Examples of net.jini.core.lookup.ServiceRegistrar.lookup()

net.jini.core.lookup.ServiceRegistrar.lookup()
Returns the service object (i.e., just ServiceItem.service) from an item matching the template, or null if there is no match. If multiple items match the template, it is arbitrary as to which service object is returned. If the returned object cannot be deserialized, an UnmarshalException is thrown with the standard RMI semantics. @param tmpl template to match @return an object that represents a service that matches the specified template @throws java.rmi.RemoteException

        LookupLocator locator = new LookupLocator(url); // <protocol>://<hostname>
        ServiceRegistrar sr = locator.getRegistrar();
        JavaSpace space = (JavaSpace) sr.lookup(tmpl);
