Code sample - A better launcher using ApplicationContext

By Dmitri Toubelis

I use Spring/Hibernate combination in my callback function and I could not make Hibernate transactions to work even though exactly same configuration worked just fine with web application. I tried couple of things and solution was to use ApplicationContext instead of BeanFactory. I modified Launcher.java for this and my version is attached. It has slightly extended behaviour also - it accepts multiple configuration files on command line, which I find quite useful.

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

import com.coldcore.coloradoftp.core.Core;
import com.coldcore.coloradoftp.factory.ObjectFactory;
import com.coldcore.coloradoftp.factory.ObjectName;
import com.coldcore.coloradoftp.factory.impl.SpringFactory;

/**
