I find Joomla non-developer friendly for the most of the time; documentation is poor and not having any continuity. I searched the net for displaying errors to the screen in Joomla 1.5 and up and here is the code: JError::raiseWarning(’101′, “message to be displayed”); This bunch of code is especially useful if you are developing extended classes for Joomla, such that if you are developing a authentication plugin for Joomla:

<?php
defined(‘_JEXEC’) or die();
jimport(‘joomla.event.plugin’);
// class plg<type><name> extends JPlugin

class plgAuthenticationMSN extends JPlugin

{

function plgAuthenticationMSN(& $subject, $config) {

parent::__construct($subject, $config);

}
function onAuthenticate( $credentials, $options, &$response )

{
$err = “IP:”.$remoteCpIP.” port:”.$port;

JError::raiseWarning(’101′, $err);
if ($success)

{

$response->status          = JAUTHENTICATE_STATUS_SUCCESS;

$response->error_message = $err;

$response->email     = $email;

$response->fullname = $credentials['username'];

}
else

{

$response->status         = JAUTHENTICATE_STATUS_FAILURE;

$response->error_message    = ‘Failed to authenticate: ‘ . $message;

}

}

}

?>

This is  the only way to see the errors on the screen,”echo” and other stuff doesn’t show anything as you are inside a class.
