Because Java is a static language you have to create a .java file
corresponding to GnomeKeyringDbusInterface. Either you can write that by
hand, or you can use CreateInterface (comes with dbus-java) to convert
introspection to  java.

Once you have that compiled with the rest of your source, you can simply
cast the remote object to the right type. If you specify the type when
creating the object you don't even need the cast, and it saves a round
trip when the bindings introspect for you. Once you have an object of
the correct type you can just call methods as if they are local.

So, the code would look like:

   ... // connect to the bus etc
   GnomeKeyringDbusInterface remoteObject;
   remoteObject = conn.getRemoteObject("org.gnome.seahorse", "/org/gnome/seahorse/keys", GnomeKeyringDbusInterface.class)
   remoteObject.GetKeyTypes();

or

   GnomeKeyringDbusInterface remoteObject;
   remoteObject = (GnomeKeyringDbusInterface) conn.getRemoteObject("org.gnome.seahorse", "/org/gnome/seahorse/keys")
   remoteObject.GetKeyTypes();

This should (hopefully) all be documented at
http://dbus.freedesktop.org/doc/dbus-java
