I mean, how does Java decide which protocols are available? I run some code from inside Eclipse, and it works just fine. Then I run the same code from outside Eclipse, and I get ‘unknown protocol’ MalformedURLException. Probably it has to do with the code base, or something? Any hints would be helpful.
Thanks!
The work of resolving the protocol is done by the
URLStreamHandler, which are stored inURL.handlersby protocol in lowercase. The handler, in turn, is created by theURLStreamHandlerFactoryatURL.factory. Maybe eclipse is monkeying with that?Some of the URL constructors take stream handlers and you can set the factory with URL.setURLStreamHandlerFactory.
Here’s a web post about developing protocol handlers.
