the Internet face a common problem: there are so many interesting links which they not only would like to come back to at some point, but which are also interesting to others -- for example, colleagues who share a corporate intranet, and who are intereste
Tutorial Details:
the web is a very dynamic medium, and links are bound to be migrated to some other location, or vanish entirely for any number of reasons. So these web pages have to be maintained. This process, however, is almost impossible to handle manually, since you\'d have to click on each link, see what happens, and update the HTML code manually depending on the response received. With hundreds of links in a typical collection, this is clearly not practical. The lack of a solution to this problem sooner or later leads to frustrating user experiences because of many broken linksthe web is a very dynamic medium, and links are bound to be migrated to some other location, or vanish entirely for any number of reasons.

URLManage manages all interactions with the link data in the backend storage, which is a relational database system. This RDBMS stores the data in some tables, and either a new database needs to be set up, or an existing database can be used to hold these tables. URLManage relies on the DBAccessor package, a JDBC wrapper that I developed earlier. URLManage creates, modifies, deletes, and retrieves link data, and manages the database schema itself.
URLCheck automatically checks the links stored in the database against the network; that is, URLCheck tries to connect to that network resource and determine its status .The actions taken (such as updating or removing a link in the database) depend on the status response received.
URLPublish creates web pages using the Velocity template engine, an Apache Jakarta project. The link data from the database is combined with a template web page to create the actual HTML output required for publishing.
