Thread: Instantiation of bean failed

Hi, I'm trying to get a java daemon running. It was written in a Linux environment and I'm trying to get it to run in XP. The problem is probably with a missing dependency, but I'm very new to java and really don't know what the error message means or where to look for answers.

Here is the code:

package com.dss.xrp.smtp.bootstrap;
 
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
 
import com.dss.xrp.smtp.SmtpServer;
 
public class Bootstrap {
 
    public static void main(String[] args) {
 
        AbstractApplicationContext ctx = new ClassPathXmlApplicationContext(
                "smtp-server-context.xml");
        ctx.start();
        SmtpServer svr = (SmtpServer) ctx.getBean("dssServer");
        svr.start();
    }
 
}

and here is the error message:

I'd appreciate some guidance

ClassNotFoundException - meaning the virtual machine cannot find a class. Maker sure all required libraries on are the classpath
