I don't see anything in the previous GBF code that allowed you to override the classloader (other than the metadata). anonymous wrote : However, now the underlying GenericBeanFactory will always use the loader of its KernelControllerContext to create the bean instance, so in the case outlined the wrong loader is used to create the bean. | This hasn't changed. All that changed is that this retrieval is now in a privileged block. Asking the controller context essentially asks the ClassLoaderMetaData if it has one (otherwise it uses the TCL), which will be coming from whatever you setup in the deployer.

This gives me better results although I am still seeing some failures. The ClassLoaderMetaData is also used to decide the classloader for other things, e.g. string conversion to classes so I don't think being able to specify a classloader on the GBF method is much help without rewriting all the metadata classes to also allow the classloader to be overridden.
