Question

I have exported Spring managed service beans into RMI service using 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 my spring configuration file(deploy my application in Tomcat), it throws 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 out..Thanks in advance

I also created an rmi client for consuming 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 get 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)

Please check this guys…Thanks again

Answer 1

I think if you remove the registryHost property it will dynamically create a host on 1099 since there isn’t one already.

<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 an RmiRegistry on 1099.
