java web spider

I need a project written in Java that can search/spider portal [login to view URL] and get parameters of the found objects. The program should get id as input to the category of searches and the number of hours until the end of the auction [should not be taken earlier than this]. On the output should return the name, the price [or 'Kup teraz!' parameter], the popularity and the ending date. All of these parameters are available from the listing [no need to go into details of the auction] The project should involve transfer of sources.
