The Tomcat server adapter differs from the generic ones in the level of
integration with the server, which is why it is coded very differently.
For example, if you change a JSP, the Tomcat server adapter can
publish just the JSP and you can display the new version in your
browser. With the generic server adapters, the WAR file gets rebuilt
and redeployed to the server. You will have to wait for the web
application to restart before you can display the changed JSP.
Cheers,
Larry

Thanks, Larry
but AFAIK, almost all main stream web servers support this kind of hot-deployment, like JBoss, Weblogic, did i miss any thing?
for the web server that support hot-deployment, the jst.tomcat way may be much better than generic.server
if we just focus on publishing, as we can get the publishing kind: INCREMENTAL, or FULL, i think maybe we can use antPublisher for FULL PUBLISHING (just what GenericServerBehaviour do), and define an abstract "doIncrementalPublishing" for INCREMENTAL PUBLISHING,
WDYT?
here just some thought, you know, I'm just going to extend JST to add some "Remote" serverTypes, that means, i will deploy web applications to the web server on remote box like Linux.
Thanks

The non-generic server adapters available from JBoss and Weblogic
already support this.

I think the point of the core code of the generic server adapter was to
keep the requirements on the server to a minimum. Any server that can
auto-deploy a war file copied to a certain directory can be supported.
The server adapter only needs to "understand" enough about the server to
start and stop it. Providing better integration with the server likely
means incorporating more "understanding" about the server, which also
means it's no longer "generic". This exercise has been left to the
third party server adapters.

Sounds fine. I think this has been on the to-do list for a while in
WTP, but I'm not sure how much progress has been made. I believe some
third party server adapters already support remote servers.
