Hi,

I am trying to solve a problem that I am having with WTP publishing. I
use a library in my web application, which keeps one of the resource
files locked when running on an application server. If I deploy my web
application to Tomcat, the application will run fine. However, every
time I edit the locked resource file in the IDE when the application is
already running, WTP displays:

"Error copying file to (my workspace
location)\.metadata.plugins\org.eclipse.wst.server.core\tmp0 \webapps\...
Error deleting:
(my workspace
location)\.metadata.plugins\org.eclipse.wst.server.core\tmp0 \webapps\... "

Is that a way I can workaround this? The file is locked for delete but
I can overwrite the file...

I tried the antiResourceLocking flag for Tomcat, but I am hoping to find
a solution that works for all servers and still allow me to make
modifications to the file.

For example, if there's a way I can hook up to an extension point such
that I can stop/restart the web application during publish, I'll be able
to release the lock on the resource files and overwrite them...

Thanks,
ap

My understanding is that this is a Windows issue, so outside of
replacing your OS, I'm not sure what can be done beyond what the
application offers. I believe that Tomcat achieves the "anti-locking"
by making copies so the original remains writable while the server uses
the copy. Obviously, this impacts startup and deployment performance.

Cheers,
Larry

Thanks, Larry. I am wondering, if it's not possible to fully fix this
issue on Windows, whether or not there's a way I can customize the
publishing logic, such that I can tell the server adapters to restart
the application as opposed to publishing the modified resource? This
behavior is similar to modification to any resources in the WEB-INF
folder, except I would like to be able to extend the list of items that
will trigger a restart...

Thanks,
ap

The issue should be fixable, but what can be easily done with the
current code base, I'm not sure. There is no "list" that I'm aware of.
