/**
 * Retrieve the portfolios feed using the Finance service and
 * the portfolios feed uri. In GData all get, insert, update
 * and delete methods always receive a callback defining success
 * and failure handlers./*from ww  w . java  2s  . c  o m*/
 * Here, the failure handler displays an error message while the
 * success handler obtains the first Portfolio entry with a title
 * starting with "GWT-Finance-Client" and calls deletePortfolio
 * to delete the portfolio. Alternatively we could also have used
 * targetPortfolio.deleteEntry but the effect is the same.
 * If no portfolio is found a message is displayed.
 * 
 * @param portfoliosFeedUri The uri of the portfolios feed
