Problems with running compiled code

Hello there,
I have an MTA application called power mta which has a java api to send email into it. I have placed the jar file provided into the jre/lib/ext directory and the example code compiled without a problem. However, when I run the app I get the following error:

C:\Documents and Settings\Administrator\Desktop\MPFeeder\examples>java ExampleMe
Exception in thread "main" java.lang.NoClassDefFoundError: com/port25/pmta/api/s

What does this error mean? I have called them about this and they say they cant duplicate the error. Here is the ExampleMessage.java code:

import java.io.IOException;
import com.port25.pmta.api.submitter.*;

public class ExampleMessage {
    public static void main(String args[]) {
        String text =
            "Subject: Sent using the PMTA Java API\n" +
            "To: To You <rick@infotech.com>\n" +
            "From: From Me <rick@infotech.com>\n" +
            "\n" +
            "This message was sent via PowerMTA's native Java API.\n";
        Message msg = new Message("rick@infotech.com");
        try {
            Recipient rcpt = new Recipient("rick@infotech.com");
            Connection conn = new Connection("local:");
        catch (ServiceException se) {
        catch (EmailAddressException eae) {
        catch (IOException ioe) {

Can someone please tell me what I am doing wrong? The correct fix is worth 500 points.

The compiler uses a different VM than when you run your app.
So you need to also place the jar in your JRE's ext directory.
The JRE is probably installed under Program Files.
