Spnego keytab test gives a java security exception

Spnego keytab test gives a java security exception

I cannot get the following program running:
import java.net.URL;
import net.sourceforge.spnego.SpnegoHttpURLConnection;
public class HelloKeytab {
public static void main(final String[] args) throws Exception {
System.setProperty("java.security.krb5.conf", "krb5.conf");
System.setProperty("sun.security.krb5.debug", "true");
System.setProperty("java.security.auth.login.config", "login.conf");
SpnegoHttpURLConnection spnego = null;
try {
spnego = new SpnegoHttpURLConnection("spnego-client");
spnego.connect(new
URL("http://as1.test.local/hello_spnego.jsp"));
System.out.println("HTTP Status Code: "
+ spnego.getResponseCode());
System.out.println("HTTP Status Message: "
+ spnego.getResponseMessage());
} finally {
if (null != spnego) {
spnego.disconnect();
}
}
}
}
I installed JDK7 and set the JAVA_HOME environment variable as an
Administrator. I am working on a Windows XP machine as a regular domain
user while compiling and running.
I have the spnego-r7.jar in the same directory as the HelloKeytab.java and
I compiled with:
javac -cp .;spnego-r7.jar HelloKeytab.java
which succesfully creates the class.
When I run the program with:
java -cp .;spengo-r7.jar HelloKeytab
I get the following error:

What is wrong that I am getting this error?
