I have pure FreeRADIUS server and JRadius client. I've written this example code:


RadiusClient radiusClient = null;
try {
radiusClient = new RadiusClient(InetAddress.getByName("MY_HOSTNAME"),
"MY_SHARED_SECRET");
radiusClient.setAuthPort(1812);
radiusClient.setAcctPort(1813);
} catch (UnknownHostException e) {
// DO SOMETHING
}

AttributeList attributeList = new AttributeList();
attributeList.add(new Attr_UserName("test"));
attributeList.add(new Attr_CryptPassword("teH0wLIpW0gyQ"));
// AND SO ON

RadiusPacket request = new AccessRequest(radiusClient, attributeList);

RadiusPacket reply = null;
try {
reply = radiusClient.authenticate((AccessRequest) request,
new PAPAuthenticator(), 5);
} catch (UnknownAttributeException e) {
// DO SOMETHING
} catch (RadiusException e) {
// DO SOMETHING
}
// MORE CODE FOLLOWS

and I got this:


Exception in thread "main" java.lang.NullPointerException
at net.jradius.client.auth.PAPAuthenticator.processRequest(PAPAuthenticator.java:46)
at net.jradius.client.RadiusClient.authenticate(RadiusClient.java:323)
at rc.Rc.main(Rc.java:65)


Any help will be appreciated.
