Kill me for that ugly hack:
public class UglyCrackHoreBitchMFListener implements ServletContextListener
{
private static final Logger log = LoggerFactory.getLogger(ClearJVMCacheListener.class);
@Override
public void contextInitialized(ServletContextEvent sce)
{
try
{
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Class<?> juc = cl.loadClass("sun.net.www.protocol.jar.JarURLConnection");
Field field = juc.getDeclaredField("factory");
field.setAccessible(true);
Object jff = field.get(null); // JarFileFactory
Field cacheField = jff.getClass().getDeclaredField("fileCache");
cacheField.setAccessible(true);
cacheField.set(null, new HashMap<Object, Object>());
cacheField = jff.getClass().getDeclaredField("urlCache");
cacheField.setAccessible(true);
cacheField.set(null, new HashMap<Object, Object>());
}
catch (Exception e)
{
// unlucky -- different JVM, SecurityManager or whatever blocked you effort
log.error(e.getMessage(), e);
}
}
@Override
public void contextDestroyed(ServletContextEvent sce)
{
}
}

> Wicket fails to read html markup from jar after updating and redeploying in jetty

> Key: WICKET-2826
> URL: https://issues.apache.org/jira/browse/WICKET-2826
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.7
> Environment: Linux, jetty 6 using context deployer
> Reporter: Adrian Sandor
> Assignee: Igor Vaynberg
> Fix For: 1.4.11
>
> Attachments: jetty.xml, simplewicket.xml, simplewicket.zip

> I wrote a web application and packaged the main code and html markup files into a jar. I deployed it in jetty using the "extracted war" folder structure and a context descriptor. The application worked fine.
> Then I made a minor change in an html file, rebuilt the jar, copied it over the old one in jetty and touched the descriptor to reload the context. Then when trying to access the application in the browser, I got errors like:
> org.apache.wicket.markup.MarkupCache - Unable to find markup from jar:file:/path/to/jar!/path/to/html
