Subject [jira] Resolved: (GERONIMODEVTOOLS-580) Servlet/JSP update forces a complete redeploy of a WAR

Tim McConnell resolved GERONIMODEVTOOLS-580.
--------------------------------------------

       Resolution: Fixed
    Fix Version/s: 2.1.5

HI Delos, thanks very much for this patch. It is a very good piece of work !! In my test workspace
with 2 web application projects it normally takes 20-25 seconds to redeploy both applications
when I modify JSP files in them. With your enhancement it now takes last then 2 seconds --
very impressive. 

With the recommended changes I asked for I committed it to both trunk (797732) and 2.1.5 (797733).
Finally, even though I'm resolving the issue you might want to consider a couple improvements.


1. See if you can get it to work for Jetty
2. Your message dialog to remind the user to ensure that the JSP compiler is enabled in development
mode is useful, but since you already know the installation directory of the server you could
easily read the necessary configuration file to see if that parameter is enabled or not. If
it is enabled there is no need to display the message dialog; if it's not enabled, you might
present instead a dialog with Yes and No buttons specifying whether the GEP should update
it on their behalf.

> I've had several users comment to me that application development with GEP is not as
fast as it should be. Basic scenario is create an application, deploy, test, update, test,
update, etc... IIUC, for each update, GEP is repackaging the WAR and running a redeploy. Repackaging/redeploy
can take some time (for large apps > 30 seconds). IIUC, we could be updating the appropriate
JSP/Servlet classes directly and greatly improving this behavior. I don't know how this works,
however. Anybody interested in looking at this? I'd like to see this improved in 2.2. If it's
something that could be fixed in 2.1.x, that would be great. But that might depend on how
extensive the changes are...
