htaccess expert required

Hi, I have a joomla site and a wordpress site installed in two separate directories on my server, in the root htaccess file of the server, i need a htaccess rule written. The rule will basically redirect the joomla blog urls to wordpress urls. the post names will be the same. But currently joomla urls have "joomla /[login to view URL]" in them, which will need to be removed, all the rest of the url will be the same as wordpress url. Please let me know if not clear. Thanks
