default Authentication provider

  Asked By: Loretta    Date: Nov 29    Category: Java    Views: 1530
  

it´s about 3days that I´m trying to create a user in WLS8.1
dynamically by using the following class , I use this class in a
signup page flow ,I´d made the roles and groups and did role
assignment to groups .Surprisingly I got a null exception which caused
by javax.management.MBeanException ,I´d searched in forums.bea.com but
no result came! ,here is the code i run for adding a user .
userManager=new
UserManager("weblogic","weblogic","t3://localhost:7001","portalServer");
userManager.addUser(aForm.username,aForm.password,"signed
up bonusClient user" );

I even don´t know what to put in url field http:// or ldap:// or t3://
I used the t3 because I found a sample in forums that used it ,I
think it should be related to transactions that I haven´t did anything
about it in the configuration of portal server.

and the UserManager Class:

try
{

}
catch (Exception e){
throw new BlankException(e.getMessage()+e.getCause());

}
}
return true;
}
return false;

}

upEditor =(UserPasswordEditorMBean)providers[i];

try
{
upEditor.changeUserPassword(username,oldPsw,newPsw);
}
catch (Exception e)
{

}
}

}

}
public void createUser2(){
try {

DefaultAuthenticatorMBean dbean =
(DefaultAuthenticatorMBean) cmbs.getMBean(new
ObjectName("Security:Name=myrealmDefaultAuthenticator"));
//create a new user
dbean.createUser("testuser", "password", "a test user");
//create a new group
dbean.createGroup("testGrp","a test group");
//add the user to group
dbean.addMemberToGroup("testGrp","testuser");

} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (InvalidParameterException e) {
e.printStackTrace();
} catch (JMException e) {
e.printStackTrace();
} catch (AlreadyExistsException e) {
e.printStackTrace();
} catch (NotFoundException e) {
e.printStackTrace();
}
}

}


I have tested two ways by two different methods .addUser() and
.createUser() ,both of them throw the same Exception , firstly , I
thaugh I might be cause by not setting the MBeans in my class pass ,
but after setting it , no changes came up!
