The ability to generate HTML or .JSP fragments that you can include on multiple pages of your site enables you to re-use code and increase maintainability.
However, if you need to include functions (or methods) and fields (or variables) in one fragment that is included on a page and then utilize them in another fragment included in the same page Eclipse will give you compile errors because it concludes that your references are out of scope.

vim, ncurses, tcsh
Simply type them into the search field and then check off → Continue reading “Setting up Cygwin, Linux Command Line, on a Windows Box”
It is very convenient to pass JSON data from client to server and between different server-side components. However, JSON data is an inherently unordered data structure and in many cases a developer will want to render a list of items in some specified order.
One way that I found to do so is to append an integer to the keys in your data when generating the JSON data. For example, you might be iterating through a database result set and → Continue reading “Applying Order to JSON Data When Rendering to a Page”
