Registering URL protocol handlers

Question

I'm having some trouble registering URL protocol handlers in WebLogic. The handler I wish to register is not an existing one (like http or https) so it should not conflict with any of the built in ones.
<pre>
// PROTOCOL_PACKAGE defined as java.protocol.handler.pkgs
// HANDLER_PACKAGE is defined as com.xxxx.xxxx
// In that package I have a yyy package with its Handler class.
String handlers = System.getProperty(PROTOCOL_PACKAGE);
if (handlers == null) {
System.setProperty(PROTOCOL_PACKAGE, HANDLER_PACKAGE);
else if (handlers.indexOf(HANDLER_PACKAGE) == -1) {
System.setProperty(PROTOCOL_PACKAGE, handlers + "|" + HANDLER_PACKAGE);
System.out.println(System.getProperty(PROTOCOL_PACKAGE));
</pre>
The output shows that the system property is properly set:
weblogic.utils|weblogic.utils|weblogic.net|com.xxxx.xxxx
If I try to create a URL I get the following error:
java.net.MalformedURLException: unknown protocol: yyy
This same code works for me on both JBoss and using Straight Java. I looked through the documentation and scoured the Internet trying to find an alternate way to register the protocol in WebLogic, but I found none.
Is there some reason why this would not work in WebLogic?
Thanks

It seems like it's having trouble talking to the registry; perhaps the user authenticated to Windows doesn't have permissions?
You could check to see if you have access to these Windows Registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Call Integration
HKEY_CLASSES_ROOT\CLSID\{8885370D-B33E-44B7-875D-28E403CF9270}
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\PersonaMenu
The error message included isn't really that useful.  Maybe if you can attach the entire logfile to this thread we can dig into it more.
