Not able to create RmiProxyFactoryBean

[c2tarun]

Hi friends,

I am trying to implement the example on page: http://codetojoy.blogspot.in/2007/12...r-i-heart.html

in RAD(eclipse). I am able to Run the server program properly but when I trying to run the client program I am getting BeanCreationException when trying to inject RmiProxyFactoryBean object.

Can anyone please help?

Post code and stacktrace. When doing so use [ code][/code ] tags.

Post code and stacktrace. When doing so use [ code][/code ] tags.

Here are the service side classes:

package com.service;

public class MathServiceImpl implements MathService {

	@Override
	public int add(int a, int b) {
		// TODO Auto-generated method stub
		return a+b;
	}

	@Override
	public int pro(int a, int b) {
		// TODO Auto-generated method stub
		return a*b;
	}

}

package com.service;

import org.springframework.context.ApplicationContext;

public class MathServiceStart {

	public static void main(String[] args) {
		try {

			ApplicationContext ctx = new ClassPathXmlApplicationContext(
					"MathService.xml");

		} catch (Exception e) {
			System.out.println("Inside catch");
			e.printStackTrace();
		}

	}

}

Service XML (MathService.xml)

	<bean id="mathService" class="com.service.MathServiceImpl" />
	<bean
		class="org.springframework.remoting.rmi.RmiServiceExporter">
		
		<property name="serviceName" value="MathService"/>
		<property name="service" ref="mathService"/>
		<property name="serviceInterface" value="com.service.MathService"/>
		<property name="registryPort" value="9911"/>
	</bean>

CLIENT side codes

package com.math.caller;


public class MathCaller {
	
	private MathService ms;

	public MathService getMs() {
		return ms;
	}

	public void setMs(MathService ms) {
		this.ms = ms;
	}
	
	public void add() {
		System.out.println(ms.add(10, 20));
	}
	
	public void pro() {
		System.out.println(ms.pro(5, 25));
	}
	
}

package com.math.caller;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MathCallerClient {
	
	public static void main(String[] args) {
		ApplicationContext bf = new ClassPathXmlApplicationContext("client.xml");
		MathCaller mc = (MathCaller) bf.getBean("mathCaller");
		
		mc.add();
		mc.pro();
	}

}

Client side XML

	<bean id="MathService"
		class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
		
		<property name="serviceUrl" value="rmi://localhost:9911/MathService"/>
		<property name="serviceInerface" value="com.math.caller.MathService"></property>
	</bean>

	<bean id="mathCaller" class="com.math.caller.MathCaller">
		<property name="ms" ref="MathService" />
	</bean>

When I am executing MathServiceStart class I am getting no error or exception. But when I am executing to access the RMI service I am getting the following exception.

Have you read the stacktrace?
