[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-1300) Standardize mechanism for setting defaultClassLoader

Standardize mechanism for setting defaultClassLoader ---------------------------------------------------- Key: JBCACHE-1300 URL: http://jira.jboss.com/jira/browse/JBCACHE-1300 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Brian Stansberry Assigned To: Manik Surtani Priority: Minor Fix For: 2.1.0.GA Right now the default classloader used by the cache's marshaller is fixed to CacheImpl.class.getClassLoader(), with no clear mechanism for users to change that. In the Hibernate/JBC testsuite I did the following: public class CustomClassLoaderCacheFactory<K, V> extends DefaultCacheFactory<K, V> { private ClassLoader customClassLoader; public CustomClassLoaderCacheFactory(ClassLoader customClassLoader) { this.customClassLoader = customClassLoader; } @Override protected void bootstrap(CacheImpl cache, CacheSPI spi, Configuration configuration) { super.bootstrap(cache, spi, configuration); // Replace the deployerClassLoader componentRegistry.registerComponent("deployerClassLoader", customClassLoader, ClassLoader.class); } } That works, but seems fragile, e.g .if how super.bootstrap() works changes it could break. It would be better to have something more standardized; perhaps a property on DefaultCacheFactory that could be set, w/ a guarantee in the DefaultCacheFactory javadoc that it will be used if set. Or something else. :-) Manik, not sure where you're planning to go w/ defaultClassLoader; I'm just throwing this request out there to get the topic in JIRA. OT: doing this is great in testsuites, as you can use it to configure a default classloader that can't see some of your test classes, and thus test marshalling.
