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 | 2006-12-14 16:14:06,401 DEBUG [com.njw.NWLoginProvider] getId() started - returning id="si:njw-sso:njw:login" | 2006-12-14 16:14:06,401 DEBUG [org.jboss.security.valve.PlainSSOAutoLogin] ssoLogin() loginProvider=NWLoginProvider si:njw-sso:njw:login | 2006-12-14 16:14:06,401 DEBUG [com.njw.NWLoginProvider] exists(username) started - username=fgfgfgfgfgfgfgfgfgf | 2006-12-14 16:14:06,401 DEBUG [org.jboss.security.valve.PlainSSOAutoLogin] ssoLogin() success=true | 2006-12-14 16:14:06,417 DEBUG [com.njw.NWLoginProvider] processSSOLoginNotification() logonContext=org.jboss.security.idm.LoginContext@f2ff9b | 2006-12-14 16:14:06,417 ERROR [STDERR] java.lang.ClassCastException: [Ljava.lang.Object; | 2006-12-14 16:14:06,417 ERROR [STDERR] at org.jboss.security.idm.LoginContext.getAttributeNames(LoginContext.java:99) | 2006-12-14 16:14:06,417 ERROR [STDERR] at com.njw.NWLoginProvider.processSSOLoginNotification(NWLoginProvider.java:39) | 2006-12-14 16:14:06,417 ERROR [STDERR] at org.jboss.security.valve.PlainSSOAutoLogin.ssoLogin(PlainSSOAutoLogin.java:322) | 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(); | } | } | | log from revised code | 2006-12-14 16:41:01,677 DEBUG [org.jboss.security.valve.PlainSSOAutoLogin] ssoLogin() started provider=si:njw-sso:njw:login | 2006-12-14 16:41:01,708 DEBUG [com.njw.NWLoginProvider] getId() started - returning id="si:njw-sso:njw:login" | 2006-12-14 16:41:01,708 DEBUG [org.jboss.security.valve.PlainSSOAutoLogin] ssoLogin() loginProvider=NWLoginProvider si:njw-sso:njw:login | 2006-12-14 16:41:01,708 DEBUG [com.njw.NWLoginProvider] exists(username) started - username=kkkkkkkkkk | 2006-12-14 16:41:01,708 DEBUG [org.jboss.security.valve.PlainSSOAutoLogin] ssoLogin() success=true | 2006-12-14 16:41:01,708 DEBUG [org.jboss.security.idm.LoginContext] setAttribute name=http_request value=org.apache.catalina.connector.Request@bfccfc | 2006-12-14 16:41:01,708 DEBUG [org.jboss.security.idm.LoginContext] setAttribute name=http_response value=org.apache.catalina.connector.Response@2ad6a0 | 2006-12-14 16:41:01,708 DEBUG [org.jboss.security.idm.LoginContext] setAttribute name=jboss_sso_user value=org.jboss.security.saml.SSOUser@70c242 | 2006-12-14 16:41:01,724 DEBUG [com.njw.NWLoginProvider] processSSOLoginNotification() logonContext=org.jboss.security.idm.LoginContext@e1b3b3 | 2006-12-14 16:41:01,724 DEBUG [org.jboss.security.idm.LoginContext] Attribute count=3 keyset=[http_request, jboss_sso_user, http_response] | 2006-12-14 16:41:01,724 DEBUG [org.jboss.security.idm.LoginContext] key=http_request value=org.apache.catalina.connector.Request@bfccfc | 2006-12-14 16:41:01,724 DEBUG [org.jboss.security.idm.LoginContext] key=jboss_sso_user value=org.jboss.security.saml.SSOUser@70c242 | 2006-12-14 16:41:01,724 DEBUG [org.jboss.security.idm.LoginContext] key=http_response value=org.apache.catalina.connector.Response@2ad6a0 | 2006-12-14 16:41:01,724 ERROR [STDERR] java.lang.ClassCastException: [Ljava.lang.Object; | 2006-12-14 16:41:01,755 ERROR [STDERR] at org.jboss.security.idm.LoginContext.getAttributeNames(LoginContext.java:114) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993937#...
