    Default 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(
            SmtpServer svr = (SmtpServer) ctx.getBean("dssServer");
    and here is the error message:


    betha-smtp.jar;D:\dss\smtp\lib\subethasmtp.jar;D:\dss\sm tp\conf\smtp2mq com.ds

    Default Re: Instantiation of bean failed

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