Sorry - should also add - I'm running on a 1.3 snapshot and the relevant
block of code in wicket is:
class ContextParamWebApplicationFactory lines 61 to 81
protected WebApplication createApplication(final String
applicationClassName)
{
try
{
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
if (loader == null)
{
loader = getClass().getClassLoader();
}
final Class applicationClass =
loader.loadClass(applicationClassName);
if
(WebApplication.class.isAssignableFrom(applicationClass))
{
// Construct WebApplication subclass
return
(WebApplication)applicationClass.newInstance();
}
else
{
throw new WicketRuntimeException("Application
class " +
applicationClassName
+ " must be a subclass of
WebApplication");
}
}
