Class ProgrammaticLogin

java.lang.Object
  com.sun.appserv.security.ProgrammaticLogin

public class ProgrammaticLogin
extends Object

Implement programmatic login.

This class allows deployed applications to supply a name and password directly to the security service. This info will be used to attempt to login to the current realm. If authentication succeeds, a security context is established as this user.

This allows applications to programmatically handle authentication. The use of this mechanism is not recommended since it bypasses the standard J2EE mechanisms and places all burden on the application developer.

Invoking this method requires the permission ProgrammaticLoginPermission with the method name being invoked.

There are two forms of the login method, one which includes the HTTP request and response objects for use by servlets and one which can be used by EJBs.

Method Detail

login

public Boolean login(String user,
                     String password,
                     String realm,
                     boolean errors)
              throws Exception

Attempt to login.

Upon successful return from this method the SecurityContext will be set in the name of the given user as its Subject.

On client side, realm and errors parameters will be ignored and the actual login will not occur until we actually access a resource requiring a login. And a java.rmi.AccessException with COBRA NO_PERMISSION will occur when actual login is failed.

This method is intented primarily for EJBs wishing to do programmatic login. If servlet code used this method the established identity will be propagated to EJB calls but will not be used for web container manager authorization. In general servlets should use the servlet-specific version of login instead.

Parameters:

user - User name.

password - Password for user.

realm - the realm name in which the user should be logged in.

errors - errors=true, propagate any exception encountered to the user errors=false, no exceptions are propagated.

Returns:

Boolean containing true or false to indicate success or failure of login.

Throws:

Exception - any exception encountered during Login.

login

public Boolean login(String user,
                     String password,
                     String realm,
                     HttpServletRequest request,
                     HttpServletResponse response,
                     boolean errors)
              throws Exception

Attempt to login. This method is specific to servlets (and JSPs).

Upon successful return from this method the SecurityContext will be set in the name of the given user as its Subject. In addition, the principal stored in the request is set to the user name. If a session is available, its principal is also set to the user provided.

Parameters:

realm -

errors -

user - User name.

password - Password for user.

request - HTTP request object provided by caller application. It should be an instance of HttpRequestFacade.

response - HTTP response object provided by called application. It should be an instance of HttpServletResponse.

Returns:

Boolean indicating true for successful login and false otherwise

Throws:

Exception - any exceptions encountered during login

logout

public Boolean logout()

Attempt to logout.

logout

public Boolean logout(boolean errors)
               throws Exception

Attempt to logout.

Parameters:

errors, - errors = true, the method will propagate the exceptions encountered while logging out, errors=false will return a Boolean value of false indicating failure of logout

Boolean containing true or false to indicate success or failure of logout.

Throws:

Exception - encountered while logging out, if errors==false

logout

public Boolean logout(HttpServletRequest request,
