Hi Martin,
"Here it is not very clear what exactly is the change. One has to diff it
agaisnt the original code to see what you have added/removed. "
I added following:
clazz = Class.forName(type, false, this.getClass().getClassLoader());
if (clazz == null) {
throw Exception...
I need to force the framework to use the application classloader...different
to currentThread's classloader...
"You can use custom IClassResolver, no ?
One that does whatever WebLogic needs to resolve the class and don't break
or return null. "
Unfortunatelly Wicket's classResolver won't help you, because we've got a
problem during HTTP session serialization which isn't Wicket's application
thread....
if (Application.exists())
{
resolved = (Class<T>)Application.get()
.getApplicationSettings()
.getClassResolver()
.resolveClass(className);
}
This is skipped...and Wicket goes here...
if (resolved == null)
{
resolved =
(Class<T>)Class.forName(className, false,
Thread.currentThread() .getContextClassLoader());
}
which ends with ClassNotFoundException when having @SpringBean in WebSession
and If WLS doesn't have ChangeAware classloader bindided to thread.
Suggested changes:
1) Either to change:
static class ProxyReplacement implements IClusterable {
private static final long serialVersionUID = 1L;
private final IProxyTargetLocator locator;
private final String type;
public ProxyReplacement(String type, IProxyTargetLocator locator) {
this.type = type;
this.locator = locator;
}
private Object readResolve() throws ObjectStreamException {
Class<?> clazz = WicketObjects.resolveClass(this.type);
if (clazz == null) {
clazz = Class.forName(type, false,
this.getClass().getClassLoader());
if (clazz == null) {
ClassNotFoundException cause = new
ClassNotFoundException("Could not resolve type ["
+ this.type + "] with the currently configured
org.apache.wicket.application.IClassResolver");
throw new WicketRuntimeException(cause);
}
} else {
return LazyInitProxyFactory.createProxy(clazz,
this.locator);
}
}
}
2) Another possible fix (WicketObjects):
public static <T> Class<T> resolveClass(final String className)
{
Class<T> resolved = null;
try
{
if (Application.exists())
{
resolved = (Class<T>)Application.get()
.getApplicationSettings()
.getClassResolver()
.resolveClass(className);
}
if (resolved == null)
{
resolved = (Class<T>)Class.forName(className,
false,
WicketObjects.class.getClassLoader());
}
}
catch (ClassNotFoundException cnfx)
{
log.warn("Could not resolve class [" + className + "]",
cnfx);
}
return resolved;
}
Both changes have the same effect...Please would you be willing to propagate
this into the patch?
