getResourceAsStream() problem

Hello, I have a problem with getResourceAsStream().

I'm using these tools: Eclipse JEE edition version 3.5.1 with the Apache
CXF plugin and Apache Tomcat version 6.0.20. Java is version 6. This is
under Windows.

I've written a very simple JAX-WS web service, here's the complete code:

package bioweb;

import java.rmi.Remote;
import java.rmi.RemoteException;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(name="BioWebInterface", targetNamespace="http://bioweb/")
public interface BioWebInterface extends Remote {
    @WebMethod(operationName="sayHello", action="urn:SayHello")
    public String sayHello() throws RemoteException;
}

package bioweb;

import java.io.InputStream;
import java.rmi.RemoteException;

import javax.annotation.PostConstruct;
import javax.jws.WebService;

@WebService(targetNamespace="http://bioweb/",
endpointInterface="bioweb.BioWebInterface", portName="BioWebPort",
serviceName="BioWebService")
public class BioWeb implements BioWebInterface {

    @Override
    public String sayHello() throws RemoteException {
       return "Hello from the BioWeb Web Service!";
    }

    @PostConstruct
    protected void init() {
       System.out.println("I'm in the postconstruct method.");

       InputStream is1 =
getClass().getClassLoader().getResourceAsStream("get-all-model-links.xquery");
       InputStream is2 =
BioWeb.class.getClassLoader().getResourceAsStream("get-all-model-links.xquery");

       if (is1 != null && is2 != null) {
          System.out.println("Successfully loaded resource using both
methods!");
       }
       else if (is1 != null) {
          System.out.println("Successfully loaded resource using method
1.");
       }
       else if (is2 != null) {
          System.out.println("Successfully loaded resource using method
2.");
       }
       else {
          System.err.println("Not successful at all in loading the
resource!");
       }
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
       new BioWeb().init();
    }
}

I've created folder called xqueries and added it to the classpath (under
project properties->java build path->libraries tab->add class folder
button and in it I have an XQuery file named get-all-model-links.xquery
(will be lots more later).

When I run the BioWeb class like a normal Java program (by invoking
main(), which calls init(), I can load the XQuery resource fine, the
output is:
I'm in the postconstruct method.
Successfully loaded resource using both methods!

However, when run as a service (then Tomcat calls the init() method due
to its @PostConstruct annotation), the loading of the resource fails.
The output is:
I'm in the postconstruct method.
Not successful at all in loading the resource!

It seems that the class folder I added isn't visible anymore or maybe
the "URL:s" need to be altered when in this context. I'm very new at
this web stuff and I need help, I've had this problem for two days now. :(
I'm doing all the interfacing with Tomcat via Eclipse btw, and I haven't
really tampered with any settings for it.

Thanks for reading and for any replies!
