>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 1.5.5
>         Environment: java version "1.6.0_30"
> Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
> Java HotSpot(TM) Client VM (build 20.5-b03, mixed mode, sharing)
>            Reporter: bernard

> How to reproduce:
> - Create a 1.5.5 quickstart
> - deploy it on the GlassFish server with directory deployment (I use NetBeans which is easy)
> - open the application in the browser
> - undeploy the application
> - try to execute the maven clean goal or try to delete the target dir
> Error in GlassFish log:
> Unable to delete file WEB-INF\lib\wicket-core-1.5.5.jar
> I first thought that this was a GlassFish issue such as:
> http://java.net/jira/browse/GLASSFISH-17339
> To eliminate that, I added glassfish\modules\war-util.jar to the project and wrote code to let GlassFish close all jar files:
> In the Application class:
>     @Override
>     public void onDestroy() {
>         super.onDestroy();
>         ClassLoader parentClassLoader = this.getClass().getClassLoader();
>         ClassLoader classLoader;
>         do{
>             classLoader = parentClassLoader; 
>             if(classLoader instanceof WebappClassLoader){
>                 WebappClassLoader glassFishLoader = (WebappClassLoader)classLoader;
>                 glassFishLoader.closeJARs(true);
>                 break;
>             }
>             parentClassLoader = classLoader.getParent();
>         }while(parentClassLoader != classLoader && parentClassLoader != null);
>         
>     }
> 	
> but this did not fix the problem.
