For 2)

Not sure what you're using for a server, but if you're using Tomcat you can
implement the LifecycleListener interface by doing something like this:

package mycompany.mypackage;

import org.apache.catalina.LifecycleListener;
import org.apache.catalina.LifecycleEvent;

public class MyService implements LifecycleListener
    // other methods here as needed

    // respond to lifecycle events
    public void lifecycleEvent(LifecycleEvent event)
        if (event.getType().equals("start"))
            //do initialization stuff here

You'll need to add the listener in your server.xml file so that tomcat knows
to call it:

<Context path="/axis" docBase="axis" debug="0" reloadable="true">
         <Listener className="mycompany.mypackage.MyService"/>

This has worked good for me, but there may be other ways to accomplish what
you want to do.
