I found what I believe to be a better solution to this bug. I just added the following code before calling SwingUtilities or any Swing related component method. It create a new AppContext for the RMI Thread (RMI thread must be the current Thread when running the code below). if(AppContext.getAppContext() == null){ SunToolkit.createNewAppContext(); } Due … Read more
Keep a strong reference to the object that implements the java.rmi.Remote interface so that it remains reachable, i.e. ineligible for garbage collection. Below is a short program that demonstrates a java.rmi.NoSuchObjectException. The script is self-contained, creating an RMI registry as well as a “client” and a “server” in a single JVM. Simply copy this code … Read more
RMI generally won’t work over a firewall, since it uses unpredictable ports (it starts off on 1099, and then runs off with a random port after that). In these situations, you generally need to resort to tunnelling RMI over HTTP, which is described well here.
This is item A.1 in the RMI FAQ. You need to either fix your /etc/hosts file or set the java.rmi.server.hostname property at the server.
The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of: a) The IP/domain or port is incorrect b) The IP/domain or port (i.e service) is down c) The IP/domain … Read more
Contrary to common belief JMX/RMI doesn’t need to open all these ports. You can actually force them to be same which will mean that at the end of the day you’ll only need to punch one hole in the firewall (if firewall is your concern). Try setting System Properties: com.sun.management.jmxremote.port com.sun.management.jmxremote.rmi.port to the same value!! … Read more
Run the rmiregisrty command from your /bin, /build, or /build/classes folder, whichever folder is the root of your built files. I spent half a day trying to solve that same thing.
There are four cases of this exception. When exporting: you didn’t run ‘rmic’ and you didn’t take the steps described in the preamble to the Javadoc for UnicastRemoteObject to make it unnecessary. When binding: the Registry doesn’t have the stub or the remote interface or something they depend on on its classpath. when looking up: … Read more
