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
> org.apache.wicket.util.resource.ResourceStreamNotFoundException: Resource
