thanks for your response galliv,
yes.. that i mean,, i can call method sayHello(),,
if the coolplugin package not exported to jar.
but how do i can access method sayHello()
while the code just like this..
PluginManager pm = PluginManagerFactory.createPluginManager();
pm.addPluginsFrom(new File("plugins/").toURI());
Thanks
