OK, just found an old mail of you where you are talking about 2.0. When I read it I found out that some things are not in the current version on cvs. - No J2ME support. - No dependency injection (like injecting configuration). - No signed plugins. But the current engine now has better unload/reload during runtime but normally you want to restart the application when you want to update 1 or more plugins. I could add some code to support restart. I could add it as a shutdown hook in the JVM so just before the JVM is shutdown a new one could be started. Most of the code is simular to the old but it has been restructed into more packages so its not a full drop in replacement for the old one, but for the most part is should (and I hope) work like before. One thing I added is the Application class, my intension's with that was that it contains only the normal things most plugins need, the more internal stuff like loading/unloading/starting plugins are in the PluginEngine class. I also added code for supporting services. It almost works the same as for extensionpoints and extensions. <servicepoints> <servicepoint name="Printer" interface="test.Printer" /> </servicepoints> <services> <service uid="printerServicePlugin" name="Printer" class="MyPrinter" /> </services> The differents is that with extensionpoints and extensions, the extensionpoint plugin uses the extensions and with servicepoints and services any plugin can make use of the services thru the servicepoint. I think the threading stuff is out, I didn't have any issues with it at least. So there is still work to do, so I will continue to work on it.
