一个jaas的问题，一天了也没有搞定，找不到问题。

4个文件
1.ConsoleCallbackHandler.java
package test;

import javax.security.auth.login.*;
import javax.security.auth.callback.*;
import java.io.*;

public class ConsoleCallbackHandler implements CallbackHandler {
public void handle(Callback callbacks[]) throws java.io.IOException,
UnsupportedCallbackException {
for (int i = 0; i < callbacks.length; i++) {
if (callbacks[i] instanceof NameCallback) {
NameCallback nameCb = (NameCallback) callbacks[i];
System.out.print(nameCb.getPrompt());
String user = (new BufferedReader(new InputStreamReader(System.in))).
readLine();
nameCb.setName(user);
}
else if (callbacks[i] instanceof PasswordCallback) {
PasswordCallback passCb = (PasswordCallback) callbacks[i];
System.out.print(passCb.getPrompt());
String pass = (new BufferedReader(new InputStreamReader(System.in))).
readLine();
passCb.setPassword(pass.toCharArray());
}
else {
throw (new UnsupportedCallbackException(callbacks[i],
"Callback class not supported"));
}
}
}
}

2.RdbmsLoginModule.java
package test;

import javax.security.auth.spi.LoginModule;
import javax.security.auth.callback.*;
import java.util.*;
import javax.security.auth.*;

public class RdbmsLoginModule implements LoginModule {

private CallbackHandler callbackHandler;

public RdbmsLoginModule() {
}

public void initialize(Subject subject, CallbackHandler callbackHandler,
Map sharedState, Map options) {
this.callbackHandler=callbackHandler;
String s1 = (String) options.get("url");
System.out.println(s1);
}

public boolean login() {
NameCallback nameCb = new NameCallback("user: ");
PasswordCallback passCb = new PasswordCallback("password: ", true);
Callback[] callbacks = new Callback[] {
nameCb, passCb};
try{
callbackHandler.handle(callbacks);
}catch(Exception e){
e.printStackTrace();
}

String username = nameCb.getName();
String password = new String(passCb.getPassword());

if (username.equals("songlipeng2003") && password.equals("2010525")) {
return true;
}
else {
return false;
}
}

public boolean logout() {
return false;
}

public boolean abort() {
return false;
}

public boolean commit() {
return false;
}
}

3.Hello.java
package test;

import javax.security.auth.login.*;

public class Test {
public static void main(String[] args) {
System.setProperty("javax.security.auth.login.config","./test.config");
ConsoleCallbackHandler handler=new ConsoleCallbackHandler();
try{
LoginContext lc=new LoginContext("hello",handler);
lc.login();
}catch(LoginException e){
e.printStackTrace();
}
}
}

4.test.config
hello {
test.RdbmsLoginModule required debug=true;
};

出现异常：

这些文件都放在同一个文件夹下啊，路径应该没有问题。登录config文件也应该没有问题，改了好多次了啊。都是这个错误，我从IBM下了一个和这个差不多的例子，就是可以运行，但是不知道我错到了那里啊。
