    • WSCallbackHandlerImpl

      public WSCallbackHandlerImpl(String userName, String realmName, String password)

      Push the username and password to login module. The realmName is only need if it's different from the current realm. If you intend to login to the current realm, you do not need to specify a realm or you can specify the current realm.

      In the client container, the realm is ignored and instead the realm from the target server is used.

      Parameters:
      userName - The user name of the principal.
      realmName - The realm name, if different from the current realm; ignored on the client container
      password - The password in clear text.

    • WSCallbackHandlerImpl

      public WSCallbackHandlerImpl(String userName, String realmName, String password, Map appContext)

      Push the username and password to login module. The realmName is only needed if it's different from the current realm. If you intend to login to the current realm, you do not need to specify a realm or you can specify the current realm.

      If the realm you specify is different from the current realm and you want to validate the userid/password at the new target realm during this login, then you must specify a java.util.Map which contains the following properites: javax.naming.Context.PROVIDER_URL Example: "corbaloc:iiop:myhost.mycompany.com:2809" javax.naming.Context.INITIAL_CONTEXT_FACTORY Example: "com.ibm.websphere.naming.WsnInitialContextFactory" Note: If the target server is not a WebSphere server, then do not specify this information since it will not validate successfully. Also, the target server must support CSIv2 in order for the userid/password to be successfully sent.

      In the client container, the realm is ignored and instead the realm from the target server is used.

      Parameters:
      userName - The user name of the principal.
      realmName - The realm name, if different from the current realm; ignored on the client container
      password - The password in clear text.
