context XML file also (it's a separate deployment, so the existing one doesn't get picked up automatically). If the Context element is in server.xml, then it won't work.

Remove: Doesn't seem to work: I don't know about that one. Probably the fact that there a context file is causing trouble of some sort.

Reload: Doesn't work: You can't reload a WAR indeed (you undeploy it, and then redeploy it when it is updated; however, its content cannot change unless the WAR itself changes, that's why reloading has no meaning for a WAR). Webapp reloading is for automatic class change tracking. It doesn't prevent any manual reloading.

The behavior of the deployer and its related tasks will be more intuitive in TC 5, and more integrated with the auto deployer. the latest nightly has a lot of this stuff implemented http://cvs.apache.org/builds/jakarta-tomcat-5/nightly/jakarta-tomcat-5-bin-20030624.tar.gz. Note that both install and remove are now deprecated, replaced by deploy and undeploy.
