title: BreadCrumb Implementation
body: <p>I have a requirements of implementing breadcrumb in our J2EE application at both back-end and on user interface.
  I only know what is breadcrumb but not aware of its other technical aspects as i have head that it also help in SEO and other things.</p>
  
  <p>My question is what things one need to be take care while developing such functionality like one few approaches i can think of</p>
  
  <ol>
  <li>Put user traversing path in the session and can use that to build breadcrumb.</li>
  <li>Like in product detail page instead how user navigate show the path as 
  Catalogue->Category->Product.</li>
  </ol>
  
  <p>Please suggest me what best approach one should have, also if any one can refer a sample implementation in Java for the breadcrumb that will be an added bonus for me to move ahead</p>
