[jboss-user] [Security & JAAS/JBoss] - Classcast exception in LoginContext.getAttributeNames()

[njw]

Me again :-)

I've implemented my own login provider, and to try to get a better understanding of whats being passed into it I added some debugging.

However, I added a call to LoginContext.getAttributeNames() and am now getting a ClassCast exception from the getAttributeNames() method :-

  | 2006-12-14 16:14:06,370 DEBUG [org.jboss.security.valve.PlainSSOAutoLogin] ssoLogin() started provider=si:njw-sso:njw:login

my code :-

  | public void processSSOLoginNotification(LoginContext argLoginContext) throws IdentityException {
  | 		this.loginContext = argLoginContext;
  | 		log.debug("processSSOLoginNotification() logonContext=" + this.loginContext);
  | 	
  | 		String[] attributes = this.loginContext.getAttributeNames();
  | 

decompiled LoginContext code

  | public final class LoginContext
  |     implements Serializable
  | {
  | 
  |             public LoginContext()
  |             {
  | /*  41*/        contextMap = null;
  | /*  67*/        contextMap = new HashMap();
  |             }
  | 
  |             public Object getAttribute(String name)
  |             {
  | /*  78*/        return contextMap.get(name);
  |             }
  | 
  |             public void setAttribute(String name, Object value)
  |             {
  | /*  89*/        contextMap.put(name, value);
  |             }
  | 
  |             public String[] getAttributeNames()
  |             {
  | /*  99*/        return (String[])(String[])contextMap.keySet().toArray();
  |             }
  | 
  |             private Map contextMap;
  |             public static final String HTTP_REQUEST = "http_request";
  |             public static final String HTTP_RESPONSE = "http_response";
  |             public static final String SSO_USER = "jboss_sso_user";
  | }
  | 

revised code with additional debugging

  |     public String[] getAttributeNames()
  |     {
  |     	if (contextMap == null){
  |     		log.debug("no attributes");
  |     		return null;
  |     	}
  |     	else
  |     	{
  |     	log.debug("Attribute count=" + this.contextMap.size() + " keyset=" + contextMap.keySet());
  |     	for (Object key:contextMap.keySet()) {
  |     		log.debug("key=" + key + "       value=" + this.contextMap.get(key) );
  |     	}
  |     	
  |         return (String[])this.contextMap.keySet().toArray();
  |     	}
  |     }
  | 
  |
