Hello, for customizing Jboss Portal i customized the JSPs for the navigation and included a tree-like navigation and breadcrumbs. So far this all is just made by changing the existing JSPs... Now i need to get an API, so every portlet is able to include content to the breadcrumbs (what means 1 name and 1 url for every breadcrumb). this way the breadcrumbs shall be able to be extended and be a navigation help for portlets. Since i am new to web developing i would like to ask the community for an short concept idea on how this could be realized best.
