I have host1 and host2. java.naming.provider.url = http://host1:8080/invoker/HAJNDIFactory I start client application, it connects to server and works. Then I stop host1, and client application can't lookup new beans. I look at NamingContext in the debug mode and see that it have HttpInvokerProxy(externalURL:http://host1:8080/invoker/JMXInvokerHAServlet) NamingContext doesn't know about host2 and can't connect to host1 because it is stopped.
