RMIServiceExporter not working, not connecting to RMI localhost on port 1099
I exported Spring managed beans service to RMI service using the following configuration:
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
<property name="serviceName" value="spitterService"/>
<property name="service" ref="spitterService"/>
<property name="serviceInterface" value="com.spitter.service.SpitterService"/>
<property name="registryHost" value="127.0.0.1"/>
<property name="registryPort" value="1099"/>
</bean>
but when i load Spring config file (deploy my app to Tomcat) it throws the following exception
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.remoting.rmi.RmiServiceExporter#0' defined in ServletContext resource [/WEB-INF/spitter-servlet.xml]: Invocation of init method failed; nested exception is java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:

please help me. thanks in advance
I also created an rmi client to use the RMI service
public class SpitterMain {
public static void main(String[] args){
String serviceURL = "rmi://localhost:1099/spitterService";
try {
SpitterService spitterService = (SpitterService) Naming.lookup(serviceURL);
Spitter spitter = spitterService.getSpitter("panneerselvam");
List<Spittle> spittles = spitterService.getSpittlesForSpitter(spitter.getId(), 25);
System.out.println("Welcome>"+spitter.getName()+"( "+spitter.getUsername()+" )");
System.out.println("Your Recent Spittles are:");
for(Spittle spittle: spittles){
System.out.println(spittle.getText()+" ON "+spittle.getWhen());
}
} catch (NotBoundException ex) {
Logger.getLogger(SpitterMain.class.getName()).log(Level.SEVERE, null, ex);
} catch (MalformedURLException ex) {
Logger.getLogger(SpitterMain.class.getName()).log(Level.SEVERE, null, ex);
} catch (RemoteException ex) {
Logger.getLogger(SpitterMain.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Now I am getting the following exception.
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: org.springframework.remoting.rmi.RmiInvocationHandler (no security manager: RMI class loader disabled)

I think that if you remove the property registryHost
, it will dynamically create the host at 1099 as it is no longer there.
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
<property name="serviceName" value="spitterService"/>
<property name="service" ref="spitterService"/>
<property name="serviceInterface" value="com.spitter.service.SpitterService"/>
<property name="registryPort" value="1099"/>
</bean>
Either that or start RmiRegistry at 1099.

You have to create myRmiExporter
and extend RMIServiceExporter
and then implement this method with this body
protected Registry getRegistry(String registryHost, int registryPort,
RMIClientSocketFactory clientSocketFactory, RMIServerSocketFactory serverSocketFactory)
throws RemoteException
{
if (registryHost != null)
{
// Host explictly specified: only lookup possible.
if (logger.isInfoEnabled())
{
logger.info("Looking for RMI registry at port '" + registryPort + "' of host [" + registryHost + "]");
}
try
{
Registry reg = LocateRegistry.getRegistry(registryHost, registryPort, clientSocketFactory);
testRegistry(reg);
return reg;
}
catch (RemoteException ex)
{
logger.debug("RMI registry access threw exception", ex);
logger.warn("Could not detect RMI registry - creating new one");
// Assume no registry found -> create new one.
LocateRegistry.createRegistry(registryPort);
Registry reg = LocateRegistry.getRegistry(registryHost, registryPort, clientSocketFactory);
testRegistry(reg);
return reg;
}
}
else
{
return getRegistry(registryPort, clientSocketFactory, serverSocketFactory);
}
}
Works
