calculation interface there should method takes string parameter.

public interface calculation {   void print(string text );   void registeripaddress(string ip); }   public class calculationimpl implements calculation {  @override void print(string text) {     system.out.println(text); }     @override     void registeripaddress(string ip){             list.add(ip);//or whatever want } 

your xml files both client , host right applicationcontext.xml

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd">  <bean id="calculationbean" class="com.javatpoint.calculationimpl"></bean> <bean class="org.springframework.remoting.rmi.rmiserviceexporter">     <property name="service" ref="calculationbean"></property>     <property name="serviceinterface" value="com.javatpoint.calculation"></property>     <property name="servicename" value="calculationservice"></property>     <property name="replaceexistingbinding" value="true"></property>     <property name="registryport" value="1099"></property> </bean> </beans> 

client-beans.xml

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd">  <bean id="calculationbean" class="org.springframework.remoting.rmi.rmiproxyfactorybean"> <property name="serviceurl" value="rmi://localhost:1099/calculationservice"></property> <property name="serviceinterface" value="com.javatpoint.calculation"></property> </bean> </beans> 

create new instance of applicaioncontext in order work

class server {     public static void main(string[] args) {         applicationcontext context = new classpathxmlapplicationcontext("applicationcontext.xml");     } } 

need run client

public static void main(string[] args) {     applicationcontext context = new classpathxmlapplicationcontext("client-beans.xml");     calculation calculation = (calculation) context.getbean("calculationbean");     calculation.print("copied&pasted!");      try {         calculation.registeripaddress(inetaddress.getlocalhost().gethostaddress());     } catch (unknownhostexception e) {         // todo auto-generated catch block         e.printstacktrace();     } } 

upon googling can see method

public static string getclienthost()                             throws servernotactiveexception 

now need extend remote server class can't achieve same thing in spring rmi itself
