[news.eclipse.webtools] Glassfish Publishing Issue

[Chris <chrisjames64@xxxxxxxxxxxxx>]

This may belong with the Sun Glassfish team, but in case anyone knows 
the answer...

I have an EAR project in Eclipse containing a Dynamic Web Module and a 
Java Module, the latter containing supporting JPA code for the Web module.

The first time I publish to the server, everything works fine. However, 
if I modify anything while the server is running, Eclipse attempts to 
publish the application again and fails saying that the Java module's 
jar file is locked.

If I stop the server, start it and do a manual publish, it fails in the 
same way. If I stop the server and just click the publish button, 
(without starting the server first), it again fails in the same way.

The only way, I can republish is to stop the server and delete the 
application from the...
    C:\glassfishv3\glassfish\domains\domain1\eclipseApps
folder and then publish it again, which is driving me crazy.

So, is this just a classloader issue within glassfish? Is there a cure?

Thanks in advance for any help.
Cheers
Chris
