Hello everyone
I'm trying to register a custom protocol handler with an eclipse rcp bundle
using the approach given in Chapter 11 of the OSGi Specification V4. The new
protocol handler should connect to a password protected http server using an
url string like "<username>:<password>@someurl". Therefore I define the new
protocol ahttp using the following URLStreamHandler.
public class ProtectedHttpURLStreamHandler
extends AbstractURLStreamHandlerService
{
public URLConnection openConnection (
URL url) throws IOException
{
// TODO: create a custom URLConnection which handles the following
URLConnection conn = null;
String user = null;
String passwd = null;
String enc = null;
if (url.getUserInfo () != null)
{
user = url.getUserInfo ().substring (0, url.getUserInfo ().indexOf
(":"));
passwd = url.getUserInfo ().substring (url.getUserInfo ().indexOf (":") +
1);
enc = new BASE64Encoder ().encode ((user + ":" + passwd).getBytes ());
}
String host = url.getHost ();
url = new URL ("http", host , url.getPath ());
System.out.println (url.toString ());
conn = url.openConnection ();
if (enc != null)
{
conn.setRequestProperty ("Authorization", "Basic " + enc);
}
//System.getProperties().put( "http.proxyAuthToken", enc );
return conn; }
}
In the activator of the rcp application I'm registering the protocol with
the following code
public void start(BundleContext context) throws Exception {
super.start(context);
Hashtable<String, String[]> properties = new Hashtable<String,
String[]> ();
properties.put (URLConstants.URL_HANDLER_PROTOCOL, new String[] {
"ahttp" });
context.registerService (URLStreamHandlerService.class.getName (),
new ProtectedHttpURLStreamHandler(), properties);
}
I need the custom protocol to connect to a password protected http codebase
for Jini (RMI). When I start the programm he first seems to find the custom
handler as I can see from debugging. He calls it several times. But the
suddenly I get the following exception. Important to me seems the
java.net.MalformedURLException: unknown protocol: ahttp. So suddenly he
seems to not find the handler anymore. The class the exception is coming
from is in another bundle so may there is a problem with the classloaders.
java.rmi.ServerException: RemoteException in server thread; nested exception
is:
java.rmi.UnmarshalException: unmarshalling method/arguments; nested
exception is:
java.net.MalformedURLException: unknown protocol: ahttp

Hi Christian,
Can you tell a bit more about the environment you're running under.
Also, if you can duplicate the problem in the debugger could you set a break
point on "java.net.MalformedURLException" to see if we can narrow down where
the exception is getting thrown from.

Hi,
Ok some more to the environment. My System is a Win XP Pro running Java
1.5.0_08. My Application is consists of an Eclipse 3.2.0 RCP Plugin and some
additional Equinox Bundles. And I'm running Jini 2.1 with the Outrigger
JavaSpace implementation.
What I wan't to reach is that Jini uses a password protected Apache2 as
codebase. On the Jini newsgroup I found out that I have to register a custom
URLHandler to handle the login data because the standard Java URL
implementation doesn't support urls like http://user:pass@someserver.
At the beginning the Application stops two times on a breakpoint in my
custom handler. But then I get the Exception thrown from where I try to
retrieve the JavaSpace.
public void discovered (
DiscoveryEvent anEvent)
{
synchronized (this)
{
if (proxy != null)
return;
}
ServiceRegistrar[] myRegs = anEvent.getRegistrars ();
for (int i = 0; i < myRegs.length; i++)
{
ServiceRegistrar myReg = myRegs[i];
Object myProxy = null;
try
{
myProxy = myReg.lookup (serviceTemplate);
if (myProxy != null)
{
signalGotProxy (myProxy);
break;
}
}
catch (RemoteException anRE)
{
System.err.println ("ServiceRegistrar barfed");
anRE.printStackTrace (System.err);
}
}
}
When I register the new protocol in one bundle is it then also available in
all other bundles of the application?

Yes. The OSGi framework will set the URLStreamHandlerFactory and so for your
use-case the new protocol is available when creating URLs across the whole
VM (e.g. code inside or outside bundles).
Did you have any luck tracking down exactly where the
"java.net.MalformedURLException" was thrown.
Are you running outrigger in the same process? I'm wondering if it's
possible that we're seeing the exception from another process?
Some other good places to stick some breakpoints:
org.eclipse.osgi.framework.internal.protocol.StreamHandlerFa ctory.createURLS
treamHandler(...)
-- let you walk through the protocol discovery step
org.eclipse.osgi.framework.internal.protocol.NullURLStreamHa ndlerService.ope
nConnection(...)
-- to check if your protocol has been unregistered (in which case your
URLStreamHandlerService is replaced with the "null" implementation)

That's my best guess at the moment. It would still be good to verify where
the exception is being thrown in the debugger. ;)
I've run the LUS but not Outrigger or other spaces implementation "in" an
OSGi environment however it should be doable. That said, it should be fine
and perhaps simpler to use and configure Outrigger as is so long as an
"ahttp" URLStreamHandler is available to the VM runnning it.
