            </languages>            
    </administration>

 </extension>

In my helloworld.php i have this code

<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');

// import joomla controller library
jimport('joomla.application.component.controller');

// Get an instance of the controller prefixed by HelloWorld
$controller = JController::getInstance('Helloworld');

// Perform the Request task
$input = JFactory::getApplication()->input;
$controller->execute($input->getCmd('task'));

 // Redirect if set by the controller
  $controller->redirect();
  ?>

Update

I did this successfully in joomla 2.5 but it is not working in the latest version of joomla. what should i do to make it work in joomla 3.0

Solution 1:[1]

check if you have added this code to your XML:

<languages>
        <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworld.ini</language>
        <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworldt.sys.ini</language>
</languages>

and:

<administration>
... 
    <languages>
            <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworld.ini</language>
            <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworld.sys.ini</language>
    </languages>
...
</administration>

and check if the files are included in your installation ZIP - in right folder, e.g.:

language/en-GB/ ...

Be aware, the path to the file can be different for your extension.

You are missing en-GB subfolder declaration in your xml file path. xml: language/en-GB.com_helloword.sys.ini while it should be language/en-GB/en-GB.helloworld.sys.ini and path: language/en-GB/en-GB.helloworld.sys.ini same pattern goes for the other language files of course.

*since your edit and source code inclusion,including your full xml code with the corrections (filepath and extension closing tag)

        </languages>            
</administration>

` (can not include the extension opening and closing tag, for some reason it wont be printed, please make sure to include them correctly)

for your other issue, in your helloworld.php you probably need to import the joomla controller library:

jimport('joomla.application.component.controller');

after the

defined('_JEXEC') or die('Restricted access');

and replace this:

$controller = JController::getInstance('Helloworld');

with this one:

$controller = JControllerLegacy::getInstance('Helloworld');
