Exception in Tiles after Action modification..

[Franck Tranchant]

Hi

My current configuration is giving me headache since I'm forced to re-start my server every time a Action class is modified...
I'm developing a Struts+Tiles based web-application on Weblogic7.
Deployment is made using Ant.

Once my deployment target is launched, resources such as Images or JSP are succefully updated when I'm re-running my Application.
But, every time an Action class is modified, the execution fails...

Here is the log :

<Error> <HTTP> <101017> <[ServletContext(id=xxx,name=xxx,context-path=/xxx)] Root cause of ServletException

Looks like Tiles is involved, even if no modification in the tiles.xml was made...

Does anyone know how to walk around this problem ?
Thanx in advance.
