Hi,
We are trying to use Chain Of Responsibility pattern in the server side. We
have defined our chain+commands in an xml and are parsing it via ConfigParser.
But we face a problem with getting Catalog via
CatalogFactoryBase.getInstance().getCatalog(catalogName) call.Looks like it has
got some ClassLoader specific loading. So if we have initialized in some web
context, the Catalog is not present in other context - different ClassLoader.
Is there anyway we can remove this ClassLoader level dependency or is there any
other way of loading the chain configuration for server side usage?
/** * <p>Return the singleton {@link CatalogFactory} instance
* for the relevant <code>ClassLoader</code>. For applications
* that use a thread context class loader (such as web applications
* running inside a servet container), this will return a separate
* instance for each application, even if this class is loaded from
* a shared parent class loader.</p>
*
* @return the per-application singleton instance of {@link CatalogFactory}
*/
public static CatalogFactory getInstance() {
CatalogFactory factory = null;
ClassLoader cl = getClassLoader();
synchronized (factories) {
factory = (CatalogFactory) factories.get(cl);
if (factory == null) {
factory = new CatalogFactoryBase();
factories.put(cl, factory);
}
}
return factory;
}
Regards,
Jagan
