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!

It is often considered courteous to explain how you solved your problem.

Others may find your post while looking into a similar problem, and
would benefit from your explanation.

Some day someone will have the same problem as you, find you question
in Google then curse you for refusing to share your solution.
