Pls Help with this err:RemoteProxyFailureException: No matching RMI stub method found

[ankur_vedi]

Hi,

I am very new to Spring and am attempting to make 2 seperate applications communicate using Spring RMI. I have 2 applications running on Tomcat 5.5 (from Eclipse)and one application calls the method present in second using Spring RMI. But when i try to call the remote method, i am getting this error. Would be grateful for any help/ clues !!

Error
RemoteProxyFailureException: No matching RMI stub method found for: public abstract void au.com.macquarie.rmd.scorecards.service.CrwsRemote Service.saveScorecard(int); nested exception is java.lang.NoSuchMethodException: sun.rmi.registry.RegistryImpl_Stub.saveScorecard(i nt)

Remote Service

package au.com.macquarie.rmd.scorecards.service;

public interface CrwsRemoteService{

public void saveScorecard(int id);
}

Remote Service Impl
package au.com.macquarie.rmd.scorecards.service;

public class CrwsRemoteServiceImpl implements CrwsRemoteService {

public CrwsRemoteServiceImpl() {
System.out.print("GOT CALLED");
}
public void saveScorecard(int id){
System.out.println(" IT WORKS " );
}
}

Remote Service Application Context

<bean id="crwsRemoteService"
class="au.com.macquarie.rmd.scorecards.service.Crw sRemoteServiceImpl" />

<bean class="org.springframework.remoting.rmi.RmiService Exporter">
<property name="serviceName" value="CrwsRemoteService"/>

<property name="serviceInterface" value="au.com.macquarie.rmd.scorecards.service.Crw sRemoteService"/>
<!-- defaults to 1099 -->
</bean>


Client code calling remote service

I have a struts application from which i am trying to call the remote service

RemoteObject remoteObject = (RemoteObject) WebApplicationContextUtils.getWebApplicationContex t(getServlet().getServletContext()).getBean("remot eObject");

try{
remoteObject.getRemoteService().saveScorecard(111) ;
}catch(Exception e){
e.printStackTrace();
}

Client's Application Context
<bean id="remoteService" class="org.springframework.remoting.rmi.RmiProxyFa ctoryBean">
<property name="serviceUrl" value="rmi://CrwsRemoteService"/>
<property name="serviceInterface" value="au.com.macquarie.rmd.scorecards.service.Crw sRemoteService"/>
</bean>

<bean id="remoteObject" class="au.com.macquarie.rmd.workbook.struts.Remote Object">
<property name="remoteService" ref="remoteService"/>
</bean>


Please let me know if i have missed providing any other useful info. And thanks a ton in advance

Have you tried something like the following for the serviceUrl property in your client-side RmiProxyFactoryBean definition?

<property name="serviceUrl" value="rmi://localhost:1099/CrwsRemoteService"/>

Hi Mike,

Thanks for your reply. I tried that. but it still does'nt work and throws the same exception (Pls see below).

1) Do i need to 'Jar' up the application in which my service is and include it in the classpath of my client ? After all known ways failed, i have currently got the service interface , ie CrwsRemoteService, in a jar and included that in the client's classpath. Is that the correct way to do things ? Or should there be 2 different CrwsRemoteService interfaces, one at the service side and one at the client side ?

2) In my service app's applicationContext, when i add the following line, as in the Spring doc, my server does'nt even start up and the following error

<property name="registryPort" value="1199"/>

org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'remoteService' defined in ServletContext resource [/conf/applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.remoting.RemoteLookupFailureEx ception: Lookup of RMI stub failed; nested exception is java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused: connect


Error after Mike's suggestion -:
