Hi Team,
i am developing one application it uses *"platonos plugin engine".* design is like : * server (intiates plugin engine) | |---- plugin 1 (dynamically deployed) |---- plugin 2* server accepts plugins, install them and manage their lifecycle. server maintain registry of services provided by plugins plugin register their *service classes* to server Note : service classes loaded by plugin class loader server loaded by system default class loader when any request come to server server identifies proper service class from registry and call method of plugin before calling it is doing * Thread.currentThread().setContextClassLoader(pluginClassLoader);* this works better for non custom objects. like standard JRE objects (Int, Long,String etc..) now my one plugin have one custom object which is visible in plugin class loader. (present in class path of plugin) but when it used Java *ObjectInputStream to deserialize* custom object protected Class<?> resolveClass(ObjectStreamClass desc) throws IOException, ClassNotFoundException { .... return Class.forName(name, false, *latestUserDefinedLoader()*); .... } * latestUserDefinedLoader() *causes class not found exception. *latestUserDefinedLoader() return server class loader (IN DEBUG VIEW)* actually it should use plugin class loader but this same scenario works properly in Tomact and other webservers with different classloaders. * i am surprised how to change behaviour of latestUserDefinedLoader()* ?? do i need to change classloader for some security or permission or something else pls help ??? awaiting for ur reply !!!! *Regards* *Dhruv Patel* * *
