This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
In the JSP include files for my project, I use absolute path (starts with /) for the links since those files are included in JSPs that are located in different levels. However, a link such as "/about" ended up as "http://localhost:8080/about". To solve the problem, currently I included the name of the webapps in the path, such as "/myapp/about", but those links would become broken when deployed to a production server.
