including jquery.ui 1.6 directly from theme.info It is possible? because i've tried to include jquery ui library through drupal.org/project/jquery_ui module (followed instructions in readme.txt) but that library won't show up in source code. What's the problem?

Should i go for jquery_ui module or i can include that script through .info file?

Jquery ui version = "6.x-1.5"
Downloaded jquery ui library 1.6
The correct way to include jQuery UI, from README.txt:

In your module, call the following function:

jquery_ui_add($files);


For example:

jquery_ui_add(array('ui.draggable', 'ui.droppable', 'ui.sortable'));
jquery_ui_add('ui.sortable');  // For a single file
